Mobile welding rig
Engine-driven welder, stick and wire, cutting torch
Landing gear, crossmembers, frame cracks, and underride guards. Structural trailer repair is welding first and mechanics second.
Need trailer repair in Pomona? We run mobile trailer repair to the dock, the yard, or the shoulder — brakes, air lines, lights, landing gear, doors, and suspension, loaded or empty. CA-60, CA-57, and CA-71 all run through Pomona, so most calls come off one of those.

Trailer work splits between structural repair and air-brake work, and the two need completely different trucks. A Pomona dispatch that arrives without a welder cannot fix a landing gear, and one without air tooling cannot release the brakes.
Engine-driven welder, stick and wire, cutting torch
Landing gear, crossmembers, frame cracks, and underride guards. Structural trailer repair is welding first and mechanics second.
Gauges, line stock, glad hands, fittings, caging tools
Any trailer that cannot build or hold air. Frequently a ten-minute fix that otherwise becomes a tow.
Shoe and drum service, slack gauges, pushrod travel measurement
Out-of-adjustment findings and roadside brake failures. The measured stroke is what an inspector goes by, not appearance.
Rated for loaded tandem lifting, cribbing
Bearing, hub, drum, and suspension work. A loaded trailer is lifted on rated equipment or not at all.
Trailer ABS ECU interface, sensor testing
Amber lamp faults. Guessing at a wheel speed sensor replaces good parts and leaves the lamp on.
LED lamps, harness, noseboxes, conspicuity tape
Carried on every call so a lighting violation clears on the first visit rather than becoming a return trip.
Legs, gearboxes, air bags, height valves, bushings
The high-frequency failures. Stocking them is the difference between one dispatch and three days out of service.
Hardwood sections, scuff liner, rivets, fasteners
Floor and panel damage found at a dock, where a shipper will not load until it is closed up.

