Ok, I've had this popping noise coming from the back of my 1999 Jeep Wrangler for some time now. It doesn't do it all the time, just as the Jeep warms up and is driven for a while it starts, especially when driving slow.
I have replaced the rear brakes and calipers, shock absorbers and today (yes, all day) replaced the ujoints in the back. Still the popping! Could it be the rear wheel bearings.
So, I thought I may post before replacing every part on the dang thing and see if anyone else has had any experience with this problem.
