Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; top off if low using the manufacturer-recommended fluid.
Inspect fluid for contamination or burning smell; replace if necessary.

3. Inspect CV Joints

Jack up the front of the vehicle and secure it on jack stands.
Remove the front wheel for better access to the CV joint.
Visually inspect the CV boot for tears or grease leakage.
Wiggle the axle to check for excessive play; replace the CV joint if damaged.

4. Inspect Wheel Bearings

With the wheel removed, grasp the wheel hub and shake it side to side.
Listen for grinding noises and check for excessive movement.
If worn, remove the hub assembly and replace the wheel bearings.

5. Examine Suspension Components

Inspect the struts and shock absorbers for leaks or damage.
Check all control arm bushings for wear or cracking.
Tighten any loose bolts to the manufacturer’s torque specifications.
Replace any worn suspension components.
