Tools Required: Jack stands, socket set, grease.
Safely lift the vehicle and remove the wheel to access the CV joint.
Inspect the CV boot for tears or leaks. If damaged, replace the entire CV joint or axle.
Reassemble the wheel and lower the vehicle.

4. Inspect and Replace Suspension Components

Tools Required: Wrench set, socket set, torque wrench.
Use a jack to lift the vehicle and support it securely.
Visually inspect struts, shocks, and control arms for wear or damage.
Replace any damaged components and ensure all bolts are torqued to specifications.

5. Tire Inspection and Alignment

Tools Required: Tire pressure gauge, alignment tool (if available).
Check tire pressures and adjust to manufacturer specifications.
Inspect tires for uneven wear; replace if necessary.
If required, perform a wheel alignment to ensure proper handling and tire wear.
