Here's what you should do instead:
1. Safety First: If the wheel is still attached, do not drive the vehicle. A partially attached wheel is extremely dangerous.
2. Assess the Damage: Determine how severely the lug nut is broken. If only a small piece is broken off and the remaining threads seem intact, you *might* be able to carefully remove it with specialized tools (see below). However, this is risky and should only be attempted if you're experienced with this type of repair.
3. Removal (If Possible): If the nut is only partially broken, try these options in this order:
* Penetrating Oil: Apply a generous amount of penetrating oil (like PB Blaster) to the broken lug nut and let it soak for several hours or even overnight. This can help loosen rust and corrosion.
* Lug Nut Extractor: These specialized tools grip the broken lug nut to allow for removal. They come in various sizes and designs. Use caution; excessive force can damage the wheel stud.
* Impact Wrench: If the above methods fail, try using an impact wrench. The high torque can sometimes break free a stubborn lug nut. However, be very careful not to over-tighten or strip the remaining threads.
4. Replacement: Once the broken lug nut is removed, you'll need to replace it with a new one. Ensure you get a lug nut that's the correct size and thread pitch for your Chrysler Town & Country. This information should be stamped on one of the other lug nuts. Auto parts stores can help you find the correct ones.
5. Professional Help: If you can't remove the broken lug nut yourself, or if the wheel stud is damaged, take your vehicle to a qualified mechanic or tire shop. They have the tools and expertise to handle this safely and effectively.
Important Note: Driving on a wheel with a broken lug nut or a damaged stud is incredibly dangerous and could lead to a wheel detaching while driving, resulting in a serious accident. Never compromise safety. If in doubt, get professional help.
