Front brake pads worn out.

No. It is a deeper sound.Sounds like a slower rotation than wheel

Front of the engine? Idler pulleys or a water pump? Or is it when you turn the steering wheel...

not engine related. Only when moving. At 20 mph it grinds around 1-2 seconds intervals and speeds up when I go faster

Sounds like it is in the driveshaft. Have the u-joints checked.

IT IS NOT A SQUEAK, IT IS A GRIND

You know, it can only be so many things, just take it into a garage to be looked at or get under there and check it out.

i REPLACED THE WHEEL BEARING AND HAVE BEEN UNDER THERE, THOUGHT YOU COULD GIVE ME OTHER IDEAS

Could the rotors on the front be warped? Pickups are good for warped rotors if lugs are tightened in excess of specs. At highway speed, if you apply the brakes you can usually feel the pulsation of a warped rotor.

it is not the rotors, it sounds like a shaft bearing of some type. slow rotation compared to the speed of the wheels rotation, like it is geared down.

So is the transmission shifting properly?

What a shop would do is place the vehicle on a lift, let the engine run in 2WD drive and 4 WD and see if they can locate the problem with the wheels turning off the ground. They could probably locate the problem at idle with no weight on the suspension if drive line related.

My 2018 F150 is doing the same thing, started at about 4000km. Sounds like metal on metal, like when you lose a brake pad. It shakes the whole truck. The dealer doesn't know what it is, keep telling me it must be stones between the caliper and the rim. Ford needs to get to the bottom of this, I know of three other 2018's doing the same thing.

We have a 2016 F150. The dealer service guy says Ford are aware of the issue (shaft bearing). We took it in 3 months ago and they greased it, that lasted around 7 weeks. Brought it back in, did it again. Went today and they are now replacing them (but told us the problem will re-occur until Ford figure this out. In my mind, we have been sold a faulty vehicle. I am not happy with having to go to the service shop every 8 weeks and drive a rental vehicle. I'm in shock that this has been a problem (apparently since 2011). Apparently the answer is for a sealed unit (sorry I am not mechanical) but Ford have not come up with the goods?

Thank you I am having the same noise. It is intermittent and really starts up after making a hard left turn. Is this safe to drive?
