The rear sway bar is rubbing the upper control arm bracket. Its only on the right side. Why this is happening or hor to fix it.

Also the track bar is hitting the spring. Can be because of the same problem?











I have a 4 in rough country lift kit. Thanks for the help

Do you have adjustable control arms and track bar? Looks like you need to center your axle with an adjustable rear track bar and change your pinion angle with the control arms. Hope this helps.

I do have an adjustable upper control arm.

Your links are not vertical. This is due to not moving the rear swaybar back.. U want those links vertical. What I did is move the mounting brackets for the sway bar back. I put the front hole into the rear hole In the frame and then drilled and tapped a new rear hole. Also u might need to center the axle better using the track bar.
Also looks like u might need longer links also.. On level ground u want front and rear swaybars sitting at level or slightly up from level... Not down.. Yours look to be down.. I posted a pic.. Its hard to see but under the frame side of the track bar u see my link vertical.. I will post a better picture when I get home to my jk.
The trackbar hitting the spring issue I fixed by installing jks perches. U could also cut the stock ones off and re weld on to make the spring vertical.. This problem happens when u correct the rear pinion angle because of where the stock perches are welded on the axle. The wedges u have work ok, but the fix is like I said. Tf also makes stock style perches. The jks ones are big and don't work good with the tf rear tb bracket on the axle.

Remove the rear sway bar... More fun to drive

Definitely would not remove the rear swaybar especially on a 4dr. Makes for a loose scary highway ride... Here's a few more pics for u to show the rear bar angle and links angle.
BTW in regards to the removal of the rear swaybar... I did it and reinstalled it two days later due to the horrible road manners.

rinkishJK thanks a lot for all that great info and pics. I will take a look at everything you mention specially moving the brackets back. Hopefully that will fix it. When I get home I will measure the wheels to make sure that the axle is centered and worj from there. Ill keep updated just in case more help is needed.

No problem. post up your findings.

Hey rinkishjk you think you can put more pics of how you moved the sway bar bracket back. One question . Do you have the stock muffler? Because I try to do it o er the weekend but I saw the muffler too close to where the new location is going to be

I can post more pics when I get home later.. I have an mbrp exhaust and the swaybar did touch it.. What I did was loosen the exhaust where it goes over the axle, and slide the muffler rearward a bit to clear the swaybar, then tighten exhaust back up. That will move the pipe out of the exhaust a bit, but still has plenty to seal.
