So I drive my jeep everyday with 4.5 in lift tc drop and saving for sye. I am currently experiencing vibes coming from under my driver floorboard at 25mph and up. They only go away when I slow down below 25. I also just replaced the driver front wheel bearing. This seemed to improve slightly but still not enough. I have tried adjusting the control arms and am getting it realigned tomorrow. Anything else I should have them check?

If you have any other questions about my set up or thoughts please help. 6 pack to the first person who comes with a solution that works lol!

Check the trac bar. One end is bolted to the frame on the drivers side, the other is bolted to the axle housing. The end by the frame has a ball and socket type joint similar to a tie rod end. The end on the axle housing has a bushing with a bolt going through it. If either end is worn, it can cause quite a shake. If your rig is lifted 4.5", you should probably have a longer trac bar installed. There are adjustable trac bars on the market for that application.

 

Have a brand new adj track bar installed. So I don't think that is it as it doesn't look fairly worn yet. Just installed it about 4 months ago. I will double check it tomorrow though.

Thank you
