Hello...

Firstly, awesome forum, I've already learned a lot from reading the posts here...

Anyway... my problems, and yes.. I know I'm being stupid but... I'm trying to lift the rear of my XJ just a couple of inches using lift blocks. Has anyone else used these to get a 2" lift? The stabilizer bar bushings comes really close to the tyre, about 1/8th of an inch.. maybe a touch more. Is that a problem for highway driving or is it OK?

The other thing is a mild vibration at 40ish mph and an occasional knocking sound. From reading other posts it seems like it's either the TC or UJs? Should I shim the axle and change the UJs or drop the TC first? Any help would be awesome.

In case you care it's an 01 sport with about 110k on the clock.

Thanks,
T

Stock XJ springs are pretty thin and flimsy, they are prone to get spring wrap. When a lift block is used with the oem springs it only helps the spring wrap to show up quicker! Stay away from the blocks unless you have swapped in some beefier springs. I would either get some lift shackles and an add-a-leaf, or just throw in a couple S10 leafs. I just lifted the rear of my 99 XJ by mixing in a couple leafs from an S10 Blazer with the XJ leafs. The rear was sagging at 16 1/2" from center of hub to flare, now it sits at 20".

If you could take a pic of the swaybar and tire, it would be better. I'm not sure exactly where you are talking about.

For the mild vibration at 40ish ,I would look at the tires. What condition are they in?

The knocking sound could be many things. U-joints would be good to look at, also check out the u-joints in the steering knuckles (wheel joints).

If you aren't lifted yet, I wouldn't worry about a t-case drop or shims until the lift is in!

Welcome to the forum!!!

Thanks for the reply... I read my first post and realized that I didn't explain myself very well...

Without the lift kit, the car is sweet, no vibrations, no knocking, nothing... just the sweet sound of purring Jeep.

With the lift block in, I get the knock and vibration...

with regards to the new leaf... is that just a stock leaf from some place like advance autoparts?

Thanks,
T

IMO any oem XJ leafs, new or not, should not be used with a lift block. You'll need a thicker, heavy duty pack to avoid spring wrap.

If you do a search, you'll find plenty of threads explaining why not to use blocks...so I won't go into that.


As far as the knock and vibration with a 2" lift, I would go after the u-joint first. Without going into a deep discussion on the geometry, lifting causes the u-joint to operate at a different angle. If the u-joint is older, it will show it's age by making noise or causing a vibration.
