Truck, Semi-Truck & Trailer Repair in Mercer, PA

What Is Truck, Semi-Truck & Trailer Repair?

Truck, semi-truck and trailer repair is the work that keeps a tractor-trailer rig safe and rolling as one unit. On the tractor, it covers the brakes, the fifth wheel, the suspension and the connections to the trailer. On the trailer, it covers axles, brakes, lights, doors, floors and landing gear.

A rig is only as good as its weakest part, and a trailer problem stops a load as fast as an engine problem. We inspect both halves of the rig and repair what is worn or broken. Then we test the brakes, the lights and the air system before the rig leaves.

Why Semi-Truck and Trailer Repair Matters in Mercer, PA

Rigs that pass through Mercer run some of the busiest freight corridors in the region, where I-79 and I-80 cross in Mercer County. Long interstate miles wear trailer brakes, wheel bearings and tires. A worn part on a loaded trailer can cause a blowout, a fire at the wheel end or a brake failure.

Winter here is hard on trailers too. PennDOT's District 1, which covers Mercer County, used over 98,000 tons of salt on its roads in one winter. That salt eats at trailer wiring, light plugs, brake parts and frames, so they fail sooner than they would elsewhere.

When to Consider Semi-Truck and Trailer Repair in Mercer, PA

Call when the rig changes: lights that flicker, air you can hear leaking, a trailer that pulls, or a door that will not seal. Each of these can turn into a roadside stop or a failed inspection. Fixing it early costs less than fixing it after it gets worse.

After winter is a good time to have trailers checked in Mercer, once the salt has done its work. Before a long run, a quick check of brakes, lights and tires is worth the time. Trailers that sat for a season deserve a look before they go back on the road.

Trailer Brake, Axle and Suspension Repair

Trailer brakes carry much of the work of stopping a loaded rig. We repair air lines, brake chambers, slack adjusters, drums and shoes. We also replace wheel seals and bearings before they fail and take the hub with them.

Axles and suspensions carry the load and keep the trailer tracking straight. We repair air ride systems, springs, bushings and torque arms. A trailer that tracks true is easier on tires and easier to drive.

Trailer Doors, Lights and Landing Gear

A trailer door that will not close leaves a load exposed and a driver stuck. We repair swing doors, roll-up doors, hinges, rollers and latches. We have fixed sliding doors on semi trucks right at the customer's location.

Lights and wiring keep a rig legal and visible. We repair light plugs, harnesses and grounds, and we fix landing gear that is stiff or bent. Our Truck Electrical System Repair service covers deeper wiring faults.

Tractor Repair for the Rig Up Front

The tractor needs the same care as the trailer it pulls. We repair the fifth wheel, the glad hands and air lines, and the brakes and suspension under the cab. For engine and drivetrain work on the tractor, our Heavy-Duty Truck Repair service covers it.

Working on both halves of the rig in one place saves a trip. We can also do a DOT inspection on the tractor and trailer together. That way the whole rig leaves ready to run.
