Step 3: Reassemble and Torque

Reinstall all components in reverse order.
Ensure that all bolts are torqued to the manufacturer’s specifications (refer to the service manual).
Reinstall the rear wheels.
Lower the vehicle from the jack stands.

Step 4: Alignment Check

Perform a wheel alignment using an alignment tool or take the vehicle to a professional service.
Adjust as necessary to ensure proper alignment.

Final Steps
