Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Refill Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; if low, refill with the manufacturer's recommended fluid type.
Inspect for signs of contamination in the fluid.

3. Check Suspension Components

Lift the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the control arms, ball joints, and bushings for any signs of wear or damage.
If any components are worn, replace them with OEM or quality aftermarket parts.

4. Inspect Steering Rack

Check for any leaks around the steering rack and pinion assembly.
If the steering rack is damaged, remove it by disconnecting the steering linkage and fluid lines, then replace it with a new unit.

5. Wheel Bearing Inspection

Spin the front wheels to listen for any grinding noises.
If noise is present, remove the wheel and brake assembly, then use a socket set to remove the hub assembly.
Replace any worn or damaged wheel bearings.
