Semi Trailer Repair & Trailer Mechanics in Phoenix, AZ

Trailer Repair for Phoenix Carriers and Owner-Operators

A trailer problem can shut down a load just as fast as an engine failure. Emergency Roadside Truck & Trailer Repair fixes semi trailers at our shop at 315 E Pioneer St in Phoenix and on-site with our mobile repair units, so a bad air bag, a failed light circuit or a broken landing leg doesn’t cost you the delivery.

Trailer Problems We See Most in Phoenix

Heat and long highway miles take a toll on trailers. The most common calls we get are air bags and leveling valves that fail and drop the trailer, hub and bearing failures, brakes out of adjustment, damaged light circuits, and trailers tracking to one side because of worn suspension parts or a bad alignment. Catching these during a scheduled inspection is much cheaper than a roadside failure.

Trailer Pre-Trip Checklist

• Check tires for pressure, cuts and uneven wear.
• Look at air bags and suspension for leaks, cracks or a trailer sitting low.
• Check hubs for oil leaks or excessive heat after a run.
• Make sure landing gear cranks smoothly and is fully raised.
• Confirm brakes are adjusted and slack adjusters are within limits.

Trailer Repair for Fleets

If you run several trailers out of Phoenix, we can inspect and repair them at your yard on a schedule so problems are caught before they cause a roadside failure or a failed DOT inspection. Ask about combining trailer service with our fleet maintenance program.
