With the 1998 model year, the axle lube in the 8 1/2 and 9 1/4 axles was changed in formulation to improve fuel economy. When adding lube or if service is performed that requires new lube, use 75W90 part # 5010320AA.
This lube is more aggressive toward RTV sealants than previously used axle lubes. When resealing the axle cover, using proper sealing material to minimize any potential fluid foaming and/or seal breakdown is important. Currently the only recommended sealing material for all axle covers or transmission pans is Mopar RTV Sealant, gray in color, part # 82300234.
