When I replaced the axle bearings I changed the rear end lube out (80W90).
Thinking it couldnt hurt to add new gear lube and drain the old. But now Im
thinking of changing it again and going to a synthetic gear lube. I dont
believe there will be any problems with it. Dale A. also says to use
sythentic transmission fluid on the Ford 5 speed. I dont believe sythentic
gear lube normally used(gear lube)in the stock transmisson would create any
problems with the brass syncronizers or any other metals. Just my opinion.
