I recently purchased an 06 ford e350 van with a 6.0 diesel engine with 150,000 thousand miles. At approximately 55 mph a humming noise comes from the passenger side of the engine compartment. Slightly letting off the gas eliminates the noise for a few seconds. To travel above 55 I must constantly massage the pedal or keep my speed around 50 to avoid the high pitched humming noise. The local dealership recommends dropping the transmission to have a look. What thinks you?
