Solution

1. Preparation

Gather tools: jack stands, socket set, torque wrench, fluid pump, and safety glasses.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect and Replace Power Steering Fluid

Check Fluid Level: Open the power steering reservoir cap and check the fluid level; top off with manufacturer-recommended fluid if low.
Fluid Condition: If the fluid is dark or contaminated, drain and replace it.
Fluid Replacement: Use a fluid pump to remove old fluid, then refill with new fluid while turning the wheel side to side to purge air from the system.

3. Inspect Steering Components

Visual Inspection: Check tie rods and ball joints for play or wear; replace if necessary.
Check Steering Rack: Inspect for leaks or signs of damage; replace if faulty.
Tighten Components: Ensure all bolts and nuts are torqued to manufacturer specifications.

4. Replace Power Steering Pump (if necessary)

Remove Pump: Disconnect the power steering lines, unbolt the pump from its mount, and remove.
Install New Pump: Position the new pump and tighten bolts to manufacturer torque specifications.
Reconnect Lines: Ensure all power steering lines are securely fastened.

5. Reassemble and Test

Reinstall any components removed for access.
Ensure all tools are removed from the engine bay.
Test the vehicle by turning the steering wheel to check for grinding noise.
