I hate to beat a dead horse, BUT..
'95 Cherokee, 200K miles, 2wd, NO lift kit, tires balanced and
rebalanced, front end supposedly aligned, tried a different set of
tires courtesy of a front end/tire shop... entire vehicle vibrates
after hitting road bump at highway speed. Slow to 20 mph or so and
goes away. I've seen a bazillion answers for this.

Thanks

Steering stablisiser / damper not working properly ?

Also o see how much play you have in your control arm bushings, steering
bushings etc.

That is called the 'death wobble' and is caused by a marginally or
really worn part overpowering the steering stabilizer shock.

Check out the stabilizer for signs it has leaked.

If the stabilizer is still good, then some other part is seriously
dead. On a 95 I would be suspecting the stabilizer first though.

That shock is on the steering to keep it mellow when parts wear
slightly. A 'perfect' front end usually doesn't need one, but parts
wear, so 'perfect' doesn't last long.

Thanks, the most common answer I'm seeing is steering stabilizer.
I've also seen ABS kicking in, U-Joint, re-re-re balance, drive shaft
is not aligned right, etc, etc.... after running a Google search, I
was amazed at how many folks out there are spending THOUSANDS to find
the problem only to have it back at the shop to tell em..try again.
I've called every Jeep dealer in the Dallas/Fort Worth area and none
claim to have ever heard of the Jeep Death Wobble. I don't believe it
for a second.

Question, stabilizer is a cause, or a result of something else gone
wacko and putting too much strain on the stablizer?

I venture result, but of what, dunno. :(

Found that having uneven tires on the front (tread depth difference
of about 1/8") contributed to my problems. Putting the closest matching
tires up front eliminated my last run-in with DW before getting new tires.

Balance will also start the problem.

Once wobble sets in your tires are going to get cupped badly. I've found
that stiff shocks stop the problem. Perhaps my choice of Edelbrock IAS
over RS9000 was not good. Next year the IAS shocks are coming out and
I'm putting in the RS9000 adjustable. (and a compressor)

Jeep has to know about this but simply will not admit it till enough
people die as to affect sales. :/

Last time I had DW, I took the local Jeep head mechanic and manager on
a short highway drive. They almost climbed out the window when wobble
set in on a highway curve at 50MPH. :) But I did get new shocks,
stabilizer, tire balance, and suspension checked. Problem did go away
for a while but comes back every so often. (like last month)

Wish someone has "the answer".f

If everything is perfect. no wobble.

If the stabilizer is worn and/or parts are worn, you can get the DW.

The stabilizer can be the cause on a vehicle with 200K easily. No old
steering system is 'perfect', so the stabilizer needs to work. That is
what it is there for.

Cars don't have it, Jeeps and other trucks need it.
