Safety First:
* Disconnect the negative battery terminal before starting any work on the vehicle's electrical system.
* Use jack stands to securely support the vehicle. Never work under a vehicle supported only by a jack.
* Wear safety glasses and gloves.
Tools You'll Need:
* Jack and jack stands: To safely lift and support the vehicle.
* Wheel chocks: To prevent the vehicle from rolling.
* Socket wrench set: Various sizes, including metric and possibly SAE.
* Ratcheting wrenches: For easier access in tight spaces.
* Torque wrench: Essential for properly tightening bolts to prevent damage.
* Engine hoist (highly recommended): Makes the job significantly easier and safer. While you *might* be able to support the engine with a strong jack, an engine hoist is the preferred method.
* Pry bar or large screwdriver: To help break loose rusted or stubborn bolts.
* Penetrating oil (like PB Blaster): To loosen rusted bolts. Apply generously and let it soak for a while before attempting to remove them.
* New motor mounts: Make sure you get the correct mounts for your specific Durango model and engine.
* Shop rags or towels: To keep things clean and prevent scratches.
General Steps (This is a simplified overview. Refer to a repair manual for detailed instructions):
1. Preparation: Raise the vehicle securely using the jack and jack stands. Place wheel chocks on the wheels that remain on the ground. Disconnect the negative battery terminal.
2. Access the Motor Mounts: Locate the motor mounts. There are typically three – one on each side of the engine and one in the front or rear (depending on the engine). You'll need to remove various components to access them. This may include:
* Air intake system: Disconnect and move out of the way.
* Exhaust components: Possibly some exhaust components may need to be loosened or removed for better access.
* Wiring harnesses: Carefully disconnect any wiring harnesses connected to the area. Take photos to help with reassembly.
* Other components: Depending on the specific mount location, you may have to remove other parts.
3. Remove the Old Motor Mounts: Use the appropriate sockets and wrenches to remove the bolts securing the old motor mounts to the engine and the chassis. Penetrating oil will likely be your best friend here. They can be very stubborn.
4. Support the Engine: This is crucial. Before completely removing the old mounts, use an engine hoist to support the engine's weight. If you're not using an engine hoist, you'll need a very strong jack strategically placed to support the weight of the engine as you remove the mounts. Failing to do this properly could result in serious injury or engine damage.
5. Install the New Motor Mounts: Install the new motor mounts, ensuring they're properly seated and aligned. Tighten the bolts to the manufacturer's specified torque specifications (found in your repair manual).
6. Reconnect and Reassemble: Carefully reconnect all the components you removed earlier. Double-check everything before lowering the vehicle.
7. Lower the Vehicle: Slowly lower the vehicle using the jack.
8. Reconnect Battery Terminal: Reconnect the negative battery terminal.
9. Test: Start the engine and check for any unusual noises or vibrations. Test drive the vehicle to ensure the mounts are functioning correctly.
Important Considerations:
* Repair Manual: A factory service manual or a reputable repair guide specific to your 2002 Dodge Durango is essential. It provides detailed instructions, torque specifications, and diagrams.
* Difficulty: This is not a beginner's job. If you're not comfortable working on vehicles, consider taking it to a qualified mechanic. Improper installation can lead to serious damage.
* Engine Hoist: An engine hoist is highly recommended to make this job safer and easier.
This information is for guidance only. Always consult your repair manual for specific instructions and safety precautions. Improperly performing this repair can lead to serious injury or damage to your vehicle. If you are not comfortable with this type of repair, seek the help of a qualified mechanic.
