- Position a jack under the vehicle’s designated lifting point and raise the wheel off the ground. Make sure to follow proper jack placement guidelines as outlined in your vehicle’s owner’s manual.
- Once the wheel is off the ground, remove the lug nuts and take off the wheel.

- Place the wheel back onto the hub and hand-tighten the lug nuts in a star or crisscross pattern to ensure even tightening.
- Using a torque wrench, tighten the lug nuts to the specified torque value in a star or crisscross pattern. This helps distribute the torque evenly and prevents warping of the brake rotor.
- Double-check each lug nut to ensure they are properly torqued.
- Repeat the process for each wheel on your 2004 Chevy Impala.
- Lower your vehicle using the jack and remove the jack from under the car.
