Wear safety gloves and goggles.

2. Tire Inspection and Replacement (if necessary)

Inspect Tires: Check for bulges, cuts, or uneven wear.
Pressure Check: Inflate tires to manufacturer specifications.
Replacement: If tires are damaged or excessively worn, replace with new tires.

3. Suspension Component Inspection and Replacement (if necessary)

Visual Inspection: Check struts, shocks, and control arms for wear.
Replacement: If any components are found defective, replace them with OEM parts.
Torque Specifications: Follow manufacturer torque specs for reinstallation.

4. Wheel Balancing and Alignment

Balancing: Take the vehicle to a tire shop to have the wheels balanced.
Alignment: Perform a wheel alignment to ensure proper tracking and handling.

5. Drivetrain Inspection and Repair

Driveshaft Inspection: Check for bent or broken driveshafts and replace if necessary.
