I just had a RE 3.5 inch lift put on my Cherokee (2001, 4.0L Auto) The guy that installed the lift also did a AA SYE kit and a new Wood's Driveshaft for me. But he also left the TC drop on it from my other lift the was on the Jeep. Is there a benifit in doing this? Can I remove the TC drop and be ok? When I first picked up the Jeep there were no vibes at all. Now I have very slight vibes around 30 and 50 or 55 mph. Am I getting vibes as my rear springs are settling? Other than that I love this lift great flex and ride, well worth the money!!! I got the lift from www.4x4groupbuy.com Jason is a great guy to work with if you need something send him an e-mail
