Just changed the rear diff oil on my 96 and had a question on the friction modifier. It is just the regualr stock rearend (not LS-jacked it up and put it in neutral and 1 tire spun 1 way and the other the other way). Added the 80/90 as recommended by the owners manual. Does it still need the friction modifier? I am sure it will not hurt if I do add it, better to be safe than sorry. Any thoughts?

you don't need it.

No, the friction modifier is for vehicles equipped with an anti-spin differential, if yours spun forwards and backwards, then you have an open rear end and do no the need the friction modifier. Its purpose if to reduce friction so that the anti-spin clutches can slip.

If I did add it would it hurt it would it? I already bought it but have not put in yet. Any anti friction addative would help I would think.

No, you could add it and it would be fine. Couldn't hurt.
