re: Paging F150 Mechanics - Update in Original post.

Thanks for the Replies, I'm going to take it in this afternoon anyway. Had to have the wiring harness for the alternator and electronic assisted power steering replaced a couple of weeks ago. (it came loose and rubbed a hole in the insulation) They also found an oil leak but couldn't locate it so they added dye to my oil to try and locate it. I'll have them check the drive train over and see if they can find it.

I've had wheel bearing issues before and really don't think that's it. The sound is not constant like a wheel bearing would be. I'm really hoping this is not the beginning of constant issues with this truck. I'm supposed to be driving this thing to NM in about 4 weeks. Would like to get all this taken care of beforehand.
