Limited Slip problem? '88 Supra LSD N/A

Supra. I noticed the other day that there was a new 'problem'. When going
from reverse to drive, there was an unnerving *CLUNK* when starting to
move forward. Note: I'm not one of those g00fs that leaves the car rolling
in reverse and then shifts to drive. The clunk happened a few times over a
couple days.

Then, when I was pulling out of a driveway where I could 'peg' it a
little, the rear tires were in some sand. I stepped on the gas, the car
started going and then there was almost a kind of chattering from the rear
end of the car.

Now, this car has Limited Slip, and it also has a competely Independant
Rear Suspension (IRS). So I think there's at least one fo two things going
on here:

Either the Limited Slip has developed a problem, or one of the CV joints
is going bad. I don't notice and clicking or clunking when driving the car
in everyday driving, but then again, with 700 Watts, who would?

Any ideas? Oh, two days before this started happening I picked up some
GL-5 (supposedly Hypo for *ALL* differentials "Including Limited Slip")
since I haven't checked the diff oil for two years. Also, I should check
the 'vent' while I'm under there, eh?

I'll spare you my standard "noises are difficult to diagnose without
experiencing them first hand" spiel <g>

If the sound sounds cushioned like the sound when a suspension bottoms out,
then make sure the bolts holding the diff to the undercarriage are good and
tight and the rubber bushings haven't gotten hard or developed free-play.

Take a look at the U-joints to make sure there isn't excessive play.

If the sound is very metallic, check diff backlash.
