What to take off next to stop TC vibration??

[Triman]

I started the below thread while upgrading the springs and shocks with a Rusty's 4" lift kit. After installing the kit, I drove it to a local shop to have the alignment worked on and noticed a lot of vibration from the back end.

Setup is this, it had a 2" body lift and the shackles did not look like default shackles before the lift. Should I take go smaller with the shackles or remove the body lift to see if they help with the vibration?? The rear leaves have the shim installed BTW.

I see several articles about getting a CV drive shaft, but seeing if there is a cheaper option until I can drop some cash on the CV...

Thanks in advance for the info.

Don't think that the body lift has anything to do with the vibration. I am assuming that the vibration started after the lift was installed. Although more on a CJ5 than a CJ7 , due to the shorter wheel base, a Transfer Case lower of 1 inch is needed. Sort of defeats the purpose of a lift, the C.V. joint is the correct way of doing things. Have you tried the rear leafs without the shim? On my 5 it is better without. My father in laws 5 has a 4" with nothing at all and has no vibration, probably because it only has 60K. Mine was horrible!
