Some 2007 and newer vehicles may need to have material removed from the backside of the case to clear the housing. Yukon recommends the use of high grade GL-5 gear oil and Yukon LSD (Limited Slip Differential) additive for long life and smooth operation. Part number OILADD. The use of synthetic oil is allowed but may result in aggressive or noisy operation.
