Semi truck suspension repair should begin with diagnosis, not with replacing the first worn part we see. A rough or bouncing ride, a truck or trailer that leans or sits low on one side, clunking over bumps, an air leak you can hear, or tires wearing unevenly can all point to the suspension. Similar symptoms can also come from tires, wheel ends, steering parts or alignment, so we look at them together.
At Truck Pit Stop, the process starts with the driver’s complaint, the ride height and the tire-wear pattern. Technicians then inspect the suspension and the parts around it before recommending work. If we find something that has to be fixed first, we document it and explain the options before proceeding.
We work on suspension for semi trucks and semi-trailers. Common jobs include air bag replacement and trailer leaf spring replacement. Because worn suspension parts can change how an axle sits and tracks, suspension work is often followed by an alignment check, and irregular wear may also need tire service.

Common signs include a rough or bouncing ride, the truck or trailer leaning or sitting low, clunking over bumps, an air leak, the air compressor running more than usual, irregular tire wear and changes in handling. Because tires, wheel ends and steering parts can cause similar symptoms, the cause should be inspected before parts are replaced.
Depending on the truck or trailer, it can include air springs (air bags), shock absorbers, leaf springs, hangers, U-bolts, bushings, mounts, height-control valves and air lines. We inspect the related steering, wheel-end and tire condition at the same time.
It depends on what is wrong. A leaking air spring, a broken spring leaf or loose mounting parts can affect control and stability and can also cause problems at a roadside inspection. If you notice a change in ride height, handling or noise, have the suspension inspected as soon as you can.
Most repairs are finished the same day. If a job needs parts ordered in, or your truck arrives near closing, we finish it first thing the next business morning. If a part will take longer, we’ll tell you upfront.
It depends on what the inspection finds and which parts are needed. Our labor rate is $120 per hour, with parts quoted separately, and we give you an estimate and get your approval before any repair begins.
Yes. Worn suspension parts can change how an axle sits and tracks, which can cause irregular tire wear and handling complaints. After replacing parts that affect axle position, an alignment check is often recommended.
