1. Remove the wheels using a socket set (ensure vehicle is lifted safely using jack stands).
2. Inspect tires for bulges, punctures, or uneven wear.
3. Replace tires if damaged or excessively worn (balance and align new tires).

3. Examine and Replace Suspension Components (if necessary)

Sub-steps:
1. Visually inspect control arms, bushings, and struts for wear.
2. Use a torque wrench to check bolts and bushings are securely fastened.
3. Replace any damaged components with OEM or high-quality aftermarket parts.
4. Reassemble the suspension and ensure all components are torqued to manufacturer specifications.

4. Inspect and Repair Drivetrain Components (if necessary)

Sub-steps:
