Rear diff fliud change
I'm planning to change the rear diff fluid on my '99 2WD, which is oozing fluid at the cover. I'm going to try to find some Permatex Gear Oil sealant, and Amsoil 75W90 synthetic gear lube. I have an open diff, not limited slip. Sound good? Any tips? I used blue RTV and 80W90 dino last time. I've been hearing rumors that Ford is now recommending a different weight? If so, can someone give me the TBS number?
Thanks,
Jim
