I do most of the work myself on my pickup truck. Typical shade tree mechanic.
Last year I did not like the looks of the rear differential cover. It looked like the metal was getting too thin due to corrosion so I decided to replace it with a new one. Of course i replaced it with the specified oil, deciding to go with AmsOil synthetic. More then one person told me I did not need to use a slip lock additive so I did not use it.
Now I am getting a chatter from the rear end when I make sharp right or left hand turns. Obviously the clutches are slipping or chattering so next nice day I am going to have to get 4 oz of fluid out of the diff and add the slip lock additive then go do a bunch of figure 8's and hopefully stop this issue.
Moral of the story, put the additive in from day one. Extra lube cannot hurt.
