I'm an Amsoil user as well. When I can, I break in the gears and bearings with conventional fluid, just like an engine. I was also told that the OEM gear coatings are not good for the gears and bearings afterwards. So a flush to eliminate that as well as any initial metal wear seems like a good idea. Then I go to the Amsoil Severe Gear 75w-90 synthetic. I just checked my 8 3/4" gears after several years of running. They were much better than expected so I put them back in. Unfortunately, I have yet to count the # of runs I get on some of my parts.

If you have the gears REM surface finished, you won't have the coating to worry about. But it's best to set the gears up before REM because it can be difficult to get a pattern reading, according to my differential guy.
