I will be running a Ford 9 inch with posi. My shortnened/reconditioned rear-end came with a bottle of motorcraft additve friction modifier.
1.Does this stuff really help quiet the gears?
2.Anyone have experience with this product who can comment?
3. MOST IMPORTANTLY, HOW MUCH DO I ADD TO THE DIFFERENTIAL FLUID?
APPRECIATE ANY COMMENTS FROM EXPERIENCED BUILDERS, THIS IS MY FIRST BUILD.
