Maybe you tire **** is rubbing because you have a stock panhard bar and are lowered 8". It sounds like your geometry is all out of whack and your u joints are hammering themselves apart.

Lsd doesn't lock the wheels. That's why it is called a limited slip.

to me, it still sounds like worn bushings. you said yourself, it all worked good at the start of the season.

with the car on the ground, in first gear. lay on the ground near the rear wheel, and rock the car back and forth, look to see how much movement you're seeing with axle roll. you might be getting the wheel hop from the bushings loading up, and letting go as you lose, and gain traction. Like i said earlier, i went with heim joints in my toque rods to get rid of any of that wrap and i the axle doesn't load up at all anymore. i think between bad torque rod bushings or bad main axle bushings thats where you're getting your hop.

im not gonna dwell on whats proper and whats not, but a pan hard bar simply positions your axle laterally.. so i can't see it affecting vertical performance.

This is getting good. There has been plenty of advice in this thread from more then a few people who have done a various amount of little to huge suspension mods that have all worked.

When it comes to a welded diff you are now changing the rate that each tire spins. In a open diff or a locker the inside and outside tires will spin at different speeds when turning. That welded diff is great for going in straight lines but once you start turning that welded diff becomes not so happy.

So suck up your inflated balls and listen or you going to be figuring this out on your own and will probably never figure it out.

Now back to my pooooooopcooooooorn

I noticed ( and this may have no relation to your problem) On my car (93 945 t)with 235x35x19 REAR tires, that the tire pressure effected wheel hop really bad. I had a semi bald tire on the passenger side(new tire on drivers rear) on a 3 inch drop, when i put 40 psi in both tires everything was fine, 50 psi in semi bald tire on passenger side, mad wheel hop. Tires are rated at 55psi max. Like I said, just something to think about Since I did not read a mention of this. Cure was to replace tire or lower air pressure to 40/45 psi. Some times the fix is not so complicated.

Wheel hop on a non-leaf spring car is caused by the compression of the bushings with resulting sudden release of the energy?

On my old '79 Mustang, Lakewood made a traction bar for the Fox body. That was long ago, but it did the trick.

Not sure what it is worth, but this is my vote. you may need to get more aggressive with trying to rock the car, use your e brake as well as first.

dead bushings are guaranteed undampened play, don't waste your time on anything else until you know they are good.

I would bet if the panhard bushing is bad, then the lower axle bushings are toast (unless they were already replaced)

If you have not done them, now is a good time to do them.

Stiffer springs and shocks will exacerbate any issue with the bushings.

The following advice has already been given, but i will reiterate it.

When i first got into these cars, i put full poly in the back, which is a mistake unless you just want to drift and do burn outs, made my car worthless in snow and rain.
Stay with QUALITY rubber, or go with heim joints.
To me, poly was ok on the the panhard rod though, and seemed OK on the front trailing arm bushing, and front torque rod bushings, but 100% does not belong in the trailing arm/lower axles bushing imo.
+1 on tire pressure as well.

i have been a bit out of the game for a while but i think kaplan has heims for the lower axle to trailing arm bushing, someone else may too.

You could also fab your own for cheap if you have the skills. Get the parts from PolyPerformance or someplace similar.
