Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; top off with the manufacturer-recommended fluid if low.
Inspect for any visible leaks around hoses and connections.

3. Inspect Steering Linkage

Use a socket set to remove any covers if necessary.
Check all tie rod ends and the steering rack for wear and secure fittings.
Replace any damaged or excessively worn components.

4. Examine CV Joints

Raise the front of the vehicle using a jack and secure with jack stands.
Inspect the CV joints for torn boots or excessive play; if damaged, replace with new CV joints.
Ensure that all clips and seals are properly secured.

5. Check Wheel Bearings

Spin the wheel by hand while listening for grinding noises; if heard, the wheel bearing may need replacement.
Use a torque wrench to remove the wheel assembly, then replace the wheel bearing as necessary, following manufacturer torque specifications.

6. Inspect Suspension Components

Examine control arms, struts, and bushings visually for any signs of wear or damage.
Replace any worn suspension parts to restore proper vehicle handling.
