Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks. Use jack stands to support the vehicle after lifting.

2. Inspect and Replace Power Steering Fluid

Check the power steering fluid reservoir.
If the fluid is low, add the manufacturer-recommended fluid type.
If the fluid appears dirty or contaminated, perform a fluid flush.

Slide the CV axle out and replace with a new CV joint assembly.
Reinstall the axle, torque the axle nut to the manufacturer's specifications.

4. Replace Wheel Bearings (if necessary)

Remove the wheel hub assembly from the vehicle.
Use a bearing puller to extract the old wheel bearing.
Install the new wheel bearing using an appropriate tool to avoid damage.
Reassemble the hub and wheel, ensuring all bolts are torqued properly.

5. Inspect and Replace Suspension Components (if necessary)

Check control arms and bushings for any signs of cracking or wear.
Replace any damaged bushings with new ones, using a press to install them.
Reassemble and torque all suspension components to specifications.
