Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the "Min" and "Max" marks.
If low, add the appropriate power steering fluid as specified in the owner’s manual.
Replace the cap securely.

3. Inspect and Replace Power Steering Pump (if needed)

Drain the power steering fluid by removing the return line from the pump.
Disconnect the pump from the mounting bracket using a socket set.
Remove the pump from the vehicle and replace it with a new one.
Reconnect the return line and refill the power steering fluid.

4. Inspect Steering Rack (if needed)

Remove the plastic cover under the steering column to access the steering rack.
Check for any visible leaks or damage to the steering rack.
If damage is found, remove the steering rack by disconnecting the tie rod ends and mounting bolts.
Install the new steering rack and reconnect all components.

5. Inspect and Replace Wheel Bearings (if needed)

Lift the vehicle and remove the front wheel.
Inspect the wheel bearing for play or roughness by spinning the hub.
If damaged, remove the brake caliper and rotor to access the wheel bearing.
Replace the wheel bearing and reassemble all components.
