Hi, Is there a breaking-in procedure that needs to be done if new differential gears are installed? is there a need for a special oil to be used? Thanks!

Yes very important to not over heat the gears. When new, the gear mating surfaces are rough and heat up quicky. If they get too hot it ruins the heat treatment of the gears and they will then wear out faster. I also change the oil often during the break-in.

ok this brings up a ?what type /weight of oil do you use- i use 85-140, what effect does this have??
i have new lockers and just drove them , yes i did change out the gear oil about 500 miles and i just did it now (trying to figure out how to do the transfer case)
