Rear Diff. Fluid Help!
I have a 96 F150 with a 302. It way past time to change my front and rear diff. fluids, but I'm not sure what type of fluids I need. Does anyone know how I can tell if I have Limited Slip or if I need extra additives. How much product sound I need to buy for each diff.

There should be a little tag on your differential cover, with some numbers. Those numbers will tell you what kind of rear end you have. Most likely youll need 75 or 80w-90 gear oil. Your owners manual will tell you for sure.
