Using a socket set, remove the wheels to gain access to the suspension.
Check the control arms, bushings, and struts for signs of damage or wear.
Replace any worn or damaged components with new parts.

4. Check Wheel Bearings and CV Joints

Spin each wheel to check for roughness in the wheel bearings.
Inspect the CV joints for any visible tears in the boots or signs of grease leakage.
Replace any worn bearings or CV joints as necessary.

5. Tighten or Replace Loose Components

Inspect and tighten any loose bolts or nuts on the suspension and drivetrain components.
