yukon 3.73s
I've done several gear swaps before in many different types of rears and 4x4 fronts. This time around I just could not get both coast and drive patterns right.
I eventually took notes on shim sizes in every location, what the pattern looked like with each change, etc. And used GM yellow compound.
Usually I like to get it perfect, I just got these as close as possible and it seemed to have worked.
