Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if any electrical components will be involved.

2. Check and Top Off Power Steering Fluid

Locate the power steering reservoir and inspect the fluid level.
If low, add the manufacturer's recommended power steering fluid to the appropriate level.
Reconnect the reservoir cap securely.

3. Inspect and Replace CV Joints (if necessary)

Lift the front of the vehicle and secure it on jack stands.
Remove the wheel to access the CV joint.
Inspect the CV boot for tears or grease leakage.
If damaged, remove the axle nut and disconnect the CV joint from the transaxle.
Replace with a new CV joint or axle assembly as required.
Reassemble the wheel and lower the vehicle.

4. Check Wheel Bearings

With the wheel removed, grasp the brake rotor and check for any lateral play.
If play is detected, remove the rotor and hub assembly.
Replace the wheel bearings as needed, ensuring proper installation and lubrication.

5. Inspect and Repair Suspension Components

Visually inspect control arms, bushings, and struts for wear or damage.
Replace any worn components; use new bushings and torque bolts to manufacturer specifications.
Reassemble any disassembled parts and test for noise.
