Don,
Don't believe the fact that GL5 is ok to use! It is not! Any gear box or diff. that has "Yellow metal" (brass/bronze) parts will be affected in a bad way. Find a distributor of bulk oil and grease and they will sell 5 gallon pails of GL4 grease, which is ok to use. I would stick to 140 weight for diff. Do a search on the net for explanation of GL5 use. I found GL4 85-90 weight for the trans at a local NAPA store, Sta Lube/CRC brand I think. It's out there, don't give up.
