    I just purchased an 89 Sahara. Seller suggested I check the drive shaft angles after the lift kit was installed. The transfer box was left in the original position. There's a rear vibration when I accelerate. Can anyone point me to where I can find proper angles?

    You should really install a Slip Yoke Eliminator Kit (SYE) on your Tcase. I would run Advanced Adapter's. Pro-comp's and Rugged ridge's SYE and probably some others are made by Advanced Adapter and boxed under their label. This should eliminate any vibrations. The cheap and easy fix is to do a Tcase drop, but I don't like how that tilts the motor back causing the front pistons to run lean on both fuel and oil on carbed and TBI motors. You will also need to order a new drive shaft with the SYE.
