Hi. I'm a new jk owner. I bought a 2011 2 door, in July it has 35,600 miles on it. I just installed a 2.5 rc spring spacer lift with rc 2.2 shocks. I also installed a 1.25 rc body lift. I have 35 inch general grabber at2 on order. Should be here tomorrow. Since installing the lift I have a vibration at 40-50 mph. So I purchased aev geometry correction front control arm brackets hoping that would fix it. It got better but still vibrations are there. I also got a alignment done. Can anyone help with this. Can't stand the vibration. Thanks.

 

If it wasn't doing it before, but is now, and you didn't change the tires, something has to be loose. Or check your front drive shaft boots up by the t case.

Sounds the vibration has something to do with the lifting. Couple of things to check such as tire balancing, angle of the drive train or lowering the tcase with some washers and new bolt.
