I'd start by checking the U-joints in the front drive line, and the tranny
mount. On the earlier CJs, if the tranny mount parted it allowed the
cases to slide far enough to the right that the front drive shaft yoke
would whack the floor pan.

So that's why they moved the front drive shaft to the driver's side. ;^)

Your t-case is a 'shift on the fly' one for 4 high. You can shift into
and out of 4 high at any legal speed. I treat it just like any other
shift in my Jeeps. When I see a snowy patch coming on the highway, I
shift, then when I see clear again I shift back to 2 wheel drive. I
also find 4x4 is nasty when turning left at a slushy intersection
because one front wheel has to scuff so it gets up on top and wants to
go straight so I shift to 2 wheel drive for that, then back to 4x4 as I
come out of the turn.

Your 4 low can only be shifted when either stopped or rolling along at 2
mph or so. Most like to be moving slowly for the best shift, but they
pretty much always clunk a bit.

The knocking in 4x4 is not a good thing. I would be checking the 5
front u-joints out for a bad one. The driveshaft has 3 and there are
one at each axle end.

If you have a bad engine mount, the engine can slide over and the front
Yoke can hit the exhaust making a good knock or grind. The driver's
side one seems to go first.

Your front axle locks via a vacuum motor when you shift to 4x4. If this
is leaky, it might not allow a front lock which can be noisy.

The speedo cable goes into the back side of the t-case.
