Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Steering Components

Tools Required: Socket set, torque wrench, jack and jack stands.
Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to access the steering components.
3. Check the tie rods and ball joints for any signs of wear; replace if necessary.
4. Reinstall the wheels and lower the vehicle; torque the lug nuts to the manufacturer’s specifications.

3. Inspect and Replace CV Joints

Tools Required: CV joint puller, grease, socket set.
Sub-steps:
1. Remove the wheel and hub assembly to access the CV joint.
2. Inspect the CV joint boot for tears; if damaged, replace the entire CV axle.
3. If the joint is intact, clean and re-grease it before reinstalling.
4. Reassemble the hub and wheel, ensuring everything is torqued to specifications.

4. Inspect and Replace Suspension Components

Tools Required: Spring compressor (if replacing struts), socket set.
Sub-steps:
1. Inspect struts and shocks for leaks or damage.
2. Replace any worn or damaged components using a spring compressor to safely remove the strut assembly if necessary.
3. Reinstall the strut assembly and torque all bolts to the manufacturer’s specifications.
