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
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
