Solution

1. Preparation

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

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Using a turkey baster or siphon, remove old fluid and dispose of it properly.
Refill the reservoir with the manufacturer-recommended power steering fluid.
Start the engine and turn the steering wheel from lock to lock to bleed the system. Check for leaks.

3. Inspect and Replace CV Joints

Raise the front of the vehicle using a jack and secure it on jack stands.
Remove the front wheels using a socket set.
Inspect the CV joints for any signs of wear, such as torn boots or excessive play.
If damaged, remove the CV axle using a socket set, and replace it with a new one. Torque the axle nut to the manufacturer's specifications.

4. Inspect and Replace Suspension Components

Check control arms, bushings, and strut mounts for wear or damage.
If any components are worn, remove them using a socket set and replace with new parts.
Reinstall all components and ensure they are torqued to the manufacturer's specifications.

5. Inspect Wheel Bearings

Spin each wheel to check for any grinding noise or roughness.
If a wheel bearing is suspected to be faulty, remove the wheel and hub assembly.
Replace the bearing using a bearing puller and reinstall the assembly, torquing to specifications.
