Well, finally got the extra axles under my hunting Jeep. 2.5" Rancho springs with new shocks, and locked stock axles with 3.31's
The ubolts came with aluminum shims for the springs, which I knew not to use, and after reading that with a 2.5" lift that shims usually weren't necessary, I opted to try things without shims.

Of course, as was pointed out in the above post, I get a nice vibration now when driving down the road.
If I push the clutch in and coast, everything is smooth as silk. Under power I start getting vibes which get pretty bad at about 35-40. I assume this means I need to shim the rear springs, and I know I should get steel shims and not use the crap aluminum ones that Rancho supplied.
So how does one figure out what degree of shim to use? To add to the irritation, I'm gonna have to get longer spring centering pins to go through the shim. Are those standard bolts or is it some specialty part?
