Sounds like the exact problem that i had when I changed my diff lube to the Lucas crap. I had tons of chatter from the limited slip. Id recommend changing to the ford 75-w140 with a bottle of the factory additive. Then check ur tires to see how they r worn. If mine get worn in one direction or if i had just rotated my tires ill get a little strange feeling like that.
I only noticed that with my BFG all terrains but never with the OEM Goodyears.
