Before you begin:
* Consult a repair manual: A Haynes or Chilton manual specific to your 2005 Ford Focus is crucial. It will provide detailed instructions, diagrams, torque specifications, and crucial warnings specific to your vehicle's model. This is not a job to wing.
* Gather tools: You'll need various wrenches (likely metric), pliers, possibly a hose clamp tool, a catch pan for the power steering fluid, new power steering fluid (matching your car's specifications – check your manual), rags, safety glasses, gloves, and potentially a torque wrench.
* Jack and stands: Securely jack up the car and support it with jack stands. Never work under a car supported only by a jack.
* Safety First: Wear safety glasses and gloves. Power steering fluid is corrosive and can cause skin irritation. Be prepared for fluid spillage.
General Steps (This is a generalized outline; your specific Focus may vary):
1. Locate the Hose: Identify the high-pressure power steering hose that needs replacement. Your repair manual will show you its location and routing.
2. Drain Some Fluid: Slightly loosen the cap on the power steering fluid reservoir to relieve pressure before disconnecting any lines. You might need to drain some fluid from the reservoir to make the job easier.
3. Disconnect the Hose: This is usually the hardest part. The hose likely connects to the power steering pump and the steering rack. You'll likely need wrenches to remove fitting clamps or nuts. Be prepared for fluid to spurt out under pressure. Have your catch pan ready. Use rags to absorb spills immediately.
4. Remove the Old Hose: Carefully remove the old hose from its clamps and routing. Take note of how it was routed; you'll need to replicate this when installing the new hose.
5. Install the New Hose: Carefully route the new hose, ensuring it follows the same path as the old one. Avoid kinks or tight bends.
6. Connect the New Hose: Securely attach the new hose to the pump and rack using the appropriate clamps or nuts. Tighten them to the manufacturer's specifications (found in your repair manual).
7. Refill the Reservoir: Add new power steering fluid to the reservoir, checking the fluid level regularly.
8. Bleed the System (Possibly): Some systems may require bleeding after a high-pressure hose replacement to remove air bubbles. Your repair manual will tell you if this is necessary for your specific model. This usually involves turning the steering wheel lock-to-lock while the engine runs (with the reservoir topped off).
9. Test the System: Start the engine and check for leaks around the hose connections. Turn the steering wheel lock-to-lock a few times to check for smooth operation. Top off the fluid as needed.
Important Considerations:
* Type of Hose: Ensure you get the correct replacement hose for your 2005 Ford Focus. Using the wrong hose can lead to leaks or damage.
* Clamps: If using reusable hose clamps, make sure they are tightened properly. Replace if they are damaged.
* Fluid Type: Use only the correct type of power steering fluid specified for your vehicle.
Disclaimer: This is a general guide. Improperly performing this repair can lead to damage to your vehicle or personal injury. If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Always refer to your vehicle's repair manual for specific instructions and safety precautions.
