hello people i am one of the new dudes i have an 85 iroc that i just put back on the road after 8 years . When i had it on the road last time i drove around whith to diferant size tires on and now I only have one wheel peal what should i look for when i take the rearend apart. Tanks for any help I know now how dumb that was.

 

If you know for sure it has a posi unit inside, you may get by with a fluid change and new bottle of posi additive. Cheap, easy, and probably not a bad idea if the car has some miles on it.

 

Yes it was a posi rear and i did not drive to many miles Whith the two size tries on it mybe a 4500.I hope its as easy a you suggested . Thank you for your reply i like this web site .
