Zach, from Money Pit, removes the stock steering wheel from his Miata due to discomfort and limited legroom. He explains the process of removing the steering wheel, including disconnecting the airbag and battery, and marking the steering shaft for proper alignment. Zach also discusses the importance of considering factors such as steering wheel size, material, and offset when choosing a replacement. He borrows a friend's steering wheel to test the fit and feel before purchasing a new one. The video also covers the installation of the new steering wheel, including the use of a hub adapter and the importance of proper alignment. Throughout the process, Zach emphasizes the importance of safety, particularly when dealing with airbags.
Here are the key facts extracted from the text:
1. Steering wheels have been used for over 1000 years.
2. In the US, airbags in steering wheels became mandatory as of 1998.
3. Airbags are designed to react within 10 milliseconds and fully inflate within 60-80 milliseconds after an impact.
4. Removing the airbag from a steering wheel can be done, but it requires taking safety precautions into consideration.
5. Adding multi-point seatbelt harnesses can help make up for the lack of an airbag, but it requires installing a roll cage or roll bar.
6. The factory size of the Miata steering wheel is 365 millimeters in diameter.
7. Aftermarket steering wheels come in various sizes, ranging from 280 to 380 millimeters in diameter.
8. Choosing the right size of steering wheel depends on personal preference, driving style, and the type of vehicle.
9. A smaller steering wheel can make the vehicle more responsive, but it may require more effort to turn.
10. The Momo pattern is a common bolt pattern for aftermarket steering wheels, with a 70 millimeter circle and six bolts.
11. The height of the steering wheel hub affects the depth of the steering wheel.
12. The offset of the steering wheel also affects the overall steering setup depth.
13. Soldering is a useful skill for working with electronics, and it can be done with basic tools and materials.
14. A resistor can be used to trick the airbag light into thinking an airbag is present when it's not.
15. The Works Bell hub is a common aftermarket steering wheel hub that connects to the factory steering shaft.
16. The hub has a specific bolt pattern and spline count that must match the steering shaft.
17. The length of the hub affects the overall steering setup depth.
18. A quick disconnect can be added to the steering wheel to increase the depth.
19. The steering wheel can be installed by attaching it to the hub with screws.
20. Torquing the hub to the correct specification is important for safe and proper installation.
