Unusual Sound
6.0L Forum - I need your help.
I've noticed an unusual sound on my truck. Upon driving if I make a turn more than 15 degrees a "rubbing" sound can be heard through the turn, no "knocking" is not present. Once the steering wheel is straight the sound changes to a "whir". If I turn less than 15 degrees a noticeable sound can not be heard. As the RPM's vary, the sound will also vary. If I get out of the truck and listen for this sound in the engine bay I can not hear it. The sound is only distinct within the cab. It sounds like a weak motor trying to move something or a pump running low, my guess in the dark.
I've checked the oil level - good
I've checked the transmission fluid level - good
I've checked the power steering fluid level - good
I've checked the brake fluid - good
I have read that a master cylinder could wear and create a rubbing/unusual sound. What else should I check for? The truck has 238,000 miles.
Thanks in advance.

No, took the truck out for a drive last night. Did not notice pulling when releasing the steering wheel or applying the brakes.
Yes, the sound can be duplicated when the truck is not moving.

Can you duplicate the sound without moving?

No, I have not recently flushed the power steering fluid. Can you walk me through this thought? Why would the current power steering fluid cause the noise?
The steering does seem a little sloppy, not very smooth.

I have ESOF that doesn't work and have to manually lock the hubs for 4WD.
