I have been having some really bad vibrations from something in my Jeep. Today I got the tires rotated and balanced which I had hoped was the problem. Still vibes.
Hub bearings are good, u-joints are good, ball joints are good, driveshafts don't have play.
It is not transmission or engine related. Happens between 45-50mph and at 65.
What else could cause something like this?

 

ive got the same problem, happens between 45 and 60 for me. all my stuff is good to. if you find the cause let me know

 

if u guys are lifted try doing a tc drop.

 

any lift over 3" will give you horrible vibes from the rear drive shaft... a TC drop or sye will fix this problem

 

45-50 mph sounds like tires need balanced. Just my two cents. Not a lot of info. Is the vibes in the front or rear and where can you feel it? in the seat, steering wheel, rear? I would start with tires balanced. Also any recent changes.

 

See the second sentence of my post. Got them balanced today. The entire jeep vibrates, its so loud I can hear some interior trim rattling from the vibration.
I'm going to try pulling the front driveshaft, if it fixes it get a new one, same with the rear driveshaft. The only thing I can think of that would cause it is an unbalanced driveshaft.

 

Well with having no lift and good balance with the tires. The D/S sounds the only other logical step. I'm not to familiar with veh. D/S so i'm not sure if the is some type of weight used to balance them. Possible the weight flew off of the D/S is dented some where. Please let me know the outcome.
