very loud noise from the right rear side of the engine compartment

    Has anyone else ever experienced a very loud whirring noise coming from the right rear side of the engine compartment? it seems to only happen at highway speeds after the engine is warm. Taking it out of gear does not change the noise nor does slowing the RPM's. It doesnt seem to impact performance but obviously it's not a good thing. Anyone know what I have going on?

    My first thought was the heater fan with something in it. Try turning it off and see what happens.
    Just a thought, I'm not familiar with your series of truck.

    Good luck finding it

    Putting your gear box in neutral and the noise persists means you can rule out an engine problem.

    Sounds like a tyre ie, missing some tread or the tread has picked up something or a wheel bearing

    Both these things can be easily inspected by jacking up your front drivers side wheel. Give the wheel a shake and a spin to detect a bearing problem, or check the tread

    Good luck
