So I got the rear of my nightmare lift done yesterday. Was planning on doing the whole thing, but every bolt was seized into their bushings, the shocks were ghetto rigged in by whomever previously did shocks on the jeep. so I didn't have time to do the front.

Anyway, I drove it the 14 miles home with only the rear done. 3" lift with new spring packs. Actually went from 16.5" to "21" from fender the center of hub, so that's cool. But from 35-45mph and then 60-65mph I am getting vibrations. Nothing violent, but definetly feel it and hear it.

My question is, could this be due to the fact at all that the rear is lifted and the front is not? Is it possible it will get better after I finish the front this coming weekend? Or is it possible it will get even worse.

Should I start thinking about a transfer case drop, leaf spring shims, new u-joints or even a SYE?

I hate only being able to work on this thing on Saturdays because now that leaves me 6 full days of obsessing over it. Lol

Thanks in advance guys for your replies.....

 

The u joints are prob making the noise, they like to make noise once you lift jeeps. And only have the back lifted will not cause any prob.

 

So should I replace u-joints before bothering with a transfer case drop or shims?

 

I would, they are cheap and easy to do. you should not have a prob with a 3 lift, i know you did end up with 4.5 but thats prob due to saggy leafs im guessing. I would due the u joints first then a t case drop if needed.

 

TC drop kit would be the cheapest and best bet since you are at only 3".
