I have a 1999 Ram 1500 4x4 and it's making a nasty metal grinding noise from I believe the drivers side tire on the front end. I think it's my wheel bearings, but I wanted to double check. I uploaded a video to youtube, the link is down below.
Thanks.

Check your rotors and pads, just go through the brakes and see if anything looks too worn. Could be a rock stuck in there too. Just a thought.

 

Jack the driver's side front wheel up and spin the wheel by hand and see if you can pinpoint the noise. Also, try putting one hand on top of the wheel and the other at the bottom and push/pull the wheel in and out to see if you can feel if the wheel bearing may be loose.

 

I had both sides in the air today and not one noise. I know my passenger side bearing is bad, but it's not coming from that side. The drivers side wheel doesn't move at all either.
