Lift the vehicle using a hydraulic lift or jack stands.
Remove the front wheels for easier access to alignment components.
Set the alignment machine according to manufacturer specifications.
Adjust camber, caster, and toe settings as necessary.
Reinstall the front wheels and lower the vehicle.

4. Inspect and Replace Worn Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Inspect the suspension for worn or damaged parts, including bushings and ball joints.
If any components are found defective, replace them with OEM or high-quality aftermarket parts.
Torque all bolts to manufacturer specifications.

5. Tire Rotation

Tools Required: Jack, jack stands, tire iron
Lift the vehicle and remove the wheels.
Rotate the tires according to the recommended rotation pattern (usually front-to-back or side-to-side depending on tread design).
Reinstall wheels and torque lug nuts to specified values.
