Solution

1. Preparation

Gather tools and parts for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Inspection and Replacement of Suspension Components

Lift the Vehicle
- Use a hydraulic jack to lift the front of the vehicle and secure it with jack stands.
Inspect Suspension Components
- Check the struts for leaks and damage.
- Examine control arms and bushings for wear and tear.
- Look for any cracks or breaks in the components.
Replace Damaged Components
- If any components are found to be damaged, remove the fasteners using a socket set.
- Replace with new parts, ensuring to torque the fasteners to manufacturer specifications.
- Recommended torque values generally range from 40-80 ft-lbs depending on the component.

3. CV Joint and Axle Inspection

Remove Wheel
- Use a lug wrench to remove the wheel for better access to the CV joint.
Inspect CV Joint and Axles
- Look for torn boots or damaged joints. If the boot is torn, replace it along with the joint.
- If necessary, remove the axle by unfastening it from the hub and differential.
Reassemble
- If a CV joint was replaced, reassemble in reverse order and ensure proper torque specifications.
