Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Check and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level.
If low, add the recommended power steering fluid type until it reaches the appropriate level.

3. Inspect and Replace Steering Components

Using a jack, lift the front of the vehicle securely on jack stands.
Remove the front wheels to gain access to steering components.
Inspect the tie rods and ball joints for wear. Replace any damaged components.
Torque new tie rods and ball joints to manufacturer specifications (typically around 30-40 ft-lbs, but check the service manual for specifics).

4. Wheel Bearing Inspection and Replacement

Spin each wheel by hand and listen for grinding or rough noises.
If a wheel bearing is suspected, remove the brake caliper and rotor.
Unbolt the wheel bearing assembly and replace it with a new one, torquing to manufacturer specifications (usually around 80-100 ft-lbs).

5. Reassemble and Lower Vehicle

Reinstall the brake rotor and caliper.
Replace the front wheels and torque lug nuts to the correct specification (usually 140-160 ft-lbs).
Lower the vehicle back to the ground and reconnect the battery.
