I am currently having some work performed on my 2006 keystone travel trailer. During a routine bearing repacking some unusual tire wear was noted.... I asked them to replace all four tires, and look at the axel alignment. The front axel is out by one inch, the back is out 1/2 inch.... They said that they could fix the alignment issue..... My question is..... Is one inch out of alignment an acceptable amount or is it something that needs to be repaired. I understand that perfectly aligned is preferable but in this imperfect world how much slop is acceptable?

Unusual tire wear could be from different reasons.
Tire pressure would be the first.
Weight distribution on the unit second.
Next could be the axels out of alignment.
What has to be determined is the amount of wear on each tire (inside,outside,center location) and mileage on the tires.
Given you have straight axles wear is going to happen.
The question is 1 inch too much on alignment? Not enough to give extensive wear but enough to wear over time

The maximum recommended deviation is 1/8". You find many websites explaining the trailer alignment procedure. Now your issue is why/how are they that much out of alignment. Standard trailer suspension (spring hangers) is welded into place. The mfgr. should be questioned about the why/how issue- if the axles are not bent.

IMHO 1inch is WAY to much, but Im also known to be a perfectionist
I would have it fix, but also saying that I can fix stuff like that my self and not pay labor fees, so I dont know if the labor fee is in your budget

Your title should read axle alignment but I will comment on tire balance. Make sure your new tires have been balanced. Lots of shops don't think it matters but are wrong. Not balancing alone with cause rapid tire and suspension wear.
Hi Max 1 inch is to much look at your tires you be the judge. One thing you need to know is the axle bent or did they weld the mounts on wrong? You don't want to replace the axles if the mounts are welded in the wrong place. I have a friend that bought a trailer the tires were bald after about one year so I checked it out ,I should let you know that I own a alignment and repair shop. Anyway the mounts were in the wrong place I don't remember how much but he contacted the place that built the trailer and they relocated the mounts and gave him a new set of tires all is well now. If the axle is bent I think it is better to replace the axle rather than bend for the correction needed. We just took a tape to find that the mounts were off. Hope this helps.
