What is your question?
we have a noise that sounds like the clicking from a belt problem. the mechanic replaced the serpentine and tensioner but did not stop the problem. He now says it is a pump bearing and has charged another $350 to replace. What is a pump bearing and is this an honest price?

There are several items that rotate in conjunction with the serpentine belt. Any one of which can cause a noise when turning. Sometimes it can be quite difficult to pinpoint the cause of the noise. Some items which the serpentine belt can turn include: idler pulley(s), alternator, a/c compressor, power steering pump, and water pump. If a "pump bearing" has now been diagnosed as the cause of your noise I would suspect it is the power steering or water pump. I am sorry I cannot give you an estimate with out knowing which part has failed. However $350 does not sound to far out of range for either part. Before proceeding with this latest repair you may want to try and find out how sure you mechanic is that this latest repair will take care of you noise problem.
