hey all... well my engine is set with the valvoline max life, the trans just got mobil 1 ATF... all that's left is within the next month or two to do a differential fluid change... what do you guys run and what additives do I need to do the best job. I figure I'll replace the cover gasket and maybe paint it black while I have it off too

but since I got the engine and trans set, I figure I should do the diff. soon too

thanks in advance

all right... do you just put that fluid in and call it a day? I know with the "ford traction lok" rear axle, there is an additive required... is that already in the royal purple stuff?

 

put it in and call it a day! your track lock will live happyer.
