View Full Version : Leveling Jeep with Coilover Preload

11-11-2019, 05:21 PM
After a wheeling trip six months ago I had a really bad passenger side lean, primarily up front. It was about 1.25" lower on the passenger side and after a thorough inspection nothing is broken or loose. I have since adjusted my preload in the front to level the Jeep, 1-1/8" driver side & 2" passenger side.

Does the difference between the two seem excessive? Is it possible that I have a bad spring on the passenger side? Is there a way to test that?

Here is what I have for preload:

FD: 0.727 FP: 1.362
RD: 1.784 RP: 2.42

Easiest way to test for a messed up spring is to swap sides and see if the lean follows.

Another note...

I had an issue with lean when I first built my Jeep.

It ended up being the rear upper control arms causing the suspension to be in a bind.

I removed one of the upper rear control arms and leveled everything out. Once it was sitting good I changed the length of the removed control arm to line up with the bolt hole. Everything has been great since then. It was only off by like 3/8" but that was enough to cause a 2" lean!
