Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure it is in gear or the parking brake is engaged.
Disconnect the negative battery terminal for electrical safety.

2. Inspect and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
Using a turkey baster or siphon, remove old fluid and inspect for metal shavings or debris.
Replace with the manufacturer-recommended power steering fluid (typically ATF or a specific PS fluid).
Reinstall the cap and start the engine to circulate fluid. Check for leaks.

3. Wheel Bearing Inspection and Replacement

Lift the front of the vehicle using a jack and secure with jack stands.
Remove the front wheels.
Inspect the wheel bearings by spinning the hub; listen for grinding or roughness.
If faulty, remove the hub assembly and replace the wheel bearings using a bearing puller. Reassemble in reverse order.

4. CV Joint Inspection and Replacement

Inspect the CV joint boots for cracks or grease leaks.
If the boot is damaged, replace the entire axle if the joint is also compromised.
To replace, remove the axle nut, detach the lower control arm, and pull the axle out of the transmission and hub.

5. Suspension Component Inspection

Visually check struts, shocks, and control arms for wear or damage.
Replace any worn bushings or components as needed. Ensure all bolts are torqued to the manufacturer specifications.
