Do you or don't you put limited slip additive when you change your rear axle fluid on these new trucks. Keep getting conflicting answers about this one.

    First off, check to see what the owner's manual states. Secondly, read the label on the bottle of gear lube. Some brands already have the additive in it.

    99+ chevys do not use the additive. They use a synthetic lube

    If you change over to a good synthetic, like Amsoil, don't add anything to it. The Amsoil is already more slippery than the original with the additive.

    Use about 1:1 of gear oil and super glue and it will help your LSD grip a whole lot better in limited-traction situations. Next best thing to a locker if you ask me. :)

    If we are talking about GM part # 1052358 - it is only needed with the old style limited slip differential. The new trucks have a different style of locker.

    This may be more than you want to know - but the reason the additive was called for was to help disengage (un-lock) the clutch. Without the additive when you came to a stop it felt like a car behind you tapped your rear bumper. I recall looking in the rear view expecting to see a VW bug stuck to my bumper - sometimes you needed two bottles of the additive to stop the problem.
