I don't know if you can get the rubber only, but you can get a ball joint kit, and yes, the joint is serviceable. It is even possible to service it without removing the arm, which is just as well seeing that these tend to be very firmly attached.
The kit should be about 10-15% of the cost of the arm, and even though servicing it in situ is pretty fiddly, it beats trying to remove the arm.
