Trailer alignment and dog-tracking

If the trailer runs off-line behind your truck or wears its tires unevenly, call with the axle setup so we can check what your unit needs.

When the trailer runs off-line

Look for uneven tire wear, a trailer that pulls to one side on a straight road, or changes after an axle impact or suspension repair.

Worn bushings, shifted mounting points and bent components can all affect how a trailer tracks. An inspection helps narrow down the cause.

What is dog-tracking?

It’s when a trailer runs to one side of the tractor’s path on a straight road. Axles that sit out of square can contribute, and a shop inspection can confirm the cause.

What information should I bring?

Have the trailer type, length, axle configuration and tire positions affected. Tell us whether it has had recent suspension work or hit a curb.

Call with the trailer’s axle setup

Have its length, axle count and the tire positions showing wear handy.
