Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during inspection.

2. Inspect and Replace Power Steering Components

Check Power Steering Fluid:
- Remove the power steering fluid reservoir cap and inspect the fluid level.
- If low, top off with the recommended fluid type (Toyota ATF or equivalent).
Inspect Steering Components:
- Use a jack to lift the vehicle and support it securely with jack stands.
- Examine the tie rods and ball joints for signs of wear or damage.
- If any components are worn, remove the affected part using a socket set.
Replace Damaged Components:
- If the tie rod ends are worn, replace them by removing the cotter pin and nut, then disconnect the tie rod from the steering knuckle.
- Install the new tie rod end and secure it with the nut and cotter pin, ensuring proper torque (typically 50-70 ft-lbs).
Wheel Bearing Inspection:
- Spin the wheel to check for grinding noise or roughness.
- If the wheel bearing is faulty, remove the wheel and hub assembly.
- Replace the wheel bearing and reassemble.
Final Assembly:
- Reinstall any removed components, ensuring all bolts are torqued to specifications.
- Refill the power steering fluid, if necessary.

3. Test Drive

Reconnect the battery.
Start the vehicle and turn the steering wheel left and right to check for any noise.
Test drive the vehicle to ensure the grinding noise is eliminated.
