Limited Slip Additive

I have a '98 5.9 limited with quadratrac, I was wondering if i need to use the limited slip additive in both of my diffs, just the rear, or not at all? Thanks for the help.

i've been told it doesn't hurt to add it if you don't know what to do...

repost Nazi's suck!

A guy walks into the psychiatrist office wearing only Glad Wrap shorts. The shrink says, "Well, I can clearly see you're nuts."

My haynes manual says;
Limited slip differential ................ Add MOPAR Friction Modifier.

I think the quadra-trac is limited slip both front and rear.

If anyone knows different please let us know .

The front end should be open. If you have the lsd in the back it wont hurt to add a friction modifier. All it really does is quite down and smooth out the diff.
