Will it hurt the performance of the car and how can I fix it.

 

Get a 12 bolt

 

yeah, thats bad. Need a new posi unit.
Time to upgrade to 12 bolt or Moser 9 inch.

 

Well... it's not too bad. I mean it won't affect driving car around town or anything. But what happened is your auburn carrier has chewed itself up enough where it won't grab for posi. It's kind of hard to explain, but that kind of carrier bites into itself on either side and that is how it provides posi(along with the springs and other stuff). It sounds like your carrier has no more bite left. If I were you, I would buy an Eaton carrier cuz unlike the auburn carrier, the Eatons are rebuildable. But your performance loss will be bad. These cars don't even like to hook up with both tires turning, much less just one. It's not the end of the world though thank god.

 

How much will it cost to get it fixed, if I was to go get 12 bolt.

 

12 bolts are $2k up to $3,500. A take off limited slip from SLP is $99.

 

Unfortunately, they are expensive 1800 to 2500
If you are bucks down you might try to rebuild the stocker but they are notoriously weak. I have gotten mine to live with 3.73s and a TA rear end girdle but I run street tires all the time and as long as your spinnin your rear should be fine, if you run a full slick and get the car to hook you will grenade the rear in a relatively short time.

 

yeah you can get a zexel torsen diff from slp for 99$ you can somewhat strengthen the 10 bolt but if you buy full slicks one day you may as well invest in a 12 bolt or 9 inch

 

i am not planning of getting slicks, my car does not have big mods so it does not hava a lot of power and i have 2:73s at the back. I was thinking of getting 3:42s and stronger carrier, if i did that would that fix my posi problem

 

Go with 3.73's and an Eaton carrier.

 

you mean both wheels don't burn?

when my auburn wore out, it still locked up both wheels...all the time! no limited slip

the SLP take off is way better, which is what is in there now, w/ 3.73s

 

I tried doing a dounut and there was only one tire mark. Also my car is 93 z28 and 3:73s I think will be bit to much for me.

 

I would pull another straight line hole shot just to be sure. Maybe when doing the donut the inside tire picked up a bit and did'nt leave a mark.

 

Yep, when I had my 2.73's my 315 nitto's snapped my posi. I went with 3.73's and an SLP torsen(take off) differential. So far everything has held together fine.

 

I think my posi may be going also. Can somebody explain what the slp torsen(take off) is exactly. Or why it is so cheap? Also how do the gears work with it. You still gotta buy those right?
