These cars DO NOT like to be lowered.

I hate to sound like a "doubting Thomas" -- even though my name is Tom.
But, the symptoms you describe tell me you probably have damage you are not aware of.
My '92 doesn't behave that way.

Let's focus on the "glue" for a second. I have not had a chance to get under the car since my first post (track day at Putnam Park on my bike and TONS of rain) but I am will to bet the guy that put my clutch in DID NOT reglue this joint and I am getting the dance as a result. The next thing I will check is the inner tie rod ends. I can get in the pit at one of my shops and shake the car left & right and up & down and be able to see the suspension with all the weight on it.
Mackeyred96: I did not raise it back up and probably won't if I can avoid it. Check out my other posts about this thing being lowered.
Thanks for the help guys.

Please post the answer to this, I'm very curious what the outcome is.
Just using logic my guesses are:
1) Rear tie-rod.
2) two aluminum control arms or rubber bushings from the bearing housing forward to the frame.
3) C-clip broken off in rear end that holds side yokes from coming out.
4) Rubber bushings that hold batwing in place.

Check also the big 36 mm nut at the center of the wheel. If it is not torqued (to hold the splindle) the car act as you described.
I had the same problem and I found that this 36 mm was not torqued down enought. (I was able to loosen it by hands
).

When I had my C-beam off for a clutch change I didn't bother with the sealant. My car never sees rain or snow so I think I'm safe. No problems at all.

If you have a few days to fix it, order those clamps. To be honest, I don't know if they helped or not because I had to replace the trans soon after I got the car and they've been on ever since.
My sole reason to get them is because I have realitively large hands and it was a major pain to get the bolts out. There isn't much room up there and it makes removal and installation of the C-beam an easier process when the time comes.
Something to think about.

C-beam was tight. Jacked the car up again. I shook the wheels by hand...not much play. Stuck a 2x4 in the spokes of the A-molds for leverage and the left one moved about 1/2" up and down. I am willing to bet that is the problem. I will let you guys know.
A while ago somebody posted a thread about $55 rear wheel bearing hubs. Anybody remember this?

Well, the new bearings are in (all 4) and the dance is over. I found a BAD u-joint while I was in there. I just had those replaced last year. I still have some play in the bearing but nothing like I had. But now my check ASR/ABS lights are on. I checked connections. Any more clues?

Most likely a ABS wheel sensor on the rear wheels.
Are they plugged in correctly?
No broken wiring harness to the sensors?

They seem to be plugged in fine and wires look good. I pulled the ABS Hydraulics fuse as the ABS pump would start running as soon I got rolling. I am going to have somebody read the codes for the ABS/ASR computer next week when I get back.

I'm glad to hear you identified the problem.
I'm puzzled why it took the leverage of a 2x4 and
the earlier attempts by hand didn't reveal the bad
bearing. IIRC, you are a big guy and probably
weren't being dainty in the initial attempts.
Now that you've had it apart, any observations or
suggestions for others to consider while they are
trouble-shooting?

I shook the wheel a bunch of times and found the bearing to be loose, but not enough to make me worry. Then when I stuck the 2x4 in there, I had tons more leverage and saw how bad it really was. The car only squatted under accel or decel pressure, that puts more pressure on it than just pushing the car up and down and side to side.

I was wondering whose wheel bearings/hubs you used when you replaced all 4 and what you had to pay for them. I ended up paying almost $400.00 for a new RR.
Glad to hear that you got the dance corrected.
