I agree with bimmerfan52's logic in going with new alternator given that it's not super expensive. Even if the remanufactured/rebuilt one comes with warranty, you will have to remove it and take it back. On N52 engine, it's not bad; however, it looks like it's a lot of work on a 545. If you are DIY guy and understand the both pro/cons of having the alternator rebuilt, then go ahead and have the bearings [and brushes, if necessary] replaced. Otherwise, buy a new one and have peace of mind.
