Apart from a diaphragm failure, in which case the pump will run quietly but not generate a vacuum, the most likely cause of failure is the front bearing.

GM gives this bearing an encrypted part number, apparently to prevent easy matching, but it is actually a common 17mmx40mmx12mm Metric Ball Bearing easily cross referenced to 6203-2RS (the 2RS indicates two rubber dust seals).

If an exchange pump is required the common number is 641018 which covers 1997-2004 Hummers, and the 6.5 diesel used in 1996-1997 Chevrolet and GMC trucks. Do not use a pump specified for 1998 and later Chevrolet and GMC trucks as a different part number is used for these.
