Synchronizer Shaft for camshaft position sensor upper bushing goes bad and makes squealing sound like a loose belt (replace)
had the same problem friend works at ford, found, and fixed the issue quickly...part is expensive trough ford...aftermarket part is 1/4 of the price.
Had the intermittent squeaks. Mechanic diagnosed it immediately. Replaced synchronizer and sensor. No more squeak, but 'Check Engine Light' is not always ON
something in the engin "churps" when the engin is warm
chirps when the engine is warm.
chirping sound at random times with the engine running.
Severe squeaking both front tires area.
Lous chirpibg under cab when clutch released
troubleshooting a loud constatnt annoyng sqieal like a belt but suspecting compressor for a/c...thinking it might be the cam shaft postion senor shaft bushing failure
Loud chirping/squeak when engine is warm, erratic. CPS or synchronizer.
