Lubrication

A multi-purpose, hypoid gear lubricant which conforms to the following specifications should be used. MOPAR Hypoid Gear Lubricant conforms to all of these specifications.
- The lubricant should have MIL-L-2105C and API GL 5 quality specifications.
- Lubricant is a thermally stable SAY 90W gear lubricant.

Trac-lok differentials require the addition of 0.18 L (6 ounces) of friction modifier to the axle lubricant. The 248 RBI axle lubricant capacity is 2.96 liters (6.25 pints) total, including the friction modifier if necessary.

Power-lok differentials require the addition of 0.24 liters (8 ounces) of friction modifier to the axle lubricant. The 267 RBI axle lubricant capacity is 3.31 liters (7.0 pints) total, including the friction modifier.

CAUTION: If axle is submerged in water, lubricant must be replaced immediately to avoid possible premature axle failure.
