borg-warner 9 bolt question
I have the limited slip b/w 9 bolt. Seems like lately the passenger side tire is the only one spinning. I mean I can tell the limited slip isn't working. Is there any thing I can do to fix? Any one had this problem? If so how did yah fix it?
Thanks alot!

I AM STARTING TO HAVE THAT WITH MY LS 10 BOLT AND I TALKED TO MY LOCAL DEALER AND THEY SAID THAT THE LIMITED SLIP CLUTCHES IN THE REAR END WEAR OUT AFTER A WHILE.. YOU NEED TO REPLACE YOUR CLUTCHES OR JUST GET A NEW POSI UNIT .. THAT WILL BE CHEAPER AND GET MORE STOUT GEARS.. YOU WILL FEEL A DIFFERENCE IN TORQUE AND TAKEOFF. HAVE FUN..

I'm rebuilding the 9 bolt now, here's what i've found. (you might want to open yours up to check)
PARTS ARE NON EXISTANT
the dealer only sells the posi unit as a whole @ $1000+ you can get spider gears and i think side gears and a spring kit that's all i've been able to find (correct me if i'm wrong cuz i still need parts).
what i did was, first, read the tech article on this board about them (https://www.thirdgen.org/newdesign/tech/9boltservice.shtml). when i opened up the posi unit i found that my cones were just starting to bottom out, you can tell by the wear marks. Since new cones are unavailable i took my existing cones and housings to a machine shop, neighbor lucky me. We cut the outer edge and the center near the splines down so the cone would contact the sides again and not bottom out. We cut one down .090" and the other only needed .070". Now to get the correct shim combination and we'll be good as new again.
no more chicken leg for me!!!
P.S. 9 bolts don't have clutches only friction cones.....
