Suspension & Steering Repair
A truck that wanders, pulls, or rides rough usually points to worn suspension or steering components — air springs, torque rods, kingpins, or the steering gear itself. We inspect the whole front end before replacing individual parts.
Symptoms we see
| Symptom | Likely cause | What we do |
|---|---|---|
| Truck wanders or is hard to keep straight | Worn steering gear box, tie rod ends, or kingpins | Inspect steering linkage and kingpin play before adjusting or replacing components |
| Rough ride, bottoming out over bumps | Failing air springs, worn shocks, or a height control valve issue | Inspect air springs and shocks, test the height control valve |
| Clunking noise over bumps or on turns | Worn torque rod bushings, equalizer, or U-bolts | Inspect torque rods, equalizers, and U-bolts for wear or looseness |
| Steering feels loose or has excessive play | Worn kingpins, tie rod ends, or steering gear box wear | Measure kingpin and linkage play against spec |
| Uneven ride height side to side | Air spring or height control valve issue on one side | Test each side’s height control valve and air spring independently |

What the job involves
We check kingpin play, tie rod ends, and the steering gear box together, since wear in any one of these throws off the whole front end and they’re often diagnosed as a group.
Air springs, shocks, torque rods, and equalizers get inspected for wear, cracking, or looseness — these wear gradually, so drivers often don’t notice until it’s significant.
If ride height is uneven, we test the height control valve on each side independently rather than assuming it’s the same fault on both.
Steering and suspension problems often show up as uneven tire wear first — see /services/truck-alignment if that’s part of the complaint.
What drives the cost
What this costs depends on which components are actually worn, how many points in the front end or suspension are affected, and whether it’s adjustment or replacement. We tell you after we look at it, before we start.
Common questions
Why does my truck wander on the highway?
Usually worn steering gear box, tie rod ends, or kingpins. We measure play in the whole system to find the actual source.
What causes a rough ride?
Failing air springs, worn shocks, or a height control valve not regulating properly. We inspect all three.
How often should kingpins be checked?
At every major PM interval — kingpin wear is gradual and easy to miss until it’s affecting steering feel.
Does suspension wear affect tire wear?
Yes, significantly. If you’re seeing uneven tire wear, it’s worth checking suspension and alignment together.
What does a suspension repair cost?
Depends which components are worn and how many. We inspect the whole front end before quoting.

Commercial Truck Alignment
Misalignment doesn’t announce itself — it just eats tires faster than it should, one edge at a time, until a fleet manager notices the replacement schedule creeping up. We check thrust angle and toe on the whole tractor, not just the steer axle.

Tire Service & Replacement
Uneven wear, a slow leak, or a blown casing on the road — we handle tire replacement, mounting, balancing, and flat repair for Class 6–8 trucks. Wear patterns often point back to alignment, and we check that connection instead of just swapping the tire.
