Check the bearings before the axles are measured
A trailer alignment measures where each axle points relative to the kingpin and to the other axles. That measurement assumes the wheels are held firmly on their axles. If a wheel bearing has worn, or its adjustment has loosened, the wheel can move on the spindle, and the alignment reading is taken on something that will not stay put.
Loose bearings have a second effect that shows up on the tires. A wheel with excessive play can wobble slightly as it turns, and that produces irregular wear that looks like an alignment fault. Aligning the axle will not cure it.
What to look for before booking
- A wheel that rocks when gripped at the top and bottom with the axle raised.
- Grease or oil on the inside of a wheel or tire, which can mean a failing seal.
- A hub that runs hotter than its neighbors after a run, felt carefully or measured, not grabbed.
- Irregular, scalloped wear on one wheel position rather than across an axle.
Any of those is worth mentioning when you book. Bearing work and seals come first; the alignment follows on a sound assembly.
When to align a trailer
After an impact with a curb or a dock, after any axle or suspension work, when a trailer joins the fleet, and whenever the tires on one trailer wear faster than the rest. A tractor whose steer tires keep wearing after its own alignment is also a reason to check the trailer behind it.
The tractor can be done at the same visit with heavy-duty truck alignment, and several trailers can be scheduled through a fleet account. The national trailer alignment page covers what the measurement includes.
