So here's a question... I bought a 9 bolt with PBR's and installed it on my Bird before I left Cali. I liked this choice for the rear disks (better stopping) and the compromise between staying at 2.73 and going to 3.42. The 3.27 was a nice improvement from the 2.73 peg leg.

The question is how do I know if the posi is worn out or not? If I step on it from a stand-still the crappy TBI won't break traction (and it hooks pretty good actually) but from a corner when I accelerate I only get one wheel spinning -- usually on the inside wheel of the turn.

Is the posi supposed to work that way?

pretty much yea. if it didnt allow one wheel to free wheel during turning you are more likely to spin the car. the 9 bolt is a limited slip diff not a locker

is the rear end for sale how many miles on it? was it working when you pulled it?

sounds like its shoot, or on its way out to me. with a positive traction(limited slip, same thing) rear it should basically act like an open diff until maximum traction is needed then both wheels lock together basically. In my cars if I hit it in a corner it will either hook and go, or spin both wheels and the rear ends comes around. You could also do a burnout and see if it leaves 1 or 2 black lines

we might be thinking of 2 different types of corners. if you are exiting a corner from a stop say like turing right from a stop sign it will burn up only one tire , but if i throw it into a corner at speed the rear end should be locked.

sounds like yours is shoot too. I never had a car with posi spin just 1 wheel

well i could be wrong, it always hooked up on the launch and thats where i need it anyways.
