Determining health of transfer case, pinion, transmission
 

Since I've had this jeep I've had like a "shimy" or sometimes even a violent
vibration when letting out the clutch in either first or reverse. It's
actually the worse in Reverse. I can sometimes rev the engine higher and
get through it easier but it still happens to some extent. I've had a new
clutch put in and corrected the linkage but still have this vibration.

How can I diagnois the cause of this shaking?

I guess one thing I could do is remove the rear drive shaft and see how it
responds using the front drive shaft.

Thanks for any ideas.

Bill

Clutch chatter I believe.
My old 88YJ used to do that.
Apparently I should've turned the
flywheel when I replaced the clutch.

my old YJ had the same problem, as well as another manual tranny-equipped
car I had. Both cases, it turned out that the flywheel needed resurfacing,
which should have been done during a clutch replacement job, but was not.

Re: Determining health of transfer case, pinion, transmission
 

That is a symptom of a broken motor mount. Having said that, I thought you
have recently installed new mounts. There is a third mount, in addition to
the two motor mounts, that supports the trans., it is located under the
trans and is bolted to the skid plate. This one is often over looked, and
can cause the symptoms you report.
