wheel hub

Put the rotor back on and use the brakes or stick a screwdriver in one of the cooling slots.

Be aware you have a pressed-in bearing that WILL be destroyed if you remove the hub from the spindle. Most other manufacturers stopped using this design in the early '90s. You will also make the bearing noisy if you put the vehicle's weight on it without having the axle nut torqued to specs. The proper setting is very high and is critical.

You should not have to remove the hub to replace a wheel stud. Look for a spot where you can sneak the new stud in. Older Chryslers had a place marked that you could knock out to make a space just big enough for the job. Your car probably has something like that too.

For this model and all Honda or Acura models you have to separate the hub or at least pull it out slightly.

For releasing the hub nut, reinstall the tire and lower vehicle. Loosen with the tires on ground.

A loose axle nut with the vehicle weight on the bearing will make it noisy.

No, it would not because the bearing has to be loosened and impacted before it would go bad.
