Lubricant

DESCRIPTION

CAUTION: The Use Of Petroleum Based Rear Axle Lubricants May Cause Premature Axle Failure.

NOTE: Refer to Maintenance or the vehicle owner's manual for recommended maintenance intervals.

The lubricant recommended for this differential is Mopar Synthetic Gear & Axle Lubricant 75W-140 (MS-8985). A container of Mopar Limited Slip Additive (MS-5630) should also be added during a lubricant change.

Vehicle design limits the amount of cooling air flow to the Viper rear axle. This limited air flow combined with high-performance operation causes temperatures within the axle to easily reach as high as 300°F (149°C). Conventional petroleum based axle lubricants are proven to break down under these conditions, causing excessive wear, noise, and premature axle failure. Only synthetic axle lubricant provides optimum protection and durability under extreme temperatures.

LUBRICANT LEVEL/CAPACITY
The differential lubricant level should be inspected every 12 months/7500 miles or at each engine oil change, which ever comes first.

The lubricant level should be checked with the vehicle in a level position. The lubricant level should not be lower than 6.4 mm (1/4 inch) below the fill hole.

Differential lubricant service should be performed regularly. Refer to Maintenance, or the vehicle owner's manual for recommended maintenance intervals.

The differential lubricant capacity is 45 fl. oz., including four ounces of friction modifier. Do not overfill the differential. This can cause the lubricant to foam and/or overheat, and may cause differential leaks.

CAUTION: If the rear axle has been submerged in water, the axle lubricant must be checked for water contamination immediately. Water contaminated lubricant could cause premature axle failure.
