DISCUSSION:
With the introduction of the 1998 model year, the axle lubricant in the 8-1/4 and 9-1/4 axles was changed in formulation to improve fuel economy. When
adding lubricant or if service is performed that requires new lubricant use 75W90 p/n 5010320AA.
This lubricant is more aggressive toward RTV sealants than previously used axle lubricants. When resealing the axle cover, using the proper sealing
material to minimize any potential fluid foaming and/or seal breakdown is important. Currently the only recommended sealing material for mall axle
covers or transmission pans is MOPAR RTV Sealant (grey in color) p/n 82300234.
