    I have no clue. But I want to try and keep this one in working order since it has 3:73's in it. /forums/images/icons/smile.gif All I want to do is open it up clean it out and service it. I want to take this truck to Paragon in 2 weeks.

    You do not need to use a limited slip additive with a Gov-lock!

    Right after I bought my truck, I changed the gear oil in the rear, and did not put the additive in. Two weeks later, at 30 MPH on dry asphalt, going straight, KABLOW!!!! Rear wheels locked up and came to a screeching halt. Thank God it happened then on not on the freeway! I would put the additive in now, but I've got an open carrier.

    This failure was not due to the lack of LS additive. No additive is required with a Gov-lock!

    Why do the Chiltons/Haynes manuals say you do? I'm not at all familiar with the Gov Lok, just curious why a repair manual would tell you to put additive in if it were unnecessary? I do know that alot of the stuff those sh!tty manuals say is inaccurate, but not all of it.

    They are either wrong, or they are confusing the Gov-lock with a regular limited slip which was used in GM 4X4s prior to the introduction of the Gov-lock. Gov-locks do not use additive.
