Solution

1. Preparation

Gather the necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.

2. Inspect and Replace CV Joints

Tools Required: Socket set, torque wrench, pry bar, CV joint puller (if necessary)
Sub-steps:
1. Remove the wheel on the side where the noise is occurring using the socket set.
2. Inspect the CV boot for any tears or signs of grease leakage.
3. If the CV joint is damaged, use a CV joint puller to remove it from the axle.
4. Replace the CV joint with a new one, ensuring it is properly lubricated with the correct CV grease.
5. Reinstall the wheel and torque the lug nuts to the manufacturer specifications.

3. Replace Worn Suspension Components

Tools Required: Wrench set, torque wrench, ball joint separator
Sub-steps:
1. Identify any worn components during the visual inspection; this may include control arms, bushings, or ball joints.
2. Remove the affected part using the appropriate tools (e.g., ball joint separator for ball joints).
3. Install the new suspension component, ensuring all bolts are tightened to the manufacturer’s torque specifications.
4. Reinstall any removed components and ensure everything is secure.

4. Align the Suspension

Tools Required: Alignment tools or take to a professional alignment shop.
Sub-steps:
1. After all replacements, check the wheel alignment using an alignment tool or take the vehicle to a professional for alignment.
2. Adjust the alignment to manufacturer specifications to ensure proper handling and tire wear.
