1. Check tire pressure using a tire gauge; inflate to manufacturer specifications if necessary.
2. Inspect tires for uneven wear patterns; consider rotating or replacing tires if necessary.
Tools Required: Tire pressure gauge, jack, jack stands.

3. Suspension Component Inspection

Sub-steps:
1. Visually inspect suspension components (control arms, bushings) for signs of wear or damage.
2. If any components are damaged, replace them with OEM or equivalent parts.
Tools Required: Socket set, wrench set.

4. Drive Shaft and CV Joint Check

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Inspect the driveshaft for any visible damage or excessive play.
3. Check CV joints for torn boots or grease leakage; replace if damaged.
Tools Required: Torque wrench, socket set.
