Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Inspect and Replace CV Joint (if necessary)

Tools Required: Socket set, pry bar, torque wrench, CV joint replacement kit.
Remove the wheel by loosening the lug nuts and using a jack to lift the vehicle.
Sub-steps:
1. Remove the axle nut using a socket.
2. Detach the lower control arm from the steering knuckle using a pry bar for leverage.
3. Slide the CV joint out of the transmission or differential.
4. Inspect the old CV joint for wear and replace it with a new joint, ensuring it's properly seated.

3. Inspect and Replace Wheel Bearings (if necessary)

Tools Required: Bearing puller, socket set, torque wrench.
Sub-steps:
1. Remove the wheel and brake caliper for access to the hub.
2. Detach the hub assembly from the suspension.
3. Use a bearing puller to remove the old bearing and replace it with a new one.
4. Reassemble the hub and torque all components to the specified values.

4. Check Suspension Components

Tools Required: Wrench set, torque wrench.
Sub-steps:
1. Inspect the struts and shocks for leaks or damage and replace if necessary.
2. Tighten any loose bolts or nuts on the suspension components.
3. Perform a visual inspection of bushings and replace any that are worn or cracked.
