My vibes are getting pretty bad, just replaced rear u joints a few months ago, front drive shaft has been out.

It can be felt mostly when pressing the gas at 30+mph, especially when low in rpms, not too noticeable at 60+mph, sometimes it feels really bad like somethings gonna grenade.

The u joints feel ok and the diff yoke feels ok not much play, but at the transfer case the shaft moved up and down side to side a bit...

So... What needs done. I have decided to dump a bunch of money into the jeep to get it good and reliable and run good. About to redo all the calipers and master, rear wheel bearings, shoes, tune up. Need to get these vibes sorted.

Thanks.

 

really no comment lol?

Well I'm doin my brakes and rear end stuff today along with throwing new u joints in the drive line again since I bought the "gold" ones they have lifetime warranty and replaced for free. See if that helps any.

BTW its an aw4 and 242

 

well after I replaced the u joints and rear end stuff it does not feel too bad. drives soo much better with the stiff leaves out and lift shackles helped pinion angle a lot too.

 

I got the same problem

 

%80 of it was taken care of by correcting pinion angle, rear bearings and diff fluid, u joints, not I just changed diff and trans fluid and it feels even better. My trans mount is also shot need that.
