Solution

1. Preparation

Tools Required: Jack, jack stands, wrench set, torque wrench, pry bar
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks.

2. Inspect and Replace CV Joints

Lift the vehicle: Use a jack to raise the front of the vehicle and secure it with jack stands.
Remove the wheel: Use a wrench to loosen the lug nuts and remove the front wheel.
Examine the CV joint: Inspect the CV joint for any visible damage or torn boots. If damaged, proceed to replace.
Remove the CV axle: Unbolt the axle nut and separate the axle from the hub. Use a pry bar if necessary.
Install new CV joint: Insert the new CV joint into the hub and secure it with the axle nut, tightening to manufacturer specifications (usually 30-50 ft-lbs).
Reinstall the wheel: Place the wheel back on and torque the lug nuts to specification (usually 80-100 ft-lbs).

3. Check and Replace Wheel Bearings

Inspect wheel bearings: Spin the wheel hub and listen for any grinding noises or excessive play.
Remove the hub assembly: If worn, unbolt and remove the hub assembly from the knuckle.
Install new bearings: Press new bearings into the hub assembly and reinstall it, ensuring proper alignment.
Torque bolts: Tighten the hub assembly bolts to the recommended specifications.

4. Inspect Suspension Components

Check control arms and bushings: Look for any signs of wear or damage; replace if necessary.
Replace worn components: If bushings or control arms are damaged, unbolt them and install new parts, tightening to specifications.
