I was wondering why my xj vibes only when giving it gas seems like its from the rear, If you let off the gas it stop vibrating bought it with 7.5 inch lift has t case drop and sye kit and cv drive shafts. I'm wondering if there too short or long here's pictures of front and back shafts.

That driveshaft looks like it's fully compressed. Ideally it should be extended just a little bit, maybe like 3/4 inch or so.

That's what I was thinking too. How could I make it work with that shaft? Or should I get a
Stock shaft.

get rid of the t-case drop
it says to when you instal a sye
it will also stretch the ds out a lil bit

Alright will do thanks

make sure the pinion angle is lined up right. Do you have a picture from the side for the differential. You might need different degree shims to angle the axle up higher.

I can get some pictures of it tomorrow.And the rear end does sit angled down more than my 93 with 5 inch lift did with just a tc drop. I think taking the drop out will fix it.

Make sure the pinion is lined up like the following picture once you get take out the tc drop. When it is is not lined up correctly it causes vibes.



Here is some info on how to measure the angles and make sure they match up right...if they don't then you have to adjust the axle with degree shims:

Alright so I Found out that Transfer case drop helps out more than it hurts it. Here's some pictures of the angles

omg that diff angle is way off!

gvns8

woooow. haha that looks horrible. Its pointed way to high upward...you might just be better off cutting off the spring perches and rewelding them at the correct angle... or take out the shims... or add shims that make it point lower downward.
