What is wrong when a posi rear is running "peg-leg"?

I have a Borg Warner RPO code GH3 (2.77 Posi).

 

clutches or springs worn out or broke. have you changed oil lately? you need gm posi additive with clutches

 

The posi is worn out. In the case of a 9 bolt, the clutch cones and inner housing is worn.

I am not allowed to post a link or give you information on this, so hopefully someone else will!

since i am try www.9bolt.com they have a lot of 9 bolt parts and great people and service

 

Kool - thanks alot guys.

I wont ask why you cant post the links.

 

rules aginst using TGO as a means of advertising, miles owns 9bolt.com so he can't post it or advertise it

 

when u sayin the inner housing is worn, is there a way to tell for sure and does that mean the carrier is no good? id like to here more info on this please.

 

Thanks ede!

The cones ride against the inside of the carrier halves. As the cones wear, they ride deeper into the carrier. Once they bottom out, then the posi stops working and the cones start chewing up the inside of the carrier halves. The only way to know for sure is to take it apart.

 

no problem miles, i'm not really such a bad guy, i just play one on www.thirdgen.org

 

alright so it should be visible, would this wearing of the carrier cause a "clunk" or somethin, i have two nine bolts that clunk going into gear.

 

If this is any interest, I saw a 9-bolt on a '85 T/A in the boneyard yesterday. No one had even messed with it yet. Tires were still on the rear-end. Still had the tag on the back. If it is still there tomorrow, I will pull the cover and take a look at the gears.

 

Both of mine clunk too - the one that is peg leg like will not spin both tires on dry pavement - it will clunk and spin them on wet pavement.

The other will clunk and spin both tires on wet pavemant AND dry pavement.

 

i wanna figure out what causes this

 

correct me if I'm wrong, but from what I've been told, most of the time, true posi rearends make a clunk. don't know why, they just do, prob something to do with the posi unit.

 

A posi unit should not clunk.

The clunking noise is coming from excessive back lash, or play in something. If the posi doesnt' work, the cone clutches are worn out/and/or the springs are weak. In my expirience, it's usually both. It's as simple as that.
