Sound coming from front end 2013 raptor

morning..........

without knowing or being there in person to hear it, does the noise go away in 4wd? need to narrow down location

I haven’t heard it in 4wd however I’ve never really used it in 4wd at constant rpm’s to cause the sound. It happens around 1500-2000 rpm’s and continues into higher rpm’s till I let off the gas. It doesnt happen when idling or when starting.

Noise varies with engine rpm?
Not drivetrain speed or wheel speed?
If engine, possibly any of the accessories; PS pump (which I have replaced and seems fairly common-any steering issues?), water pump (any leaking?), air conditioning compressor (any issue visible-dust from clutch?)
Good luck finding the culprit and fix.
Enjoy the Raptor !!!
