sure grip problems

[pink340]

Hey Guys I picked up a new third member 742 case, sure grip and 3;23's $250 didn't think that was bad.. anyway I put it in the cuda. And It seems tight... way to tight It acts like a spool. when I turn a corner the wheels will chirp and the back of the car will bounce and shimmy a little. So I pulled it out and took it apart.. I have a maual and it shows there being 5 clutch plates on each side.. mine has the 5 plates but each side also has a thin shim.. could somebody have put these in to tighten it up?? do you think If I were to take the shims out it would help my problem?  thanks Brandon

possibly you just needed the additive to the oil to allow it to slip without chattering

[pink340]

what kind of oil would you suggest? and what kind of a additive ?

thanks

u will need limited slip additive(friction modifier) part # 04318060ab.  yes that shim is factory, it is used against the  axel gear.

Is it best to use regular 80w 90... over like 75w90 synthetic??? Also Iv never seen this friction modifier.. can I get it from chrysler?

I use 75-90 synthetic
Mopar & most parts tores will have the additive
