Here's why:
* Differing Axle Ratios: The amount of gear oil required depends on the specific axle ratio in your truck. You'll need to check your owner's manual or look for a sticker on the differential housing to find this information.
* Multiple Axles: Your 4WD Dakota has two differentials: the front and the rear. Each one will require a different amount of gear oil.
* Fluid Type: Make sure you use the correct type of gear oil for your truck. Consult your owner's manual or a reputable auto parts store for the recommended type.
How to Find the Right Information:
1. Check Your Owner's Manual: This is the most reliable source. It should list the correct oil type and capacity for each axle.
2. Look for an Axle Tag: The differential housing should have a tag indicating the axle ratio.
3. Consult an Auto Parts Store: Provide them with your vehicle's year, make, model, and engine size. They can look up the information for you.
4. Check Online Resources: Reputable online resources like the Haynes Repair Manual or specific car forums for your vehicle model can provide useful information.
Important Note: Never overfill your differentials. Too much fluid can lead to damage.
It's always best to refer to your owner's manual for the most accurate information regarding your vehicle's maintenance needs.
