Thanks Geno, I knew I could order it but since Summit dont carry it I didnt see a reason to go pay shipping on the stuff when a local synthetic and friction modifier would be less expensive. I would order it if I could use it by itself but you did say if the diff does chatter or whine then I could add some FM. That tells me that sometimes you have had to add some when using the Amsoil and with my luck I would have to as well.
So for gear oil I need 75w90 and I only need one quart?
But as to my other question, if the diff has new bearings and the gears come with the ring bolts/pinion nut/pinion seal/crush sleeve/shims/inner bearing and I am gonna use RTV then I dont need that $90 kit right? I will have everything except the outer pinion bearing and carrier shims, no?
