I just recently purchased a 1987 Jeep wrangler that had a 3 inch Rough Country lift installed in it. I immediately noticed that the bushing at the rear of the transfer case was pushed through the seal and was on the spline of the drive shaft. I took the rear cone off the transfer case and replaced it with a new one with a new bushing and seal. I lowered the transfer case and reinstalled the driveshaft. I was hoping that the previous sharp angle of the driveshaft was causing the bushing to be pushed out. Unfortunately, lowering the transfer case did not help. Are there any suggestions?
