Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Use safety glasses and gloves during the inspection and repair process.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the strut assembly, including the strut mounts and bushings for signs of wear.
4. Replace any damaged components (e.g., strut mounts, bushings) with OEM parts.
5. Reinstall the wheels and lower the vehicle.

3. Inspect and Replace Drivetrain Components

Sub-steps:
1. Check the CV joints for tears or damage.
2. If damaged, remove the axle by disconnecting the lower control arm and hub assembly.
3. Replace the CV axle with a new one, ensuring it fits properly and is secured.
4. Reassemble all components and ensure all fasteners are torqued to specification, typically around 60-80 ft-lbs for wheel lug nuts.

4. Tire Inspection and Rotation

Sub-steps:
1. Inspect all tires for uneven wear or damage.
2. Rotate the tires if uneven wear is detected or replace if necessary.
3. Ensure proper tire inflation is maintained as per manufacturer specifications.
