So, my rear end finally blew up, but it did it in an interesting way. One of the bolts holding in my pinion gear backed out, loosening up my pinion gear, and that in turn, ground my pinion gear actually in to my posi unit. Well anyways, I need a new posi, I've already got some new gears, and I believe (according to the mechanic) a new spider gear and 3 new bearings? Now I don't know too much, so I have no clue what the spider gear and bearings are for, just trusting the mechanic(he's a good one) but, where would be the best place to get a new posi? I don't want a locker, because I like handling more than drag racing, but I still want a hi-po unit, so I was thinking an Auburn Hi performance unit, but I don't know where to get it. Also, is there anything else I should know? Please reply soon, I need my car back Thanks for your help.

 

SLP Zexel Torsen... $100

 

Or if you want to shell out a few more bucks, Eaton posi. Jegs and Summit both sell them.

 

12 bolt

 

Eaton and a rebuild kit will run around $1000 total... save some more and get a 12 bolt:P

 

Yeah, I've got a 12 bolt, but it was not easy to finance. Unless he has big plans for his car, he could probably get away with a good posi and rebuilt rear. 1000 dollars is far from 2500. If he was snapping ring gears like I was, and having 500 dollars worth of work done every six months, then it would be a different story, but i'm not one to advocate 2500 to a rear end that will never be needed. 2500 is two semesters of college not including books (at least where i go.)

 

Thanks for the replies, yes, the 12 bolt is too much, I won't need it, I don't drag my car too often. Well, eaton posi, I've heard from some people these aren't as good as auburns. Well, so, no 12 bolt, any other helpful words?

 

From what I understand, the Eatons are rebuildable while the Auburns are not. My stocker is in bad shape and I'm looking at saving for the 12-bolt but if I didn't have such big (stroked) plans for the motor, I'd have an Eaton in there already. Oh, yeah, the 12-bolt will have an Eaton in it.

A few years back I bought an Auburn Sure Grip for my '84 Chevy 4x4 that broke the locker. The truck didn't feel as sure-footed as it did with the locker -- ie: it acted like it had an open rear more often than I liked. Note: the Auburn Pro has a higher spring pressure for better 'posi' operation -- sorry, can't remember exact terms on their website. Last I checked it was more than the Eaton ($$$) and it still isn't rebuildable. The Eaton can have the clutches replaced if they get burnt up.

 

SLP Torsens are back ordered infinitely according to them. They are missing a pin, and can't get it to complete the differential.
