Finished lift kit, now have drive shaft vibration
 

First I put the lift kit (4" superlift kit) on the front end of my 83 CJ7
and drove it till the next weekend when I put the rear half on. Everything
was fine with only the front on. Now, with the rear on I get a vibration
from the drive shaft it seems at around 40 and up. The when I let off the
gas I hear a noise like a 10 speed bike would make when you are coasting
only heavier, click click click click.... etc.

The kit came with a transfer case drop kit but I didn't install it. Others
I have talked to said they didn't use the transfer case drop kit.

Has anyone else had this problem or can anyone give a comment or help?

Thanks,

I had exactly the same problem. Only I didnot know where to put them 6 large
shims I got left.....
After I dropped the transfer case with those Shims, the problem was gone.

There is another solution to that problem, the Slip Yoke Eliminator Kit. It
helps to give you ground clearence, but it will cost you an arm and a leg.

Re: Finished lift kit, now have drive shaft vibration
 

Install the T-case drop kit. All vehicles are a little diiferent from each
other. The install should stop the vibration. Or, at least minimize it.
If vibration still exists, you can tune the rear axle shims to completely
eliminate the vibration.

The clicking you hear is the sound of your driveshaft ujoints. They have worn
in at a particular angle and are now running at a greater angle. Be sure they
are freshly lubed. The clicking may go away as the joints wear at the new
angle, however they are likely to fail at the most inopportune moment. If I
were you, I would replace them.

The vibrations at 40 mph are caused by the now incorrect driveline angle.
Install the transfer case drop.
