Tools you'll need:
* Lug wrench: The correct size for your Lumina's lug nuts.
* Jack: A floor jack is recommended for safety. Never work under a car supported only by a jack. Use jack stands for added security.
* Jack stands: Essential for safety. Place them securely under the frame near the jacking point.
* Wheel chocks: To prevent the car from rolling.
* Socket wrench (optional but recommended): A ratchet with the correct socket size can make the job easier than a lug wrench.
* New lug bolt: Ensure you get the correct size and thread pitch for your Lumina. Your owner's manual or a parts store can help determine this.
* Gloves (optional): Protect your hands.
Steps:
1. Safety First: Park on a level surface, engage the parking brake firmly, and use wheel chocks on the wheels opposite the one you're working on.
2. Jacking the Car: Consult your owner's manual for the proper jacking points. Never jack up the car on the rocker panel or bumper. Use the designated frame points. Carefully raise the car until the tire is a few inches off the ground.
3. Secure with Jack Stands: Place jack stands under the frame near the jacking point, ensuring they are stable and secure *before* removing the jack. Never work under a car supported only by a jack.
4. Remove the Wheel: Use your lug wrench (or socket wrench) to loosen the lug nuts. Turn them counterclockwise. They'll likely be tight, so you might need to put your weight into it. Don't completely remove them yet; just break them loose.
5. Remove the Lug Nuts: Once loosened, completely remove the lug nuts and keep them in a safe place.
6. Remove the Wheel: Carefully pull the wheel straight off the hub. It might be a little stubborn.
7. Replace the Lug Bolt: Identify the damaged or missing lug bolt. Carefully insert the new lug bolt into the wheel hub, ensuring it threads correctly.
8. Reinstall the Wheel: Carefully line up the wheel with the wheel studs and push it onto the hub.
9. Tighten the Lug Nuts: Start by hand-tightening all the lug nuts. Then, using your lug wrench (or socket wrench), tighten them in a star pattern (opposite nuts, then the ones in between). This ensures even pressure distribution. Don't overtighten yet.
10. Lower the Car: Carefully lower the car using the jack, keeping an eye on the wheel to ensure it remains properly seated.
11. Final Tightening: Once the car is on the ground, use your lug wrench to tighten the lug nuts firmly according to the manufacturer's specifications (usually found in your owner's manual). Don't overtighten; this can damage the wheel studs or nuts.
12. Torque Wrench (Highly Recommended): For optimal safety and to avoid damage, use a torque wrench to tighten the lug nuts to the manufacturer's specified torque. This information is often found in your owner's manual.
Important Considerations:
* Thread Pitch: Make absolutely sure the new lug bolt has the correct thread pitch (the distance between threads). Using the wrong bolt can damage the wheel hub.
* Wheel Stud Damage: Inspect the wheel studs for any damage while the wheel is off. Bent or damaged studs should be replaced.
* Lug Nut Condition: Inspect the lug nuts. If they are damaged, corroded, or show signs of wear, replace them.
Again, if you're unsure about any of these steps, seek professional help. Improperly installed wheels can be extremely dangerous.
