[FC] grinding noise

[Ken Hand]

 Grinding noise is like saying your arm hurts. 

Do you know specifically where the noise is coming from? Of course not! if you did you wouldn't be asking here. 

Is the grinding all the time? Is there a once in a rotation grind? Is it a rumble rather than a grind? Is it under acceleration, deceleration? Is it there when you turn both ways, L & R?

In just using what you said below, Check the brake drum to backing plate. If there was a change in the wheel attitude it could be rubbing and that would sort of go away at higher speeds. If it is the drum to backing plate it will be near the top of the plate.

My wife's Greenbrier has a grinding noise that is correlated with the wheel 
 rotation. It's on the passenger side. I checked the U-joint and it was 
fine, and  drove it myself today, and the grinding noise can be felt as well as 
heard. It  seems to go away at higher speeds. I suspect the wheel bearing, 
as I noted it  had some play when I took the axle off to service the 
U-joint. I also am  noticing that the van is sitting a little lower on that side 

than the other, I  can barely fit my fingers between the tire and the fender. 
I visually inspected  suspension and it appears fine, and I couldn't see any 
place where there is  rubbing as the wheel rotates. It doesn't make the 
grinding unless there is a  load on the wheel, so rotating it while jacked up 
doesn't produce the  sound.
 
Wheel bearing?
