So far, I'm still pulling 2 wheel burnouts in a straight line, but it's only a matter of time. I'm looking for junkyards.

i have the same problem with mine, and i have 34k on my hawk. same exact problem with the one-leggers and the noises. I put it away for the winter before i could really do anything with it. THe first place its going is the dealer when i take it out again...do any of you guys know if the dealer would cover it. I have a GMPP extended warranty.
thanks, john

I was under the impression that the Zexel doesn't have clutch packs, just the Aburn diffs. I was also under the impression that the 99+ cars had the Zexel. Here's what I've seen:
"In 99 The old disc-type limited slip differential (Auburn) was replaced with a Zexel-Torsen torque sensing limited slip differential. The new differential requires the use of synthetic differential fluid because of its design. The slip-limiting uses metal-to-metal contact inside the case and thus requires the use of the more "slippery" synthetic lubricant."
So anywho....back to the rest, I won't change the gear ratios, I've got an automatic so anything beyond my 3.42s is gonna hurt me more on the highway than I'd like. I just changed my fluid too, after it started acting up; metal was clean, minimal shavings on the magnet, fluid was clean, everything seemed to work good.
Yeah, the clunk noises only happen during the turns. I just don't know what inside it has died. That's really what I want to know.

When a posi needs a fluid change or is starting to go bad it will make a popping noise during turns, but only a auburn or eaton. If it is popping in turns you can try adding some friction modifier, then do some figure 8's in a parkingf lot. That will help work in the additive into both sides of the posi. The torsen shouldnt make a noise like that at all unless it needs replacement since it doesnt have clutches or cones in it.
So, is there any way to rebuild it? And where can I find a good stock replacement? I don't want anything spectacular, since obviously I'm not gonna be pumping a whole lot of power through it. Just a set of 3.42s with traction control and ABS? What's the best route to go? Whole rear end from a junk yard or what?

Hey man let me know if you guys get any answers to the ?'s
You all are askin. Cause my best friends SS rear end is acting up
bad. But I think we have to put new gears in it. Hell our hardest part
is finding some one in the area thats any good with rear ends.

Verdad Gallardo Well, I assume it's the cones. Anyways, what are cones? I wont be upgrading mine, so a repair, or a stock replacement is in order. I don't have a ton of money to throw around, maybe 100-200 bucks tops. Can you explain the cones to me a little. Finding information on rear ends is near impossible, it's like its all secret and nobody wants to let you in on it.

Mzoomora, I appreciate all the knowledge you're sharing. Thanks. What should I look for to be broke? Everything looked good with the cover off, but that's not real in depth. One more thing, if I just replaced the differential itself (the carrier) and don't remove the pinion, will the gears still mesh correctly? Will I need to check the backlash and pinion depth? I guess what I'm trying to ask is, if I just swap out the carrier, will I have any issues?
You cant really see too well into the Torsen cases. If you replace the case all you need to do is set the backlash and preload the bearings. Take a measurement of the backlash before you remove it, and just set it the same way with the new case. You will need a magnetic base a dial indicator.

"We all do dumb things...." said the Geiko commercial. I changed my fluid in the diff and replaced the fluid with 80/90 oil w/one bottle of GM posi additive. I was reading my owners manual today and it said I was supposed to use synthetic 
Would this cause my posi unit to not function properly or at all?
Would this cause my posi unit to not function properly or at all? Still no news on what caused the unit to die? No news here either? I found a new Zexel Torsen Differential online. They say it's an SLP unit, but it looks like a good deal. $120 bucks and it's new. I'm prolly gonna order it soon.
Hey guys,
I'm glad I found this thread. I have an 02 Z with 10k miles on it and have the same problem i.e right wheel spins only when turning right. One of my friend owns a Firehawk and I told him my situation and he told me its cause of my differential and that its normal. My other friend has an 98 Z and he does not have the problem. So being that I still have warranty I dropped it off today at the dealer. Stay tuned for what they diagnosed.
