I hope someone can help with this. I think that I have a bad wheel bearing but I'm not sure if thats what it is. The noise (in the video) only happens when I'm rolling. Doesn't matter if I'm in gear or just coasting in neutral, also it doesn't happen while stopped and idling. I can only hear the noise coming from my passenger side and it sounds like its coming from the front wheel but I'm not 100% sure of that because I had thought I heard it more from the rear the other day. It is now a constant sound that I can hear while driving. The video I have attached is just coasting at about 30-35mph down a hill with a guard rail on the side of the road. Also, it is on a 93 ext cab if it matters.

Thanks for any help.

 

doesn't sound like bearing to me.Sounds like something is hitting that shield that is behind the rotor.Something with thin metal sounds like.

I don't know I just listened again.Maybe its the recording.Jack her up and see if you can make the noise by hand.
