3. Inspect Steering and Suspension Components

Visually inspect the tie rods, control arms, and sway bar links for any signs of damage or excessive wear.
Use a socket set to tighten any loose bolts or nuts found during the inspection to the manufacturer's torque specifications.

4. Examine Wheel Bearings and CV Joints

Remove the wheel using a tire iron and socket set.
Check the wheel bearings for play by moving the wheel side to side; replace if excessive movement is detected.
Inspect the CV joints for any cracks or torn boots; replace if damaged.
