E36 328 Alternator

[mike3]

hi,heard the alternator was noisy this evening, with engine on idle and aircon "off". Thought it was quite loud, like some "bearing" going off.pls advise if the alternator (NipponDenso) can be serviced (change bearings etc..) or must i have to get a new or "recond" unit?tks for reading, and advise appreciated.Also, appears that the previous problem with the jumpy fuel gause solved by changing two wires at the RHS fuelpump/gauge assembly.mike