One call puts a trailer repair unit on the road to you anywhere in Pomona or out along CA-60 and CA-57. Tell us the road and which way you are pointed and we do the rest.
Van, reefer box, flatbed, tanker, dump, and container chassis worked on where the trailer sits across the Pomona metro. A trailer failure usually strands a loaded box and a perfectly healthy tractor at the same time, which is why most of this work is mobile rather than shop.
Bent legs, stripped gearboxes, seized cranks, and sheared mounts. The single most common trailer call in Pomona — a dropped trailer that will not lift is immobile even though nothing mechanical is actually wrong with it.
Cracked crossmembers, sagging rails, and rusted-through I-beams repaired by a certified mobile welding rig. A Pomona trailer with failing crossmembers has a floor waiting to drop a forklift through it.
Worn kingpins, cracked upper coupler plates, and delaminated pickup plates. This is the one connection holding the trailer to the tractor, and it is an automatic out-of-service item on any Pomona roadside inspection.
Hardwood floor sections, laminated decking, and scuff liner. Forklift damage and rot spread from a single soft board, and a Pomona shipper can refuse to load a trailer over a hole they can see.
Torn roof sheets from dock canopies and low clearances, punctured sidewalls, popped rivets, and rub-rail damage. A wet Pomona load is a cargo claim that costs multiples of the panel.
Swing doors, roll-up doors, cables, springs, hinges, and cam locks. A Pomona trailer that will not close is a trailer that cannot legally or safely leave the dock, loaded or empty.
Ruptured air bags, failed height control valves, and broken shocks. A collapsed bag drops one corner onto the frame and destroys tires and bearings on the way to the next Pomona exit.
Broken leaf springs, worn equalizers, hangers, and torque arms. Pomona pavement joints and potholes take these apart quietly until the axle stops tracking straight.
Seized slider pins, worn rails, and air cylinders that will not release. A slider stuck in the wrong position is a Pomona weight-distribution violation you cannot fix at the scale house.
Repacking, hub replacement, and leaking wheel seals. A hot hub found on a Pomona shoulder is minutes from a wheel-off, which is the worst outcome on this entire list.
Bent axles and out-of-alignment tandems after a curb strike or a hard dock hit. Misalignment eats a set of Pomona trailer tires in weeks and pulls the whole combination sideways.
Mounting, torque, valve stems, and damaged rims. Handled on the same Pomona dispatch when a suspension failure has already taken the tire with it.
Relining, drum replacement, springs, and rollers. Brake condition is the single most cited category in Pomona roadside inspections and the fastest route to an out-of-service sticker.
Seized S-cams and out-of-adjustment automatic slacks. A Pomona trailer can pass a visual and still fail the pushrod-travel measurement an inspector actually takes.
Ruptured diaphragms, caged spring brakes, and cracked housings. A blown chamber locks a Pomona trailer in place until it is caged or replaced on scene.
Chafed lines, split hoses, frozen glad hand seals, and leaking fittings. The cheapest part on the trailer and the most common reason a Pomona driver cannot build air and leave.
Wheel speed sensors, exciter rings, ECU faults, and the amber lamp on the left rear. An inoperative ABS lamp is a documented Pomona inspection violation on its own.
Relay valves, spring brake valves, check valves, and water-fouled tanks. Wet Pomona winter air freezes valves closed overnight and strands a trailer that worked fine at shutdown.
Corroded pins, broken nosebox, and burned circuits. The first thing checked on any Pomona trailer with no lights at all, and frequently the whole repair.
Chafed harnesses, corroded grounds, and splice failures inside the rail. Intermittent Pomona lighting faults live here and are why a lamp swap did not fix it.
LED and incandescent lamp replacement across the whole required pattern. Federal rules specify which lamps must work, and a Pomona inspector counts them.
Retroreflective tape replacement to the required pattern on sides and rear. Missing or degraded tape is a cited Pomona violation and a genuine night-visibility problem.
Flaps, hangers, and rear impact guard repair. A damaged underride guard is a serious Pomona finding, not cosmetic, and the weld has to be right.
The federally required annual inspection performed on site, with the failing items repaired on the same Pomona visit rather than scheduling the trailer back into a shop twice.
Insurance-current network rescuers with verified compliance, equipment, and live availability status.
Rolling 30-day average dispatch-to-arrival, by service type, across the local rescuer network.
Google shows a "how much would it cost to fix a trailer" box on this search because nobody on page one answers it. Here is what actually makes up a Pomona trailer invoice, and which items move it the most.
Getting a stocked truck and a technician to where the trailer sits. Billed once and separate from labor. A shop visit removes this line but adds a tow and the days the trailer is gone.
The largest line on most trailer invoices. Structural and welding labor prices above general mechanical labor because of the certification and the rig.
Landing gear, crossmembers, and frame work are billed on the welding rig's time. Often the entire repair, with parts as a rounding error.
Air bags, slacks, chambers, lamps, and bearings are inexpensive and usually stocked. Landing gear assemblies, axles, and suspension components are not.
An adjustment is minutes. A full reline with drums across a tandem is a different invoice entirely — and the inspection that triggered it does not care which one you were expecting.
Trailer failures cluster at night and at docks on weekends. Emergency dispatch carries a premium tier, and a loaded trailer usually justifies it.
A loaded trailer limits what can be lifted, unhooked, or moved. Some repairs genuinely cannot start until the load comes off, which is a scheduling cost more than a parts cost.
A shoulder on an interstate, a fenced yard, or a dock door are three different jobs. Traffic control on a live roadway adds real cost and is not optional.
The federally required annual, and any repairs the inspection turns up. Cheapest when scheduled, most expensive when an officer finds it first.
A trailer placed out of service cannot legally move until the defect is corrected. That converts an ordinary repair into an emergency dispatch with a driver and a load waiting on it.
Frequently bundled, because the suspension or bearing failure that stranded the trailer already destroyed a tire on the way.
Chasing an intermittent electrical fault or an ABS code is billed time. It is also the difference between fixing it once and replacing three good parts.
Road Rescue Network does not set a member operator's rates. What the network does is make sure the truck that rolls to a trailer actually carries what the failure needs — a welding rig for structural work, air and brake tooling for a brake failure — instead of arriving, diagnosing, and leaving to come back.

The same crews that run Pomona also cover Diamond Bar (5 mi), Walnut (4 mi) and Claremont (4 mi), so a call from either side of Los Angeles County reaches the same desk.

