Improving rear suspension ride quality

[AZ XJ]

Also: 30 pounds in 32s is pretty high pressure for an XJ. I run 30x9.50s at 30 lbs and it's about right... try dropping to 28 or 26. Chalk line it to be sure - maybe BFGs need more air than my coopers - but 30 sounds high to me.

I've experimented with tire pressures some, and can confirm that lower pressures do improve the ride, but 30 is the best compromise I could find between ride/milage/wear.

With the shackle relocation brackets on, what angle/degrees should the shackle be?

45 degrees is ideal, anything other than vertical will be an improvement.

don't forget the obvious, make sure your shackle bolts aren't too tight, you should be able to spin them with a wrench pretty easily

uh, yeah, and what those other guys said too
