Drive shaft support bearing. $20.00 for a cheap one. $40.00 for a quality one. If the rubbber donut is still firm and flexible you can reuse it. R&R takes 1 hr if you know what you're doing 3 if you don't. YOu can pull the B with a block of wood and a heavy hammer although a press would be nicer. Garage should not charge more than 1 hr. These Bs whine when they're cold but fail without warning when they are hot, usually at highway speeds and it's not pleasant. Been there, patrick.
