why would you want to replace a part that is working? you could stick a voltmeter across the battery .. at idle it should read at least 13.8 volts.
when my original alternator started making noise (bearings were almost shot), i replaced it with one that was 3 years old that i got at a pick n pull.. for $25.-...
if yours is still putting out good voltage and not making noise leave it be.
