This weekend I helped Jenny change the transmission mount on her XJ. While we had the cross member out we decided to remove the transfer case lowering blocks. This drop was put in to match the tapered lift blocks that came with her lift kit.
We removed the spacers and replaced the tapered blocks with flat blocks.
A test drive showed that the drive shaft vibes were back. I guess the drop is necessary for the 92. I have the same lift on my 88 with no transfer case drop and no drive line vibes.
We spent Sunday afternoon putting the transfer case spacers back in and replacing the flat blocks with the tapered blocks.
The drive line is now smooth again.
On of my passions is Jeep Cherokees. All my family drives XJs. Mine is a 91 four door with over 300,000 miles. My ex rally racer now turned off road Jeep is an 88 two door with a 4.7L stroker engine. Now with a three inch lift and 33 inch Maxxis Buckshot tires.
My older son drives an 88 XJ Wagoneer with a 4.7L Stroker motor. A real surprise at stoplights when this wood grain sided, white wall tired monster walks off and leaves muscle cars! His wife drives a 96 Cherokee Country.
My younger son has a 91 like mine except his is green.
My Wife drives a 99 Cherokee Classic. Our friend and business partner has a 92 XJ with a 3 inch lift and 31 inch Maxxis Buckshots.
