I did a burnout today and only one wheel spun?? Whats up with that? I recently changed the diff fluid and added that posi liquid. But not the gm one. Anyone have an idea what might be wrong??

 

Is it the stock Posi? They tend to wear out fast under hard abuse. They dont take long. I have went through 3. Finally steppin up to a 9 inch with a detroit locker.

 

yea its the stocker. How much is the other one?

 

Well the alternative to replace the stocker is an auburn carrier for a stock 7.5 rear. I have this in one of my Trans am's and it never lays only one tire down. It is costly though. I think I spent 600 for it with installation. I also had the gear changed when I was in the rear.

 

well that might be a good idea! I just get the posi and do the 3.73 gears while im down there right?

 

GM told me that my car has unequal back pressure could that be the problem?

 

anyone else?

 

my best friends camaro did the same thing... we opened the posi unit and found this:

wow whats that?

 

That would be his pin gear shearing off the retaining bolt and walking around in the housing. Not a good thing.

 

Bingooo.... the oil was so shiney... we got a magenet and glops of oil metal stuck to it when we dipped it in, thats what happens when your rear dies on you.. heh

 

Eaton is another good LSD. Mine is the only thing I haven't broken in the 10 bolt besides the axles and one of them has wierd wear marks where the bearing and seal ride. Wanna buy a 2yr old Eaton? My ride's down right now waiting for funds to get a 9" or 12 bolt.

 

would anything happen if I kept on driving it like that?

 

my friend drove like that for almost 1/2 year, but he knew something was up when he went through 3 rotors due to scraping on the caliper mount, when we pulled the wheel, the axel came out by just PULLING on it... so.. it had the potential to be REALLY bad, instead of just bad...

 

How are the Zexel Torsion Posi units as a replacement?
