I have a 2000 Ford F-150 supercab., 5.4 V8, 4X4 Flairside Lariat.

A few weeks ago I started hearing what sounded like a washer bouncing around on a loose bolt from the front left wheel. I checked the bolts & I did not find any loose. I have noticed that the sound is constant as I I drive down the road not just when I hit a bump. So now I am thinking maybe its a wheel bearing or something else. It almost sounds like a chain rattling but its very faint.
Any idea's?
Thanks in advance!

 

I had a similar sound and I thought it was coming from the front as well. It ended up being loose clamps on my rear leaf springs. As soon as those were fastened back down I have nearly no noise from my suspension anymore. So check your leaf spring clamps. If it's not that I'm not sure.
