I bought my 2005 TJ after it had been fitted with a Rough Country 97-06 Jeep TJ 3 1/4" progressive coil/spacer kit, 92PERF1641. It is extremely sensitive to any bump in the road. I need some good advice from someone who can help identify the cause and possible mods that will make it more drive able. I live in the Seattle area but haven't been able to find a shop that can help. If anyone knows of a place, I would appreciate your help. Thanks.
Can’t help with the shop but pictures of the suspension and steering go along way in the forum helping you get the root of the problem and work towards a solution. The more pictures the better.
And I’d stay away from a lot of big chain shops. Ideally I’d say do the work yourself if you’re able as you’ll learn a lot in the process.
Years ago I had 4wp install new ring and pinion gears and a truetrac in my front diff. Shortly after that I had a loud pop on a obstacle, no breakages and drove fine from what I could tell. Fast forward to 2 months ago when I decided to tackle and axle build and swap my trutrac over to my new axle, I found there was no preload on the carrier and that one of the races on the carrier bearings had completely snapped and likely was that loud pop I heard years ago. I got lucky as that could’ve been a big issue.
Not suspension related but goes to show the lack of caring and low work quality they provide.
