ok, i did a lot of burnouts with my stock rear, and now it like clicks when i try to take off fast...i think i knocked some teeth off or something, do i need a new rear or could i buy like new gear stuff and a posi kit or something like that and rebuild it?

 

you could buy the stuff to fix it. what rear do you have and what's in it?

 

i'm not sure...its the stock stuff in a 1985 trans am 5.0 liter H.O.

 

You snapped the carrier most likely...

And the spider gears are finished..

Damn 7.5" rears..

 

your likely going to need a new carrier at the least. it's a shame you aren't closer, i have a 28 spline 3rd gen rear for sale with 3.23 gear. if you pull the cover and only find the carrier broken, i'd just order the slp take out torsen and a set of axles. they will suffice under decent power and be a cheaper way out.

 

oh, just a thought came about, you may want to look at the differential cover to find whether it's a borg warner or ten bolt gm. you can also find out by listing the rpo' you find on your list under the letter g such as g80, etc. i believe that will be a 9 bolt after thinking about it, but not really sure without some more info.

 

My rear end has been dead lately, too. Not even the bran muffins are helping
