Hi So the tires on the rear axles on my 2003 Elite have worn badly on the inside, tires on front axle seem to have worn evenly. So I took the trailer into tire shop and had the bearings and axles checked and I am told both are fine but that I should get an alignment on the trailer. I have never head of this, if this really a thing or would I be paying for a service I don't need? Opinions? Thanks Joan

Well, they are right, and wrong. Your Elite will have a torsion axle on it, which means there is a solid steel beam bolted to the frame, and at each end a swing arm / spindle mounted in rubber- pushed into the end of the beam. Normally- trailer and big truck axles are aligned by literally bending them. But since you have that rubber connection in the middle- not possible. Dexter (a large torsion axle maker) for example clearly states "no" regarding any alignment to that product. So yes- tire wear shows a need for alignment, no- that axle isn't supposed to be aligned.
For what it is worth, oftentimes rear tire inside wear can come from a trailer that is nose high. The slope puts a higher load on the rear axle, causing negative camber causing tire wear. We have seen simply leveling the trailer may help. Otherwise, a new axle is in order.
Also however- how long did that take to happen? Generally rear tires wear worse than front, so it is the norm to rotate the tires when the bearings are packed.

Thank you for your reply to my post. My trailer does ride a little nose high, truck seems tall for it. How many inches should be allowed between the trucks bed rail and trailer to be safe? Also, I haul one horse in the rear stall and I am wondering if that also has an effect on rear axle weight. I have been told that it should't be a problem with a living quarters due to the weight of the interior conunteracting the weight of the horse in the last stall.. These tires are 4 years old. Thanks Joan

I have approximately 5.5" between the underside of the gooseneck and top of truck bed rail. No clearance issues. 2019 Ram 3500 4x4 Dually & 2015 Lakota 8411 w/slide. Fairly heavy. I'm at the last notch on the shocker hitch coupler too.

I typically shoot for about 7-8" (two fists on top of each other) between truck bed and trailer. Your terrain may require different spacing.Yes- older trailers sat lower, which is causing problems with new trucks. That's why you'll see a lot of new trailers advertised as zero degree axles, or blocked axles - all done to raise the rear end for a level ride.
