If I do a 2 inch shackle and spacer lift will a get vibes if I put a one inch trans case drop on

 

Every cherokee seems to be different on this subject. I would install the lift, drive it, and see if there is any vibration. If so install the TC drop. I've known people (including myself) who have lifted their jeep 4+" without a TC drop and seen no vibration.

 

Sure, you could if your u joints aren't fresh.

But typically you wont. Shouldn't need that drop either.

 

no TC drop. You shouldn't get vibes at 2" but if you go grab a 2 degree angle shim for the rear leafs.

 

Installed rusty's aal bb 2 weeks ago and developed death wobble tonight. Will be diagnosing this weekend. Just an fyi.