6 exits in Pomona
The Pomona Freeway, the primary east-west truck route between East LA and the Inland Empire, running straight through Pomona. The SR-57/SR-60 confluence on the west edge is the region's worst freight choke point.

4 exits in Pomona
The Orange Freeway running north-south through Pomona toward Orange County. Its confluence with SR-60 produces some of the heaviest truck congestion in LA County.

3 exits in Pomona
The Chino Valley Freeway connecting Pomona south to the Inland Empire warehouse belt and SR-91. A key drayage and dry-van corridor with heavy grade traffic near the SR-60 split.

0 exits in Pomona
The San Bernardino Freeway just north of Pomona, the main transcontinental route east toward the Inland Empire and Arizona. Carries the heaviest long-haul volume serving the city's north industrial edge.

0 exits in Pomona
The Foothill Freeway along the San Gabriel Valley's north edge, an alternate to I-10 for freight bypassing the basin core. Reached just north of Pomona near La Verne.

0 exits in Pomona
Euclid Avenue south from Pomona into Ontario and Chino, a surface arterial heavily used by last-mile and warehouse-shuttle box trucks feeding the Inland Empire DCs.
Patterns observed across recent dispatch data in this metro, by service type and corridor.
The SR-57/SR-60 merge is a continuous stop-and-go crawl, and loaded rigs cook their brakes and cooling systems grinding through it in summer heat. We see glazed brakes, boiled coolant, and water-pump failures here weekly. Pomona service trucks carry brake, air, and cooling parts and know which connector-ramp shoulders CHP will let us work.
Port of LA and Long Beach containers heading to Inland Empire warehouses funnel through Pomona on SR-60, and a chassis brake, light, or tire failure mid-corridor stalls the whole move. We prioritize drayage breakdowns through the confluence and stock chassis-specific parts. A roadside fix keeps the box rolling to the DC instead of dead on a connector ramp.
The inland basin bakes past 100 degrees through the long Southern California summer, and superheated pavement on the SR-60 and SR-71 grades blows tires and stresses cooling systems daily. Our techs roll with multiple steer and drive sizes plus coolant and hose. The aim is to get a rig legal and cool before the heat sidelines it for hours.
More trailers are placed out of service for brakes, lights, and structure than for anything else. What governs a commercial trailer in Pomona, California, and what an inspector is actually measuring.
Every commercial trailer must pass a documented periodic inspection at least once every 12 months against the federal minimum standards, and the record has to be retained. The inspection covers brakes, coupling, frame, lighting, suspension, tires, and wheels — it is not a formality, and a missing record is its own violation.
Roadside inspections are scored against the CVSA out-of-service criteria. Certain defects — a cracked upper coupler, a defective brake beyond the allowed count on an axle, an inoperative required lamp pattern — stop the trailer where it stands until repaired. That is why a trailer repair call is frequently an emergency call.
Federal rules set maximum pushrod stroke by chamber size, and an inspector measures it rather than judging by feel. A trailer with too many defective brakes on an axle is out of service regardless of how it drives, and automatic slack adjusters do not exempt anything from the measurement.
Federal regulations specify exactly which lamps and reflectors a trailer must carry and where retroreflective tape must run. Degraded or missing conspicuity tape is a routine citation, and it is also the single cheapest night-visibility improvement on the equipment.
Trailers must carry a rear impact guard meeting federal strength and labeling standards. Damage to the guard is treated as a structural defect, and a repair weld has to restore the rated strength rather than simply close the gap.
The person performing a periodic inspection and the person doing brake work both have to meet federal qualification standards. A repair signed off by someone unqualified does not satisfy the requirement, no matter how good the work was.

