DW.. Death Wobble.
Something I'm not to unfamiliar with. :/ Try it at 85-90MPH.
Let me guess.. hitting a bump "just right" is at a diagonal.

It only gets worse.

You need to take care of this before the wobble scallops your front tires
or you dribble off the road. ^_^

Here is the list. (besides having too high a tire pressure)

1) tire balance/rotation/alignment (even a bad tire)
(a badly balanced tire/thrown wheel weight leads to DW)
If you have a bad tire move it to the back where it does less harm.
2) dead stabilizer/damper
(this shock, located on the drag link, helps reduce steering vibrations)
http://www.revbeergoggles.com/temp/front-suspension.jpg
3) dead shocks. If your shocks are original then they may be gone.
without good shocks the suspension in a ZJ is not stable.
4) Antisway bar mounts cracked or failed. This has the effect of not
damping both sides equally. http://revbeergoggles.com/swaybar/
5) Control arm bolts loose. Check the eight bolts (four on the body
four on the front axle). This takes a torque wrench to check since
even if they feel tight they may be loose enough.

At any rate, I'd have someone check the runout on your tires.

Yes. The axle end bushing is replaceable. If the ball joint end up at
the frame is bad, you have to replace the whole bar as far as I know.
That's how the rest (TJ, XJ) work anyway. Still not a difficult job.

If it's a wheel bearing, that's an easy fix too, you just replace the
hub on those. The ball joint is best left to a pro, it's an SOB to
change.

It's a wheel bearing.. just had the same thing with the wife's ZJ (also a
93)
