That sounds more like bearings.

 

Ok, I just jacked up my truck and rotated the wheel, and I heard a rattling noise rite behind the wheel. Looks like I am replacing a bearing this weekend! I have a friend that works at a Ford dealership that might be able to get me a good price on a wheel bearing & hub assembly. I am expecting $100-200? That sound about rite for a good bearing?
Thanks again for all the help everyone!

 

I paid $75/ea for my 2WD rotors. I just swapped and greased the bearings over from the older one.

 

To give you an idea, at rockauto.com the prices run from $70 to $225, depending on brand and whether it has front ABS or not. Looks like quality brands such as Timken or Moog/National are in the $150 range.
