Started out installing a set of rock krawler 2.5" springs and front track bar relocation bracket on my 2 dr Jk. So I decided to do an experiment. I only unhooked the shocks and sway bars. I did not loosen the control arms during the install. After I finished installing the springs and bracket I tightened everything up while the jeep was still on the jack stands. I know your not supposed to do this but it's part of the test. After putting the tires back on I took it for a drive and encountered death wobble and a lot of other shaking. The when I got back to the house I loosened everything up with the jeep sitting on the tires and shook the jeep a lot. Then I tightened every thing back up ( control arms, track bars, shocks, and sway bars). Then went for a drive. All of the wobbles and vibrations were gone!! I hope this helps someone. I've read a lot of threads about different issues people were having after a lift install so I tried this.

 

Good to know. Thanks.

 

Yeah good to know, thanks for taking the time.

 

No problem. It only added about an hour of work total but worth it. I was shocked at the results. This could probably help some of the people who are complaining about the quality of ride after a lift install.

 

Hello. I’m running into some really strange handling issues. No death wobble though. When you did this did ou loosen the bolts on both ends of all of the control arms?

 

10 year old thread Winesap. If you have problems arising it sounds like something is wearing out.

 

All those control arm bolts should be torqued down while the jeep is sitting under it's own weight. If you didn't do that when installing, just loosen all those bolts and torque them back down. I think the issue is related to your lean (per your other thread) which isn't right.

 

This morning I crawled under the Jeep and loosened all of the control arm bolts. I also loosened the track bar bolts. Then I rocked the Jeep as violently as I could while everything was loose. I tightened everything back up and took it for a short drive. Then I measured the height of each rear fender at the centerline of the axle. With a full load of fuel the passenger side was about 1/2 inch lower than the drivers side. It’s highway manners are better but still not what I want.
