I was checking out my front end today and noticed something that concerns me.  The truck is an '02 4X4 crew cab.  I had the front end off the ground, and noticed that one wheel spun freely, and the other had a lot more resistance when spun, like it was dragging.  I took the hub off, and everything seemed well greased, and the calipers didn't seem to be catching.  Any thoughts on what this could be? Also what is the difference between exausts for the super charged and nonsc engines?  I find lots of cat back systems for the normal engine, but not the sc engine.  Is there a difference?

Thanks
