so I recently upgraded my lift from a 3” rc to a 3.5” re. I installed a tc drop as a temporary solution. My new found issue is that with all of this installed it has the vibration issue under load as in only when the gas is applied. It’s not horrible. And it’s only at certain speeds. But it does it. My issue is it seems to be in the front? It noticeably is coming from the front of the Jeep and not the rear. So that leads me to believe a sye wouldn’t help my issue. Am I wrong? If I’m right what else could it be? If you’re driving down the high way and turn your head to the right and listen you can clearly tell it’s in the front not the back.

Will definitely have to do that. If it stops what could it be? Bad u joint?

Or possibly messed up pinion angle? How do you correct that? Adjustable control arms? I know in the rear you can shim the leafs but obviously that’s not the case with the front. Not sure if it matters but my current front caster measurement is 6.4 on the passenger front and 5.9 on the driver.

yes full rubicon express kit with their fixed length control arms
