I'm pretty sure the bearings have to be pressed off. Are you also aware that most BMW dealerships do not stock the shims, if you need any? Could delay the install a few days as well. Those are the only concers I have on doing mine when the time comes. I know several have not needed shims. You just never know until you get into it.
