So I needed to replace my alternator in my 230,000 mile F150 5.4L. Sounds like a simple task but the real challenge was what alternator to replace with. Cant buy new Motorcraft from Ford, only remanufactured available. Tried this remanufactured and made a clicking sound. Tried a new CARQUEST alternator made in Malaysia and made a humming noise at low rpms. 3rd time was charm as installed new Bosch alternator assembled in USA and finally no noise. I can remove and install an alternator in 30 minutes now but wish I had only done this job one time.

Ha. I hate when that happens. It's shocking how many junk aftermarket parts are out there.

and these are the benign ones.... I have seen imported brake rotors with inclusions and slag embedded into the surfaces.
