If you're determined to tackle it yourself, here's a breakdown of the process:
1. Diagnosis:
* Pinpoint the leak: Carefully inspect the power steering unit for wet spots, dripping fluid, or trails of power steering fluid. The leak could originate from the pump itself, the pressure lines, the return lines, or the seals within the unit. A bright light and a clean rag can help.
* Check fluid level: Low power steering fluid is a strong indicator of a leak. Check the fluid reservoir and note its level.
2. Gathering Supplies and Tools:
* New power steering pump seals (or a rebuilt pump): This is the most likely source of the leak. You'll need the correct seals for your specific AU Falcon model year. A complete rebuilt pump might be simpler than sourcing and replacing individual seals.
* Power steering fluid: Use the correct type specified in your owner's manual.
* Wrench set (metric): You'll need a variety of sizes to remove bolts and fittings.
* Socket set (metric): For easier access to some bolts.
* Torque wrench: Essential to tighten bolts to the correct specifications to prevent damage.
* Drain pan: To catch the power steering fluid.
* Shop rags: For cleaning up spills.
* Gloves: To protect your hands.
* New power steering fluid reservoir cap (optional): If the old cap is damaged.
* Possibly a power steering pressure gauge (optional but helpful): This helps verify proper pump operation once you're done.
3. Repair Procedure (General Steps):
This is a simplified version. Consult a repair manual specific to your AU Falcon model year for detailed instructions and torque specifications. Improper torque can lead to serious damage.
* Disconnect the battery: This is a crucial safety step to prevent electrical shorts.
* Drain the power steering fluid: Locate the drain plug on the power steering fluid reservoir and carefully drain the fluid into a drain pan.
* Remove the power steering pump belt: Depending on the setup, this might involve removing other components.
* Disconnect power steering lines: Be prepared for some fluid spillage. Use appropriately sized wrenches and support the lines to avoid damaging them. Carefully label or take photos to remember how they go back.
* Remove the power steering pump: This usually involves removing several bolts. Again, note how it's connected before removal.
* Replace seals (or install rebuilt pump): If replacing seals, carefully follow the instructions that come with the seals. Use the appropriate sealant where necessary. If installing a rebuilt pump, follow the instructions provided with it.
* Reinstall the power steering pump: Reverse the removal process carefully, ensuring all bolts are correctly tightened to the manufacturer's specifications using a torque wrench.
* Reconnect power steering lines: Ensure connections are secure and tight.
* Reconnect the power steering pump belt: Ensure proper belt tension.
* Refill power steering fluid reservoir: Add the correct type of power steering fluid to the recommended level.
* Reconnect the battery:
* Start the engine: Check for leaks. Run the engine for a few minutes, turning the steering wheel from lock to lock several times to work the fluid and check for leaks. Top off the fluid reservoir as needed.
Important Considerations:
* Repair manual: A repair manual specific to your AU Falcon's year and model is essential. It will provide detailed instructions, torque specifications, and diagrams.
* Safety: Always work in a well-ventilated area. Power steering fluid is harmful if ingested or comes into contact with skin. Wear gloves and eye protection.
* Professional help: If you're uncomfortable performing this repair, take your vehicle to a qualified mechanic. The cost of a professional repair might be less than the cost of further damage from an improperly completed repair.
