Trailer Repair Near Me — Mobile Welding & Structural Repairs
Expert structural repairs and custom welding for all trailer types.
From minor weld repairs to major structural work, our certified welders handle all types of trailer repairs. We work on dry vans, flatbeds, reefers, tankers, and specialty trailers. Our mobile welding capabilities mean we can perform most repairs wherever your trailer is located.
Trailers take a beating on every mile of highway—road vibration, shifting loads, corrosion, and impact damage all take their toll on structural integrity. A cracked crossmember, damaged landing gear, or broken ICC bumper does not just put your trailer out of service; it puts your DOT annual inspection compliance and your CSA score at risk. Weldon's Truck & Trailer provides expert trailer repair and mobile welding services from Kingman, AZ, serving CDL drivers and fleet operators across a 200-mile radius. We perform MIG welding, stick welding, and aluminum welding on every trailer type including flatbed trailers, dry vans, reefer units, step deck trailers, lowboy trailers, tanker trailers, and specialty equipment. Our certified welders bring professional-grade steel fabrication and welding rigs to your location for on-site structural repairs that meet DOT and FMCSA standards.
Detailed Trailer Repair & Welding Services
Our trailer repair capabilities cover everything from minor cosmetic fixes to major structural rebuilds. We perform MIG welding, stick welding, and structural welding on steel and aluminum trailers, repairing cracked crossmembers, damaged subframe members, trailer flooring, bent side rails, and rusted-out support structures. We repair and replace landing gear assemblies, glad hands, air lines, and brake chambers to restore full braking function. Kingpin and fifth wheel coupling repairs ensure safe connections between tractor and trailer. Our technicians rebuild and replace S-cam assemblies, brake drums, and spring brake components on trailer axles. We fix roll-up door and swing door mechanisms, repair door hinges, and address roof repair damage from low-clearance impacts. We also handle DOT annual inspection preparation, repairing any deficiencies—including ICC bumper replacement, reflective tape application, mud flap replacement, and trailer lighting repairs—so your trailer passes inspection the first time. For reefer unit trailers, we address structural damage to the refrigeration compartment and door seals to maintain temperature integrity.
What's Included
Common Trailer Problems We Fix
The most frequent trailer repairs we see involve cracked or broken crossmembers from overloading or road impact, landing gear failures from corrosion or hydraulic seal leaks, and glad hand connection issues that cause air brake malfunctions. Worn S-cam bushings and out-of-adjustment brake chambers are common findings during DOT annual inspections. We also regularly repair damaged ICC bumpers, replace worn air lines, fix trailer door hinges and latches, and address rust damage to flatbed decks and dry van floors. Step deck trailers frequently need ramp hinge welding and deck plate repairs. Our welders carry the materials and equipment to handle these repairs on-site, whether your trailer is at a shipper's dock, a truck stop, or on the roadside.

Trailer Maintenance & Preventive Inspections
Preventive trailer maintenance reduces roadside failures and keeps your equipment out of the shop. Our technicians perform comprehensive trailer inspections covering the frame, floor, doors, lighting, brakes, and running gear. Routine service includes greasing fifth wheel plates and kingpins, adjusting slack adjusters, checking brake stroke measurements, lubricating landing gear assemblies, and inspecting tire condition on all trailer axles. Catching a cracked crossmember or a leaking brake chamber during a maintenance visit costs far less than an out-of-service roadside breakdown or a failed DOT annual inspection.
Trailer Hitches, Kingpins & Fifth Wheel Connections
The coupling system between tractor and trailer is a critical safety component. A worn kingpin that exceeds FMCSA measurement limits will immediately fail a DOT roadside inspection and is a serious accident risk. We measure kingpin wear using calibrated gauges and replace pins when they exceed service tolerances. Our technicians also inspect trailer hitches, fifth wheel jaw engagement, and coupling locks on specialty trailers — covering drop-deck, lowboy, and heavy-haul pintle hitch configurations in addition to standard fifth wheel couplings.
Major Trailer Repairs vs Minor Repairs — Field Triage
Not every trailer problem requires a full shop visit. Our technicians assess damage on-site and determine whether the repair can be completed in the field or requires a facility. Minor repairs — broken door latches, loose marker lights, glad hand replacements, brake chamber swaps, and small floor patches — are almost always completed in one visit. Major structural repairs like full crossmember replacement, bent main rail straightening, and tandem slider track rebuilds may require a shop setting, but we always maximize what can be done in the field to minimize your downtime and towing expense.
Trailer Brake Service — Chambers, Slack Adjusters & Air Lines
Trailer brakes are a primary DOT inspection point and a direct contributor to stopping safety on Arizona's mountain grades. We replace brake chambers, spring brake actuators, slack adjusters, S-cam assemblies, brake drums, and brake shoes on trailer axles. Air line replacements — glad hands, hose assemblies, and glad hand seals — restore proper air delivery to the trailer brake system. After every trailer brake service we perform a brake stroke measurement and apply-release test to verify the system functions within DOT specifications before the trailer returns to service.
Trailer Body Repair & Panel Restoration
Dry van wall panels, reefer compartment liners, and flatbed side rails take constant abuse from loading equipment, shifting cargo, and road debris. We repair cracked or delaminated wall panels, patch damaged side boards, restore bent stake pockets, and fix door frame damage that prevents a square close. Body repairs are performed on-site using appropriate adhesives, fasteners, and structural reinforcement materials for the trailer type. Fleet operators can schedule panel restoration visits at their terminal or yard to keep trailers cargo-secure and professionally maintained.
Trailer Roof Repair — Low-Clearance Impact & Structural Damage
Low-clearance collisions are one of the most common sources of serious trailer damage. A roof impact from a bridge or overhead obstruction can damage roof bows, roof sheets, and door header framing — creating structural weakness and weather intrusion that damages cargo on subsequent loads. We repair aluminum and steel roof bow assemblies, patch and seal damaged roof sheets, restore door header framing, and address structural damage to side posts and rear frame corners. Every roof repair is sealed for weather-tightness before the trailer is returned to service.
