A bearing nut is a specialized fastener used to secure and adjust the position of bearings in machinery. It typically features an internal thread that allows it to be screwed onto a shaft or housing, providing a tight fit that maintains the alignment of bearing components. Bearing nuts can also include features like locking mechanisms to prevent loosening due to vibration or movement. They are commonly used in various applications, including automotive, aerospace, and industrial machinery.
There is no "middle nut" on a tire. -I can only assume you may mean the 'spindle nut' or 'main wheel bearing nut'. That is what holds your wheel bearing tight to the CV joint. In 94 Taurus it is a 1 and 1/4 nut
The front axle nut would be a 35mm.
When changing a hub bearing, it's essential to replace the axle nut because the original nut is often designed for a single-use application. Reusing the old nut can lead to improper torque, which may result in loosening or failure of the bearing assembly. Additionally, the nut may have worn threads, compromising the integrity of the connection. Installing a new nut ensures a secure and reliable fit, maintaining the overall safety and performance of the vehicle.

I believe it is a 36mm.
After you remove the wheel, remove the caliper and caliper mounting bracket. There is a nut on the end of the axle shaft. Remove the nut. There are three bolts on the back of the steering knuckle that hold on the wheel bearing. Remove these bolts. Then with a punch or chisel and hammer, strike the axle shaft until the old bearing comes out. Reverse procedure to install. Don nut re-use the axle shaft nut. Do not under- or over-tighten the axle shaft nut. Torque for the nut is 180 ft lbs.
