I have seached the forum but don't see the same noise I hear.

I have a 2012 f250 4x4 with the 6.2. About a month ago, I began noticing a noise that sounded like a tire noise like one of the fronts was cupped up. Noise is between 5 and 35 mph and doesn't seem to change with swerving right and left. Rotated the tires and it was less noticeable but noise was still there. After rotating the tires, I was unable to pinpoint noise from front or back.

I picked up some king ranch wheels and tires, not for the noise but just because.

Noise is still there. But seems to be coming from the front.

Has anyone heard a bearing making this noise? In the past when I had a wheel bearing fail, it was typically a growling sound.

 

My 12 F250 is making a "whirring" noise in the front end. I noticed it first during our last cold weather event but now its warmed up a bit and the noise is still there. When it was very cold my 4 wheel drive wouldn't engage unless I locked the hubs. It works again now that its warmer. Don't know if that has any pertinence to anything? Its a company truck with about 150k miles.

 

Try it with the hubs locked and unlocked, along with 4wd and 2wd just to see if any of those makes a difference.

There are grease zerks on both front wheels; I'd make sure those are greased up (probably not the cause though)

 

Yesterday I jacked up each front wheel and gave them a spin. Passenger side was quiet, driver side sounded like the brake was dragging but had no resistance. Pulld tire, brake caliper and pads. Same noise. I verified that there wasnt any rocks or other debris stuck in the dust shield.

I found the noise. Ordered a replacement from Rockauto.

I didn't do this before because I thought it needed the weight of the truck to make the noise.

 

I tried this, noise was the same with them locked and in 4wd. Thanks for the suggestion.

 

The front drivers side brake line is always the first to delaminate, the result produces a "whirling howl" as the caliper drags. Replace this brake line for certain, consider replacing the others due to age, might as well add SpeedBleeders on the calipers and chase out the old fluid with fresh
