Dodge Durango 2004-2009 Drivetrain Specifications

The 2004-2009 Dodge Durango offers two drivetrain options: rear-wheel drive (RWD) and all-wheel drive (AWD). The RWD is standard, while the AWD system is optional and provides enhanced traction and stability in various driving conditions. Both drivetrains are compatible with the 3.7L V6, 4.7L V8, and 5.7L HEMI V8 engines, depending on the trim level and model year.

Regular maintenance for the Durango's drivetrain includes checking and replacing the transfer case fluid every 30,000 miles, inspecting the driveshaft and U-joints for wear, and ensuring the differential fluid is changed every 50,000 miles. For AWD models, the front and rear differentials and the transfer case should be serviced according to the manufacturer's recommendations to maintain optimal performance.

To replace the driveshaft, first, secure the vehicle on a lift or jack stands. Remove the bolts connecting the driveshaft to the differential and transfer case. Mark the driveshaft orientation for proper reinstallation. Slide the old driveshaft out and install the new one, aligning the marks. Reattach the bolts and torque them to the manufacturer's specifications. Finally, test the vehicle to ensure proper operation.

If the AWD system fails to engage, check the transfer case fluid level and condition. Inspect the AWD control module and wiring for damage or loose connections. Ensure the tires are of the same size and tread depth, as mismatched tires can prevent proper AWD operation. If issues persist, use a diagnostic scanner to check for error codes and consult a professional mechanic.

To optimize drivetrain performance, use high-quality synthetic fluids for the differentials and transfer case. Regularly inspect and replace worn components like U-joints and CV axles. Ensure proper tire alignment and rotation to reduce strain on the drivetrain. For AWD models, avoid excessive towing or off-road use without proper maintenance to prevent premature wear.
