Take the shield off and examine it. You cannot leave it out as it also acts as a sprocket spacer. If you leave it out the sprocket cannot be fasten securely with the clip. It will have some play, eventually destroying the sprocket driver notches.
I would take the hub apart, at least as far as removing the inner assembly from the shell and see if it is severely gunked up. You need to verify if anything is damaged/worn beyond repair.
