After my outing at the track this past weekend, I have acquired a squeaking noise so to speak from the rearend, but only when I'm turning left or right. It almost sounds like the tires are rubbing something, but they're obvioulsy not. Here's the scenario, this past Saturday in the burnout box, someone noticed that my right rear tire was not spinning, and abut a split second after that, I heard a pop from that area, and then the car went sideways a lil bit. I went ahead and made my run anyway, like a moron, but everything seemed fine. I thought that maybe the posi had just gotten too hot, and that it would be ok after it cooled off. Later that night, after I had already left the track, I tried doing a burnout, just to make sure my posi was in fact still working, and it was, so I thought everything was ok. Well, so I thought, because last night, I started hearing this squeaking noise coming from the rearend when turning in either direction at low speeds. It almost sounds like I'm driving a car with a spool in it, you know, when you make a turn in a car with a spool, the inside tire is trying to turn as much as the outside tire, therefor making it squeal a lil bit. Could I have possibly locked up my posi unit? Any ideas or suggestions you guys have would be great, because I'm kinda at a loss right now on what it could be! <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

parking brake shoe rubbing the inside of the rear rotor. I had a new rear put in mine and they didn't tighten down nor center the shoe. mines loose and rubs the inside of the rotor as I drive. sometimes it'll do it if I'm driving straight, but always does it when I turn.

Just changed the fluid Monday, and it started making the noise Monday night. I used Royal Purple rear end fluid, but didn't use the additive, because according to Royal Purple, you don't need the additive. So tonight I'm gonna put the additive in, and see if that helps. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

I had a mysterious "squeek" for about 3 months till I took my car to school and put it on the rack and looked at my tranny tunnel and noticed the tranny overflow line(connected to the tranny then the torque arm) was rubbing against the tranny tunnel!!! I also has problems with the torque arm mount and it rubbed/punched a whole in my tranny tunnel!!!

Anyone else have any ideas?

Other than the parking brake shoe, it could be the clutch pack in your posi. Have you checked your fluid level?

I just read something on this. The rear end will squeak when turning corners if there is not enough or no limited slip additive in the diff. <img border="0" alt="[Chevrolet]" title="" src="graemlins/camaro.gif" />

You need the limited slip additive with any gear oil!!Im sure thats your problem!

Well, unfortunately, it's not my problem. I put the gear oil in yesterday morning, and the rear end is still squeaking. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

I've emailed back and forth with Torsen about the need for using limited-slip additive.
http://www.ls1info.com/article.php?sid=141
long story short, it is not required with the zexel-torsen differential because it's gear driven. There are no clutches. Not using the additive will give better performance, I guess better lockup between both axles. The downside is it will squeak but only in very tight turns. That is normal. Limited slip additive is used because quiet operation is more desirable than getting max performance out of the differential, and the difference in performance is also argued to be minimal anyways.

As for your squeak, I don't know what it sounds like so my response may be irrelevant. The squeak I had was a rotational squeak, and came from my driver's side wheel best I could tell. I knew it wasn't coming from the differential. It would happen always when I turned right, going anywhere from 5-40 mph. It would also sometimes happen when going straight. I could also tell it was caused by something rotating, and I eventually tracked it to the wheel and parking brake shoe. Coming to that conclusion (for you) would be fairly easy. All you'd have to do is remove the wheel and brake caliper, pull the rotor off, and see if you can shift the parking brake shoe by hand left to right on the backing plate. When I did that to mine, and it was fairly easy to do, it squeaked as I did it and sounded the same as the squeak I heard when driving. What happened is the retainer clip to the shoe that pinched it to the backing plate at the top wasn't tight enough. It's only a pinch clip. When I set the parking brake the shoe would shift to the side. Although it still operated properly, when I release the parking brake the shoe would stay shifted and as I drove one side would contact the rotor. It would shift the other way and squeak as it moved against the backing plate. Another simple thing you can do is dab some oil between the shoe and the backing plate, so if the shoe moves as you drive it doesn't squeak. That'll pinpoint the source of the squeak if it ceases after you do that. Hopefully that's your problem, cause it's a simple fix with nothing to replace.
