One problem I've been having with the jeep is coilover noise. Anytime they move, all you hear is this annoying squawking from the springs rubbing the shock bodies. The first trail day in Moab was a bit embarrassing (for me) with my jeep creeping around with all that racket. Day 2, we put some zip-ties around the parts of the springs that were touching to provide a plastic barrier from the contact and that worked pretty good for the rest of the trip except I had to reposition them a few times. I had heard somewhere (here maybe?) that KING redesigned the 2.0 sliders, and since my shocks were built several years ago, I figured I had the old design. The sliders were not holding the top and bottom springs straight at all.
I found the KING booth at the vendor show and even though the guy told me the new sliders would not fix my problem, I bought 4 new ones anyway. I don't trust any salesmen over my gut feelings
Last night I broke the shocks down while having the tires off and swapped out to the new sliders. I didn't get any comparison pictures between old and new, but after some measuring with calipers, I knew these new ones would be way better.
The ID of the new style is quite a bit tighter than old, plus the bottom portion much longer.
Once I got it back one the ground, wallah! none of the springs are touching anywhere.
So if you are having this same problem, spend 60 bucks and get the new ones.
