sounds like an alignment issue.

alignment.

it's common for the inside to start cupping.

i have the same problem that's now starting to cause the truck to vibrate. 35000 miles on new recaps

thats about what i was thinking..whats around about price for all wheel alignment

Axles just don't go out of alignment without a reason. If this tire wear has been on-going for weeks, then maybe all you need is and alignment. If this happened rather sudden something else is wrong like worn out bushings or something broken back there.

Your wheel bearings could be loose.

guessing by his username he does some off road driving. its not uncommon for alignments to get knocked out in off road applications. this is what id put my money on.

yah, maybe you've done it but take a close look at the springs and U-bolts. as quick as this problem came on you may have a broken spring or your u-bolts have come loose on one axle. you can usually tell if the u-bolts are loose because there will be a rust mark where they normally sit on the spring. broken spring you will see the crack.
