Well I am sure that this is a beaten topic but search has helped littl,I pulled my t-case shifter boot the other day to take a test drive so I could see my driveshafts trying to track down a noise.I found it ,when I acelerate from a stop in first and especially in second my t-case jumps around side to side and the shifter slapps around enough to make a slapping sound.I have all new trans and t-case bushings.Mighty kong t-case mount.But I mena it jumps around like crazy.I have the toy rear end so I know about the compund angle,and I also have the missing links with the yj's in the rear.I amy be answering my own question but will a trac bar solve this is the rear axle twist prob I have been hearing about with the rear missing links or is it the compound angle rear driveshaft prob.I have not been able to get any one over hear to watch the rear end as Itake off and it does it WORSE in second gear coming out of first right before I am ready to go into third on the street.Sorry about asking a stupid newbie question but my search for....trans shudder,trans vibration,t-case shudder,transfer case vibration.......all came up with pretty much other stuff

I have a similar set up and had a problem with vibration too. The poly t-case mounts solved the t-case vibration, but the tranny continued its wiggling around. I looked around and found I had broken motor mounts (VERY common), so I put in new ones. This solved the tranny vibration problems for me. May be worth a look.

my transmission shifter was bouncing around a lot but i just thought it was supposed to do that:confused: so i never thought anything more about it, i did get pretty crazy on my zuk in moab and it started to do the first gear wobble after moab. i decided to pull the hood off for another problem and i had to drive to checker to get some misc crap for a friend hoodless and let me tell you i was surprised to see my engine doing the macarena in the engine bay. engine mount on one side really broken. i did the plymouth valiant motor mounts and all is well. no more macarena tranny!!:flipoff2: :flipoff2: :rolleyes:
