1. Preparation:
* Safety First: Engage the parking brake firmly. Chock the rear wheels with wheel chocks or large heavy objects (bricks, etc.) to prevent the car from rolling. Work in a well-lit, level area. Wear safety glasses.
* Gather Tools: You'll need a lug wrench (the one that came with your car is ideal), and a jack and jack stands. A wheel chock is also recommended.
2. Jacking Up the Car:
* Locate the Jack Points: Consult your owner's manual for the correct jacking points for your 1998 Monte Carlo. Generally, there are reinforced areas on the frame near the front wheels. Do not jack up the car on the suspension components or the pinch welds (the metal folded edges of the body).
* Position the Jack: Securely place the jack under the designated jack point.
* Raise the Car: Slowly and steadily raise the car until the tire is a few inches off the ground.
3. Secure with Jack Stands:
* This is crucial for safety: Once the tire is off the ground, place jack stands under the frame near the jacking point. Lower the car onto the jack stands. Never work under a car supported only by a jack.
4. Removing the Wheel:
* Loosen Lug Nuts: Use the lug wrench to loosen the lug nuts on the wheel. Turn them counterclockwise. You may need to put your weight on the wrench to break them loose. Don't remove them completely yet, just loosen them enough to turn by hand.
* Remove Lug Nuts: Once loosened, completely remove the lug nuts and keep them together in a safe place (a small container or the hubcap).
* Pull Off the Wheel: Carefully pull the wheel straight off the hub. It may require a bit of force, but avoid jerking or prying.
5. Reassembly (When Replacing):
* Mount the New Tire/Wheel: Align the new tire/wheel onto the wheel studs.
* Tighten Lug Nuts: Hand-tighten the lug nuts.
* Lower the Car: Carefully lower the car from the jack stands using the jack.
* Tighten Lug Nuts (Final): Once the car is on the ground, tighten the lug nuts in a star pattern (opposite nuts first, then the ones in between) to ensure even pressure. Don't overtighten.
6. Final Check:
* Double-check: After tightening, give the lug nuts a final check to ensure they are securely fastened.
* Lower the Jack: Completely lower the jack.
Important Considerations:
* Torque Specifications: Consult your owner's manual for the proper torque specifications for your lug nuts. Over-tightening can damage the wheel studs, while under-tightening can cause the wheel to come loose.
* Flat Tire Repair/Replacement: If you're replacing a flat tire, ensure you have the correct replacement tire with the correct size and pressure.
If you are not comfortable performing this task yourself, it is always best to take your car to a qualified mechanic or tire shop. They have the right tools and expertise to do it safely and efficiently.
