[QUOTE="backwoodsboy, post: 857338, member: 5415"] I had a truck with similar issues after swapping leafs in the rear. Static ride height the axle was completely centered. Under bump the axle would shift forward. After a whole lot of screwing around we decided that the shackle length was too long. Basically the longer shackle was increasing pinion angle right off the bat and having the shackle at the rear was causing the axle center-line to shift forward under bump. Both were contributing to bind in the drive-train. I'm sure I'm over thinking things, and you've just got a little bit of axle wrap going on, but that's how my brain work. Did you do anything to the shackles when installing the Deavers? [/QUOTE]
