Groaning in front end

Hello,

Groaning front end. Not suspension, pitch changes as RPM changes. Thinking water pump bearings. Cools fine (today).

Takes a while to surface, once heated up and the thermostat is open for a while. Can hear it off of the starts (stop sign). Then sort of masks away by engine noise as RPM/speed increase.

Any ideas?:banghead:

Found it.

Alternator bearings were going. 3 bolts - replaced alt. Good now.
