I'm new to this forum but have been posting in another forum about my Death wobble issues. I'm hoping maybe there is someone in or near the Sacramento area willing to help diagnose this thing.
Here is what has been done
New MOOG trackbar with 7/16" bolt upgrade.
New Durango Steering Box
New Drag link
New Tie Rod from ZJ
New Clevite upper and lower CA bushings all 8.
New Rancho RS5000 Steering Stab
Tires road force ballanced
Removed and inspected Unit bearings
Verified Balljoints are good
Verified u-joints in axles are good
Inspected all axle mounting points ect.
This is an 05 TJ sitting at stock height with stock size GSA tires. I've owned the jeep since new in 05. It has right at 60k miles.
I really need a second set of experianced eyes on this. I have taken it to 2 jeep only shops whom "inspected" and road tested the jeep. Basically as they say "you replaced every single part, so we have no idea why it is doing it."
But I'm second guessing my self. So if you can help me out I'd really appreciate it. It DW's at 55-65mph or so. Hit a bump, you know the normal DW issue for a Jeep.
There is a caveat to this though. I have perform a test by towing my jeep by it's tow bar. Of coarse it DW's at the speed it normally does. However, out of curiosity I pulled the pads off the calipers and it doesn't DW.
Has anyone heard of, or maybe witnessed a sticky caliper causing this issue? I have a slight pull to the right when on a brand new flat road. Also Yesterday on the freeway I normally drive, no DW on the first trip. Second trip DW. It has done this several times, I'm wondering if in fact it is a bad caliper.
I also noticed and asked in another forum but no one answered the following. My pads are about two years old. I was looking at them and the leading edge of the pad is more worn than the trailing edge of the pad. Meaning the pad is wedge shaped. I had a set of ceramic pads that I ran for a couple years still sitting on the shelf and I inspected them and they look the same way. Anyone seen wedge shaped pads when pulling them off thier TJ. I know that new they are perfectly flat.
