1994 Cherokee xj 4.0
175k miles
3.5" lift
No sway bars
Stock tranny, tc, and driveshafts.
So, I recently installed a new motor and re-installed the tranny. When re-installing the driveshafts I made no effort to mark them installed them back. Driving around the neighborhood (not chancing road speeds) it shakes and vibrates pretty bad. Very noticeable. Let off gas while coasting downhill and problem didn't change. Seems to be the worst between 10-15 mph.
I'm guessing I have multiple issues here given the other problems I've had. I know it has no sway bars (front or back) and a couple of the shock bushings are failed up front. I'm thinking this issue is coming from the transfer case, u joints, or driveshafts.
I'm going to pull off the front driveshaft and see what happens on a road test. If no change, I guess I could pull the rear driveshaft and drive in 4hi to test that. Any other ideas?
I'm going to remove the front shaft then check this post.
I have old mud terrains with flat spots on it now. It's hard to diagnose road noise from car noise. Maybe jacking up rear and driving in place would help? I don't have street tires to swap.
As already noted in another thread, I have a tendency to reinstall things incorrect. It's possible I did that here. Not ruling anything out. You guys were awesome in helping me diagnose my transmission install screw up! Thanks in advance!
