I had a problem with my fuel injector on a 2006 F-150. It went bad, leaked fuel into my oil lines, etc. Changed fuel injector, spark plugs, oil…blah blah blah. Now, whenever I speed up or slow down (not brake, just let my foot off accelerator) my truck makes a horrible sound like a turbine spinning slower and slower as I slow down. It seems to happen when I speed up or slow down - but not based on brake or accelerator pedal. No vibrations at all, the sound is just really bad like you would hear when a turbine engine or prop spins down. Could something be wrong with an axle or bearing in a wheel? My dealer said they could not hear a sound and there was no problem. however, other people who ride in my truck comment on the bad sound. Any Help? ---

I can’t give you an answer to your noise problem but I am wondering why everyone who rides with you can hear the noise but the dealer can’t. Did a tech ride with you on a test drive? I don’t care to say this often but perhaps this dealership is trying to duck a (possible) warranty job. Normally new vehicle factory warranties cover all drivetrain faults don’t they? If so, the manufacturer pays. Isn’t the engine part of the drivetrain? I hope you get this fixed before the warranty runs out. Maybe that’s what the dealer is trying NOT to do. ---

If it is not connected to engine RPM or breaking, I would guess maybe a wheel bearing. Can you tell where the sound is coming from, front back right or left? My other thought is possibly the transmission, maybe. Is it standard or auto? A sound like that probably wouldn’t be related to fuel or ignition components. ---

I had this happen to a '92 Buick Lesabre I had. I thought it sounded cool, especially since I couldn’t find any problem. However, this was the start of the water pump bearing failure which eventually appeared as coolant on my driveway. ---

It sounds as if the noise is coming directly from under me, possibly just in front of the driver. It as an automatic transmission. I didn’t think the sound was related to the fule injectors either, but I only noticed the noise after the repairs were done. I am thinking now the noise is related to the spinning of the tires. At high speeds the noise is not noticeable - though it may be masked by the engine. At slower speeds when I am coasting is when you hear it the most. ---

You didn’t mention it but do you have a turbocharger on your engine? ---

No, I do not have a turbocharger on the engine. ---

Since the plugs were changed, they should be checked for looseness. I had one come loose on a 65 289 in a Fairlane but it made a knocking sound. In addition to the water pump that was mentioned, I can only suggest that something may be rubbing on a moving part or a serpentine belt is starting to come apart and the threads are hitting on something. Sure sounds like something.
