Inner Tire Wear of Only One Tire

[texasvet]

This is my first post to this forum. I purchased a used 08 XLR 30x12 that has dual axles. I noticed that the back drivers side rear axle tire is worn on the inside only. The other three tires are without problem and are wearing evenly. Wanted to get some advice as to what I need to check and whether I'm looking at an axle replacement or not. Thanks.

My gut instinct is to check the bearing. If it's bad the entire hub could be leaning inboard causing the wear you see.

I agree, and if that is not the cause, the spindle or axle is bent on that side which will require replacement.

Appreciate the advice. So if the spindle is bent can these be replaced the same as a vehicle or does the entire axle have to be replaced? I hope to do some general checks today and will have to determine a method to see if the spindle is bent.

Don't know what your axle looks like, but it is doubtful the spindles are replaceable. Take the tire/wheel/drum off and take & post some pictures.

An easy way to check:
- Lift and support that side of the trailer, do not lift under the axles
- grab the top and bottom (12 and 6 o'clock) of the worn tire and try to rock top to bottom
- grab the front and back (9 and 3 o'clock) try to rock left to right.

If no noticeable movement, it may be a bent spindle/axle.
If it moves noticeably, bad bearing.

Another method would be to check with a straightedge and ruler. Check the top and bottom of the "good" wheel on that side and compare with the bad wheel. This is not fool proof as the axles can be adjusted individually.
