anyone running a similiar setup???
i have a 89 4.0 231 auto 3.55's, 33's, lotsa trimming, 1 inch t case drop .....im running 3" coils/full packs. 5" lift shocks with limit straps....i recently added boomerang shackles and now have vibes. i added 6 degree shims (no sye, so the fat part of the shim faces the tcase, skinny part backward)which kicked the vibes back to about 55-60mph, but before the shackles i was going 75-85 with no vibes at all.
so im thinking about a few options:
1.adding say mj shackles(1/2 net lift) and 3 degree shims(or no shims at all?)
2.maybe i overshimmed and should try 4 degree shims?
3. replace the u joints and see if that fixes it? the joints are tight, but ive heard that they can wear a certain way and adding more lift can piss em off and make em vibe.
4. throw the stock shackles back on, pull the shims, and lose the extra rear articulation, maybe that 1" of lift aint worth the vibes?
these are my cheapest solutions.
im leaning towards mj shackles if they really do add 1/2 of lift,a nd maybe no shims?