Most Pomona calls are answered in about 41 minutes. You get a real time before anyone rolls, and the price before the work starts.
Pomona sits at the eastern hinge between Los Angeles County and the Inland Empire, where SR-57, SR-60, SR-71, and I-10 braid together into one of Southern California's densest freight knots. Port of LA and Long Beach drayage rolling east meets Inland Empire warehouse freight rolling west right here, and the four-freeway interchange cluster makes Pomona a perpetual breakdown and recovery hot spot.
Pomona is a city in the San Gabriel Valley of eastern Los Angeles County, California, United States. At the 2020 census, the city's population was 151,713. The main campus of California State Polytechnic University, Pomona, also known as Cal Poly Pomona, lies partially within Pomona's city limits, with the rest being located in the neighboring unincorporated community of Walnut Islands.
Pomona's location at the intersection of SR-57, SR-60, SR-71, and I-10 puts it in the middle of one of the most punishing freeway knots in Southern California, where eastbound port drayage and westbound Inland Empire freight collide all day long. Road Rescue Network's Pomona rescuers run this interchange cluster constantly and know every safe pullout in the maze of connector ramps. Average response time here beats what most networks manage in a corridor this congested.
Anyone who's dispatched a truck through the 57/60 confluence knows the merge zone is where overloaded rigs grind their brakes and overheat in stop-and-go heat that bakes the basin past 100 degrees in summer. Pomona breakdowns skew toward cooling failures, brake fade, and worn drivetrain components beaten down by relentless low-speed crawling. Our network is staffed by techs who carry coolant, brake, and air-system parts and treat the 57/60 like the home turf it is.
When a Class 8 truck breaks down on the SR-60 Pomona Freeway near the SR-71 split during the afternoon backup, every minute it sits ripples across both the port and Inland Empire schedules feeding through it. Whether you're a drayage operator hauling a container east or a fleet running dry vans out of a Chino warehouse, the nearest verified, insurance-current Road Rescue Network rescuer is one phone call away. Dispatch, ETA confirmation, and CHP coordination for the connector ramps are handled by our 24/7 operations team.
Reviews collected from fleet customers and drivers after completed service calls in this metro.
“Cooked my brakes crawling through the 57/60 with a loaded container. Tech reached me on the connector shoulder in 38 minutes, got the slack adjusters and a glazed shoe sorted, and I made the IE warehouse same day. Knows that interchange cold.”
“Truck went down on the SR-71 split at rush hour. RRN coordinated with CHP and had a heavy wrecker threading the ramps in under an hour. Operator knew exactly where to stage. Saved us a brutal night.”
“Blew a drive tire on the 60 in 104-degree heat. Service truck had the size and got me legal in about 40 minutes. One star off only because the first ETA slipped a bit, but they kept me updated the whole time.”
It depends far more on what failed than on the trailer. Lighting, air line, and glad hand repairs are typically the cheapest calls on the board and often finish in under an hour. Brake adjustments are quick; a full reline with drums across a tandem is a substantially larger invoice. Landing gear and crossmember work is billed on welding time and sits in between. Every Pomona mobile call also carries a service-call charge for bringing the truck and the parts to the trailer — which is still normally less than towing the trailer to a shop and losing it for several days. Ask for the diagnosis and the repair quoted separately so you can see which is which.
It is a load-distribution guideline: put roughly 60 percent of the cargo weight in the front half of the trailer and 40 percent in the back half, so the weight sits ahead of the axles and keeps positive tongue or kingpin loading. Load it backwards and the trailer sways, and on a commercial combination it also shifts weight off the drives and onto the trailer tandems. It is a rule of thumb for stability, not a legal standard — federal axle limits and posted bridge weights are the rules that actually get enforced, and a seized slider can put you over one of them without a single pound being added.
Usually yes, and more often than owners expect. Trailers have no engine, no transmission, and no emissions system, so the expensive failure modes that retire a tractor do not exist here — a 20-year-old van trailer with a sound frame and a good upper coupler is worth repairing almost indefinitely. The honest cutoffs are structural: widespread crossmember rot, a cracked or delaminated upper coupler, or frame rail corrosion that welding cannot restore to rated strength. Brakes, lights, landing gear, suspension, and flooring are all wear items with straightforward economics. Get an honest structural assessment first, because that is the one answer that changes the decision.
