However, if you're determined to do it yourself, here's a general outline. Remember, this is a *general* guide; specifics may vary depending on your engine and modifications. Always consult a repair manual specific to your 1999 Dodge Durango and engine for precise instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Repair manual: Absolutely essential.
* Socket set and wrenches: Various sizes.
* Torque wrench: Crucial for proper tightening.
* Pliers: Various types.
* Drain pan: For power steering fluid.
* New power steering pump: Ensure it's the correct one for your Durango.
* New power steering fluid: Use the type specified in your owner's manual.
* New power steering belt (if needed): Often advisable to replace when changing the pump.
* Jack and jack stands: To safely lift the vehicle.
* Wheel chocks: For safety.
* Ratchet and extensions: To reach tight spots.
General Steps (Consult your repair manual for precise details and torque specs):
1. Safety First: Disconnect the negative battery terminal. Secure the vehicle with jack stands after properly jacking it up. Use wheel chocks.
2. Drain Power Steering Fluid: Locate the power steering fluid reservoir and carefully drain the fluid into a drain pan.
3. Remove Old Pump: This will involve removing the power steering belt (using a belt wrench or similar tool), disconnecting the pressure and return lines (carefully; fluid will likely leak), and unbolting the pump from its mounting bracket. Note the position of all components and hoses for reassembly.
4. Install New Pump: Carefully install the new power steering pump, ensuring it's correctly aligned with its mounting bracket. Tighten the bolts to the manufacturer's specifications (using your torque wrench).
5. Reconnect Lines: Carefully reconnect the pressure and return lines, ensuring they are securely attached and leak-free.
6. Install New Belt (if needed): Route the new power steering belt correctly around the pulleys.
7. Fill with Fluid: Add new power steering fluid to the reservoir, checking the level frequently. Start the engine, turn the steering wheel from lock to lock several times, and check the fluid level again, adding more as needed. Look for leaks.
8. Check for Leaks: Carefully inspect all connections for leaks.
9. Test Drive: Take the vehicle for a short test drive to ensure the power steering is working correctly.
Important Considerations:
* Bleeding the System: Some power steering systems require bleeding after installation. Your repair manual will detail this if necessary.
* Type of Fluid: Use the correct type of power steering fluid. Using the wrong fluid can damage the system.
* Torque Specifications: Incorrect torque can damage the pump or its mounting. Use your torque wrench and follow the specifications in your repair manual.
Again, this is a simplified overview. Refer to your vehicle's repair manual for detailed instructions and specific torque values. If you're not comfortable with any of these steps, seek professional help. Improperly installing a power steering pump can lead to serious damage or injury.
