1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts during repairs.

2. Tire Inspection and Replacement

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench.
Check tire pressure and inflate to manufacturer's specifications if necessary.
Inspect the tires for signs of uneven wear or damage; if any tires are damaged, replace them.
Reinstall the tires and torque the lug nuts to the specified value (usually 80-100 ft-lbs).

3. Suspension Component Inspection and Replacement

Tools Required: Socket set, pry bar, torque wrench.
Visually inspect all suspension components for wear; replace any damaged parts.
Tighten any loose bolts to the manufacturer's specifications.
If necessary, replace control arms or struts, ensuring to torque all fasteners correctly.

4. Driveshaft and CV Joint Inspection

Tools Required: Socket set, pry bar.
Inspect the driveshaft for any signs of damage or excessive play.
Check CV joints for torn boots or grease leakage; replace if damaged.
Reassemble and ensure all fasteners are secured.
