* Specific Dana 44 variant: There are many variations of the Dana 44, and some might have slightly different capacities. The year, model of Jeep, and axle specifics (e.g., is it a front or rear axle, what's the ratio?) will determine the precise capacity.
* Whether it's a limited-slip differential (LSD): LSDs often require a specific type of gear oil formulated for their operation.
Generally speaking:
* Gear Oil Type: For most applications, a 75W-90 gear oil meeting GL-5 specifications is suitable. For a limited-slip differential, you'll need to use a gear oil that's compatible with the LSD additive package (often specified as a friction modifier). Check your owner's manual or the axle's identification tag for the manufacturer's recommendation. Some modern vehicles might call for synthetic gear oil.
* Quantity: A Dana 44 axle typically holds between 1.5 to 2 quarts (1.4 to 1.9 liters) of gear oil. However, this is an approximation. You absolutely must consult your Jeep's owner's manual or a reputable repair manual specific to your vehicle's year, make, and model to get the precise capacity. Overfilling or underfilling can damage the axle.
Finding the Correct Information:
1. Owner's Manual: This is your best source. Look for the section on maintenance or differentials.
2. Axle Tag: The axle housing usually has an identification tag with specifications including the gear ratio. This can help you find the correct information online or from a parts supplier.
3. Jeep Repair Manual: A Haynes or Chilton manual for your specific Jeep model will provide detailed information on gear oil capacity and type.
4. Parts Store: Provide the year, make, and model of your Jeep and the axle identification to a knowledgeable parts professional. They can look up the correct gear oil type and quantity.
Caution: Never assume the capacity. Always double-check before changing your gear oil. Incorrect oil can seriously damage your axle.
