That noise is coming from the solenoid, not the starter. The solenoid is making a noise because of low voltage. That is likely caused by:
1. A weak battery (charge it & check it per tip # 49))
2. Dirty grounds/connections (remove the cables & clean the connections)
3. Bad cables or incorrect sized cables (replace them - see tip # 41)
4. Bad ground between the starter & the block. (pull the starter away from the block & clean the mating area - see tip # 36)
If you are confident that you have attended to these likely causes, then jump the solenoid. See tip # 43 before you do that.
