I just changed the gear oil in both 95 Z28s. One is 3.23 and the other 2.73.
With both wheels off the ground and rotating one tire, I noticed that the
2.73 acted very much like a non-posi rear end. The other wheel rotated in the opposite direction and did not turn the drive shaft.Not being very informed on traction locking differentials, could someone clue me in on what I'm looking at and if the posi-traction has gone away, what would be the best replacement to restore it?
I've been looking at Summit Racing and see some lockers but don't know if that's what I want for regular street driving. I don't understand the difference between "open case" and limited slip. PowerTrax has a $310 unit which doesn't include the "carrier". I'm left wondering if I will need a carrier. The more I write, the more ignorant I'm sounding but that's where I'm at.
thanks
