Seems like a occilating light grinding noise from the front end. Nothing noted during PA inspection. Seem to recall a similar noise but much louder when my iwe actuator went bad on my 2011 . Similar to a warped disc grinding on brake pad

Anything else I might look at2017 super crew 5.0 4a/4h
38k miles

 

You might consider adding more truck details to your signature. If you have 4wd, and the 4A option on the dial, run the truck there and see if you still hear the grinding.

 

Still hear it in 4a

 

If it's most noticeable around 30-40 mph, it might be your outer wheel hub. I wasn't getting any oscillating issues, but was getting a grinding noise.

 

That implies that it is not the IWE and possibly a wheel hub. Does it do it more driving straight, or with a left or right turn at speed?

 

I'll check....it's pretty faint with windows up. Really only notice it when at idle like coasting up to a stop or when slow enough wind noise doesn't mask it
