Ok so I posted awhile back ago saying that I thought my Posi was going out. Well I think it is. Yesturday at the track I would be doing a burnout and only my right tire was spinning. Then when leaving the line I would hook with both tires then my right tire would start spinning really bad.

I have heard that you CANNOT rebuild the stock posi units. But yet a few of my friends who have done lots of work on F body's say that you can rebuild them.

I am about ready to put some 3.90's in the car and was going to rebuild the Posi if I can. If not, I am really considering just selling the 3.90's and putting the money into suspension parts then when the stock rear does go, to just get a 12 bolt instead of wasting my time and money on the 10 bolt. What do you guys think would be the best route for me to take?

 

i think it depends on which posi you have.

they put different ones in certain optioned cars i think.

research what you have

 

With an m6 I'd say buy a real rearend, instead of sinking money into a lost cause.
