Noise From Synchronizer Shaft Upper Bushing on Ford Mustang

The synchronizer shaft for the camshaft position sensor can cause a loud squeak or chirping noise due to failure of the upper bushing. The noise may be erratic and is usually present when the engine is warm.

There was a loud chirping noise when the car is cold. I changed the water pump, idler pulley, belt and the sound still continued. I suspected the camshaft synchronzier and when I took it to a local mechanice he confirmed the issue. The part was changed and the sound immediately went away.It was difficult to pinpoint on my own because the sound would lessen dramatically once the car became warmer.
