Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shocks during repairs.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top up with the manufacturer-recommended fluid if necessary.
Inspect fluid for contamination (milky appearance indicates water intrusion).

3. Inspect Power Steering Components

Steering Rack:
- Visually inspect the steering rack for leaks or signs of wear.
- If damaged, proceed to replace the steering rack.
Tie Rods and Ball Joints:
- Check for play by wiggling the tie rods and ball joints.
- If excessive play is found, replace the affected components.

4. Test Power Steering Pump

Reconnect the battery and start the engine.
Observe the power steering pump for noise or vibration.
If the pump is malfunctioning, replace it according to manufacturer specifications.

5. Alignment Check

After components are replaced, perform a wheel alignment to ensure proper steering geometry.
Torque specifications for tie rod ends and other suspension components should be adhered to, typically around 50-70 lb-ft.