Heavy-duty parts distributors across the Pomona metro carry trailer lighting, air, brake, and suspension components, and most commercial trailer manufacturers support regional parts networks. In practice the faster route for a stranded trailer is a mobile repair truck that already stocks the high-frequency failures — lamps, harnesses, glad hands, air bags, slack adjusters, brake chambers, and landing gear components — so the repair happens on the first visit instead of turning into a parts run. Structural and floor materials are usually carried on the welding rig for the same reason.
Most of it happens on the road. Landing gear, air leaks, brake work, lighting, ABS faults, suspension components, bearings, and floor patches are all routinely done where the trailer sits in Pomona — with a welding rig for the structural half and air tooling for the brake half. What genuinely needs a shop is major frame straightening, full floor replacement, large body and panel rebuilds, and paint. The deciding question is usually not the repair but the location: a live interstate shoulder gets stabilized and towed, while the same failure in a yard or at a dock gets fixed in place.
Brakes lead by a wide margin — defective brakes beyond the permitted count on an axle, or pushrod stroke past the limit for the chamber size, which an inspector measures rather than estimates. After that: a cracked or shifted upper coupler or worn kingpin, inoperative required lamps, tires below tread depth or with visible cord, a damaged rear impact guard, and structural cracks in frame members. An out-of-service trailer cannot legally move until the defect is corrected, which is why these turn into emergency dispatches — the driver, the tractor, and the load are all parked with it.
Average response time in Pomona is 41 minutes for mobile truck repair, closer to 28 minutes near the SR-57/SR-60 confluence off-peak, and longer during the heavy afternoon backup. We post real tracked averages, not marketing numbers.
Yes, the 57/60 confluence is one of our most-frequented service zones. Working its connector-ramp shoulders safely requires CHP coordination, and our dispatchers handle that handoff so the tech can focus on the repair while traffic is managed.
Every Road Rescue Network rescuer in Pomona carries current general liability, automobile liability, workers comp, and where applicable garage-keepers coverage. We re-verify each renewal cycle, and expired insurance means automatic suspension from dispatch.
Yes. We service national accounts with consolidated invoicing, fleet-card billing, and a single point of contact. Most fleets onboard in under 48 hours through the form on this page or our dispatch line.
24/7/365. There is no after-hours surcharge in our network. Rescuers quote the same rate at 3am as at 3pm, which matters for the night drayage running through the Pomona corridor.
We dispatch routinely to the TA on Milliken in Ontario, the Pilot and Petro on Guasti Road, and the Love's in Fontana, all on the I-10 just east of Pomona. Our service trucks know the Inland Empire freight belt and these stops by sight.
Most DPF regen issues we resolve roadside with a forced regen and a cleaning of the differential pressure sensor. Full DPF removal and cleaning happens at a partner shop. We tell you upfront which path we're taking.
Standard service-call dispatch fee runs $165-245 in the eastern LA County and Inland Empire area depending on time of day and interchange congestion. Heavy-duty towing starts around $485 for in-area moves. We give a confirmed quote before the truck rolls.
Yes. Several Pomona rescuers run fleet-PM programs with scheduled visits to your yard or terminal, including the brake and cooling inspections that matter most for trucks working the 57/60 crawl. Tell us your fleet size and DOT cadence and we'll match you with the right shop.
If we determine on-scene that the truck can't be fixed roadside, we coordinate the tow with one of our heavy-duty network rescuers. In the freeway-knot interchanges around Pomona we often dispatch a wrecker alongside the service truck so there's no second response time.

Pomona runs about 153,266 people and sits in Los Angeles County, inside the Greater Los Angeles. We take the call, find the closest crew that actually does this work, and tell you what it costs before anyone turns a wheel.

Three steps from the call to a cleared scene. Same flow whether you call from a fleet desk or the shoulder of an interstate.
Trailer type, what failed, and whether there is freight aboard. A landing gear, an air leak, and a wheel-off are three different trucks — sending the wrong one to a Pomona yard costs a whole dispatch.
Structural work goes to a mobile welding rig; brake and air work goes to a truck with air tooling and brake stock. A Pomona technician who arrives without what the failure needs has to leave and come back.
Brake stroke measured, required lamps confirmed, and any out-of-service item cleared before the trailer moves. If it cannot be made legal where it sits, we tow it in Pomona rather than send a driver out on it.
Network rescuers accept all major credit cards, fleet cards, and consumer payment apps. Confirmed at dispatch.
