4" lift 03 rubicon vibrations

I just installed a 4" lift from Zone Offroad. I just had a alignment done and still when I start off till I'm about at 30 mph I feel like the front tires are fighting the pavement. It tracks fine. Also I get a on and off vibration that starts at about 45 mph and get very noticeable at 50 then around 55 it starts to go away. My guess is a driveshaft vibration for my later issue but not sure. Any suggestions?

I forgot to mention that the one vibration I feel at around 55 feels like it is coming from under the center of the jeep.

This is a Drive shaft vibration ... when you go to 4 in of lift on a tj most people need a new rear drive shaft ... The front end vibration could be caused by a few things .. Tires, a track bar thats to short , a bad u-joint in the d-shaft , or some play in the steering box ..

Did it vibrate before the lift ? If not , what parts did you change out with the lift ? Did the kit come with an adjustable track bar , adjustable upper and lower links ?

yea that one around 55mph is the drive line. your angles have changed, im dealing with that now on my 03 Rubi. Tom Woods Driveshafts seem to be the answer.

first off, when you had the alignment done, what was the caster spec?

secondly, did you install a t-case drop or CV rear driveshaft?

Did you instal a sye kit or cv shaft with the lift? If not this is most likely your problem (shaft vibration).

Maybe you should read the date of the last post and realize the thread is stale.
