Tools and Materials You'll Need:
* New power steering fluid: Use the type recommended in your owner's manual (usually ATF+4 for this year). Buy enough to completely flush the system.
* Funnel: A small funnel that fits the power steering reservoir.
* New power steering reservoir cap: It's a good idea to replace this since it's likely to be worn.
* Wrench(es): You'll need the correct size wrench to loosen the power steering return line fitting (likely a 10mm, 12mm or 13mm. Consult your repair manual). You may also need wrenches to access the drain plug, if one is present on your power steering pump.
* Drain pan: To catch the old fluid.
* Jack and jack stands (or ramps): For easier access to the power steering components. Safety first! Always support your vehicle properly.
* Gloves: Power steering fluid is messy and can irritate your skin.
* Clean rags or shop towels: For cleanup.
* Tube/hose (optional): To siphon out fluid without completely draining the reservoir.
* Power steering fluid flush kit (optional): Makes the process easier and more thorough.
Procedure (General - Consult Your Owner's Manual):
1. Prepare the vehicle: Park on a level surface, engage the parking brake, and secure the vehicle with jack stands if lifting.
2. Locate the power steering reservoir: It's usually a plastic reservoir near the engine. Consult your owner's manual for the exact location.
3. Check fluid level: Note the current fluid level.
4. Drain the old fluid: There are two main methods:
* Siphon method (preferred for less mess): Use a siphon tube to carefully remove as much old fluid as possible from the reservoir.
* Drain method: If your pump has a drain plug, carefully loosen and remove it to drain the old fluid into your drain pan. Otherwise, you may have to drain from the return line.
5. Locate the return line: This is the line that returns fluid from the steering gear to the reservoir. Locate the fitting on the return line and carefully loosen it. Be aware that some fluid will likely spill out. Have a drain pan ready.
6. Flush the system (Optional but Recommended): With the return line disconnected, have a helper turn the steering wheel from lock to lock several times while you add new fluid to the reservoir. The old fluid will come out of the return line. Continue until the fluid coming out is clear. Using a power steering fluid flush kit makes this step much easier.
7. Reconnect the return line: Once the fluid is clean, tighten the fitting securely to the return line.
8. Refill the reservoir: Add new power steering fluid to the reservoir, following the "fill to" line indicated on the reservoir.
9. Start the engine: Run the engine for a few minutes. Check the fluid level and add more fluid if needed.
10. Check for leaks: Inspect the connections and lines for any leaks.
11. Top off the fluid: Add fluid as necessary until it reaches the proper level.
12. Test the steering: Drive the vehicle and test the power steering. Make sure there are no leaks and the steering feels smooth.
Important Notes:
* Safety first: Always use jack stands when working under your vehicle.
* Fluid type: Use only the recommended power steering fluid for your vehicle. Using the incorrect fluid can damage the system.
* Disposal: Dispose of the old power steering fluid properly according to your local regulations. It is harmful to the environment.
* Consult your owner's manual: This is crucial for accurate information and specific steps for your 2002 Dodge Durango.
If you're not comfortable performing this task yourself, it's best to take your Durango to a qualified mechanic. They have the tools and expertise to do the job correctly and safely.
