Professional Trailer Repair—Mobile and In-Shop Service for Arizona Truckers

A broken trailer can shut down your schedule, throw off delivery windows, and cost thousands in missed freight revenue. Cornwell’s Truck Repair understands that every minute you’re down, someone is losing money—and usually it’s the driver. That’s why we deliver a true mobile trailer repair service that comes straight to your breakdown site, 24 hours a day, 7 days a week.

Whether you’re sitting on the shoulder outside San Simon, parked in a rest stop near Tucson, or stuck along I-10, I-8, or US-70, our certified roadside techs respond fast and perform most repairs right there at your rig—without forcing a tow.

We repair:

• Dry vans
• Reefers
• Flatbeds
• Drop decks and step decks
• Tanker and hazmat trailers
• Agricultural trailers
• Heavy-haul and lowboy trailers

When the repair requires welding, axle service, or fabrication, we tow you to one of our shops and turn the job quickly.

Truckers run Arizona because freight moves fast through deserts, ports, border crossings, and long-distance highways—but it’s also a harsh environment. Heat, vibration, dust, and long grades are frequent causes of:

• Electrical shorts and trailer light failures
• ABS system errors and sensor failures
• Air system problems and suspension leaks
• Brake wear due to desert heat
• Landing gear damage from loose gravel lots

Cornwell’s supports truckers who travel major freight routes:

San Simon, Tucson, Eloy, Gila Bend, Marana, Oro Valley, Avra Valley, Nogales, Lordsburg, and Yuma—plus the NM border and the I-10 long haul.

If you’re loaded, overweight, late to a pickup, or carrying a high-value shipment, we get there fast so you can stay compliant and moving.

Mobile Trailer Electrical, Lighting and ABS Repairs—24/7

One of the most common calls we receive from OTR drivers involves electrical and ABS trouble. Traffic stops, DOT checks, or secure-facility entries can instantly fail you if a brake light or ABS module is out.

We diagnose and repair:

• ABS faults and warning lamps
• Wiring harness failures
• Broken plugs and 7-way connectors
• Intermittent electrical shorts
• Side marker and tail light issues
• Reefer trailer electrical support
• Corroded wiring and terminals

Most repairs are done roadside. If the system needs shop programming support, we tow you quickly.

Trailer braking systems suffer in extreme heat, long gradients, and stop-and-go border-area traffic. Our mobile mechanics handle:

• Brake chambers
• Brake shoes and drums
• Air valves and airline leaks
• Slack adjuster issues
• Wheel seals
• Hub and bearing concerns

A leaking air system can turn into a complete shutdown—and that’s why Cornwell’s arrives with the parts, fittings, hoses, and diagnostic tools needed to fix air leaks roadside whenever possible.

Landing Gear, Structural and Mechanical Trailer Repairs

Landing gear failures can prevent drop-offs, cause injury, or damage a yard. We routinely assist with:

• Bent landing gear assemblies
• Crank and gearbox issues
• Support bracing
• Weld-in repairs
• Replacement legs

If your trailer came down hard or twisted under weight, we evaluate structural integrity and guide the safest repair.

Some trailers need more than a quick fix—they need the type of heavy work only a shop environment can provide. Cornwell’s brings you into our facilities for major repairs such as

• Roof patching and skin replacements
• Floor and crossmember repairs
• Panel rebuilds
• Swing door rebuilds
• Frame and mounting reinforcements
• Suspension replacement
• Axle, kingpin, and alignment support

This is especially important for fleets where mechanical integrity equals insurance compliance.
