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 SAE 80W-90 gear lubricant.
- Lubricant for axles intended for heavy-duty or trailer tow use is SAE 75W-140 SYNTHETIC gear lubricant.

Trac-lok differentials require the addition of 4 oz. of friction modifier to the axle lubricant. The 194 RBI axle lubricant capacity is 1.66 liters (3.50 pints) total, including the friction modifier if necessary.

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