how many quarts of gear oil fill up the dana 44 in my front axle and the 12 bolt limited slip corp in the rear axle? my manual doesn't say, schuck's can't tell me, Napa couldn't even find me the gaskets (dumbasses). Trying to save an extra trip or having extra gear oil when i remove diff covers, clean and re-fill this weekend. Any recommendations on a limited slip additive? damn i can hardly wait for my driveline to come (yes, high angle, Jesse is the man) SOON I WILL WHEEL!
