Re: TJ having a worsening "shimmy" problem
You may need to replace your steering box, tie rod ends, ball
joints, wheel bearings, and Universal Joints, and out of align, but it
can't shimmy without a weak steering dampener. You may need two cover up
your modifications:

With a TJ, you can go into 4Hi at highway speed even on the
highway. The owner's manual says as much. A shift into 4Lo requires a
speed of less than 3MPH.
If his rear diff is a limited-slip, that would account for the
reduction in "shimmy" since the LSD tends to resist a change in
direction favoring a a straight line instead.

Sure you can 'shift on the fly into 4 high' on almost any Jeep on the
road these days including my 86 CJ7, the problem is the wheels 'must'
scuff the ground in order to not explode parts on the TJ's 'Part Time'
4x4 system if you vary from dead straight ahead.
Driveshafts turn into pretzels doing that if you are only lucky. If you
are 'very very' lucky you only explode a u-joint, not take out the yokes
too, my old roommate blew his t-case in half, literally, doing that....
Too much traction!!!
You only are supposed to go into 'Part Time' 4x4 when the roads are
slippery. Dirt or snow works fine, dry pavement doesn't...

Sure you can 'shift on the fly into 4 high' on almost any Jeep on the
road these days including my 86 CJ7, the problem is the wheels 'must'
scuff the ground in order to not explode parts on the TJ's 'Part Time'
4x4 system if you vary from dead straight ahead.
Driveshafts turn into pretzels doing that if you are only lucky. If you
are 'very very' lucky you only explode a u-joint, not take out the yokes
too, my old roommate blew his t-case in half, literally, doing that....
Too much traction!!!
You only are supposed to go into 'Part Time' 4x4 when the roads are
slippery. Dirt or snow works fine, dry pavement doesn't...
