Drive Line Vibrations
 

I just had a 2 inch spacers lift installed in my 2001 TJ. It was installed by a after market 4 Wheel Drive shop. There is now some drive line vibrations. More noticeable at slower speeds. Has anyone else experienced this and what can be done to fix it?

Do you know where its coming from? Like the back or the front.

Something must be moving where it should not be.

Seems to be coming from the back. There doesn't seem to be anything loose

i put a 2 inch spacer lift in my 99tj and had no problems. if you have vibrations and they have started since the instal of the lift they are obviously a product of the lift. what is happening is your driveline is now at a steeper angle and your having issues with alignment of 'u' joints. this may happen on some lifts and not others. i would drop the tranny skid plate maybe half an inch and see how that works. just put in some spacers between the frame and skid plate mounts and see if your vibrations goes away. it should improve.

Thanks for all your ideas, turns out one of my u-points was shot and i guess the change in angles was enough to cause the vibrations.
