Just got some bad news. I took our motorhome in because the tires are wearing on the edges. The tire pressure is correct and the front end is OK. It turns out the all the rear axle bushings are wore out causing the vehicle to dog walk. So now they have to order the parts and it will take two days labor to replace. They told me the bushing killer is, not using the vehicle. They dry rotted from sitting. We have a trip setup for next week to attend the Dream Cruise so I'm hoping they will have it completed in time. Just wanted to let people know what can cause the tires to ware on the edges. All well, it could be worse. Have it break down on the road.Happy Camping, bye Dennis:(

Never heard of bad bushings in the rear suspension causing front tire wear. I guess you learn something new everyday. I would have guessed it was a toe-in/toe-out problem.

Yes thats what I thought the problem was with the alginement. The rear axle had moved back 3 inchs on the left side causing it to dog walk and pushing the front of the vehicle to the left. It didn't drive goofy or any handling issues. Now than you could hear clunk when you hit a pot hole. Other than the tire wear everything acted and looked fine. I'm just happy that they found it. It's going to cost $5000.00 to fix it, but it should drive like it was new.Happy Camping, bye Dennis

Can't imagine how a bushing could cause the rear axle to shift 3"...Then $5,000 to fix it???...I would for sure get a second opinion...This smells a little like snake oil to me.B.O.

I thought most bushings on modern vehicles were made of brass or some other metal. How can metal dry rot? Maybe lube dried out for metal to metal contact and excessive wear?

The only bushings that have anything to do with rear axel are the leaf spring eye bushings, which are brass. They can not cause an axel to move 3". You would really notice an axel that was out 3" on one side. Not sure you could even drive it. That would cause alot of problems with the drive shaft, maybe even coming out! You sure that is what they told you? Sounds like some other problem.

Unless someone has the exact same unit, we can only guess about the bushings. I would like to see a photo, 3" doesn't seem possible, but I can't see it from here.
