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...

Re: TJ having a worsening "shimmy" problem
 

Make sure that your lug nuts are tight. Look for missing wheel weights.
Have someone drive behind you and see if one wheel is wobbling worse than
others. Have you hit anything like a rock or curb that might have bent a
wheel? (I was dreadfully hard on wheels when I was younger) Try rotating
the tires and see if the problem changes.

Check the front hubs for play by jacking up each front wheel and attempting
to wiggle it by hand.
