How much gear lube in the rear and front diff.
Just because they do doesn't mean it's the best thing. How many people get things and then change them right after they get it because it's far superior than factory.....Too many.ford puts Synthetic in it from factory. Choose as you wish... But fill til it starts coming out of the fill hole. once stops dripping or coming out stick plug back in
redline and some others already contain the additive.Did i say anything about it was being the best? No. I was stating that ford does things for a reason. Also your false on the additives thing. LSD's still need the friction modifier or you will have a popping and what not in the clutches and will lead to failure. especially with just straight gear oil.
