Well, there are the needle bearings in the case itself, you can get those from the vendors. Then there are the high speed bearings in the snout, then there is the coupler in the snout. In fact if you work at a dealership you should be able to get those yourself, if not then they can be purchased from one of the vendors. Just make sure the bearings, particularly those in the snout are high speed bearings.
A common issue with the blowers is that the coupler will go bad and it will sound like little rocks tumbling around in the blower.
