Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect the struts, shocks, and control arms for any signs of damage or wear.
3. Check for loose bolts and retighten them to the manufacturer's specified torque (typically 15-20 ft-lbs for suspension components).

Tools Required:

Jack and jack stands
Socket set
Torque wrench

3. Examine CV Joints and Axles

Sub-steps:
1. Inspect the CV boots for tears or leaks of grease.
2. Rotate the wheels while observing the CV joints for any abnormal movement or noise.
3. If any damage is found, replace the CV joint or axle as necessary.

4. Tire Inspection
