eek! funny noise
2012 F150, 5.0
Quiet at idle, makes a crinkly, scratching noise under load, becomes almost a rattle or sounds like something is dragging (there isn't anything dragging). I can rev the engine in P and do not get the noise, only when in gear and moving. Quiet when cruising, noise comes on when accelerating. Did not notice the last time I drove it, it sat for a couple of days, then noticed it the next time I drove (yesterday). Took it around the block this morning to see if it was still making the noise, it is.
Obviously, it needs to go to the dealer, but want some idea if it's harmful to drive it there, or if I should have it towed.

As a matter of fact ...
"Customer states she hears a grinding noise when accelerating*. Found wheel hubs grinding at times. Needs new IWE actuators installed. Replaced IWEs. Found root cause to be chewing on vacuum lines causing IWEs to be ground."
*in fact, the customer stated a lot more than that, including the suggestions above. I understand the need for them to do their own diagnosis, but I did give them a pretty big hint. The vacuum hose thing just fit too well not to share with them, including the noise abating when in 4wd. They did not charge extra for replacing the vacuum lines
