Your are correct! The cost of the current solution is the cost of a quart of differential lube and 1oz of limited slip additive. To replace the cover would cost 86 oz of lube and 4 oz slip additive and a new cover. Over $100 vs $15 x 57,000 trucks. With labor the cost difference is probably close to $12 million. I will probably add a new bung on top of the cover at change time and simply fill with the recommend amounts of fluid including the additional 19/1oz combo in the RRT.
