i took my jeep for a test drive for first time the other day. everything seemed to be fine until i hit 54 mph it felt like the driveshaft got at a bad angle and it started thumping i got a t case drop i hope this will help what you guys think?i mean it sounds like its comeing from the drive shaft am i right?

 

Check the toe , usually right front side

 

I got this a couple weeks ago. Really bad vibration at 55 mphs, turned out to be a bad tire up front. But if you just lifted it and this started than your probably right about it being a driveshaft/Ujoint issue.

 

Depends on your height whether or not its the shaft angle. I'm running around 5.5" with a 3/4" t-case drop and no vibes

 

did you align it after the lift

 

nope dont got the money and i never aline it. it would be a waist of money the way we wheel we prob nock em out of alinment every trip.lol and also i putten a t case drop on it. its the drive shaft

 

you did adjust the toe right

 

what the toe?? my jeep dosnt have feet!! it has tires? lol no but realy what is the toe?

 

you can set the toe with a tape measure, and wheeling isnt going to knock your alignment off unless you bend something.

 

off topic...

btw, ive been noticing lately that people have a bad missunderstanding of what death wobble really is

 

i cnt do anything till i no what toe is!!!!

 

toe is you front tires pointing in or out they have to be a certain distance aprtin the fron compared to the rear you adjust it with the steering links in the front

 

you turn the tie rod one way or the other it bring the front closer together or the rear closer together

 

google how to adjust the toe on your year xj

 

and what will this do? like i mean what dose it improve?
