Case Drop Made Easy
a suspension lift, the
driveline is moved down further away from the transfer case thereby
altering the drive shaft angle. As many of you know this causes all
sorts of side effects. Anything from rattling a little bit, to
downright knockin your teeth out. I had a similar problem with my XJ's
lift. On the deceleration my drive shaft would vibrate to
the point that people were looking at me wondering "What's that?"
Although this write-up is about my XJ, it applies to other Jeeps
including YJ's and TJ's.
To fix it I
first tried axle
shims....made it worse!
Then I called the ever-reliable Bob Supplee Supergod and he sent me a
Tera-Flex T-case drop kit. There was much rejoicing.........
There really wasn't much to the kit. Here is one side of it...
It's just some
spacers and a
few bolts with lock washers...
The first thing I did
was place the jack right under the center of the
transfer case crossmember.
Next, take the
stock bolts out.
On some models, you may have to keep
them, some you don't, and some are studded (which is a pain in the
Mine were studded so I
had to once again weld the nut to the stud and
back 'er out slow......
Lower the jack about 1-1.5" down just enough to get the big silver
spacers in there.
try your best to line it all
back up and set the four bolts first
before tightening it all the way up. Remember, if you let the jack
you've got the weight of the entire tranny, t-case and the back half of
the engine. Don't force something that doesn't want to go and make sure
your bolt marks are sort of where the factory bolts were. You can tell
by the scratching they leave.
