Rear Bearing

I bought the bearing kit# 5303281153. I noticed a ball bearing in the kit. When I took the dryer apart there was extreme damage to the bearing and the plate around it, but there is no ball bearing. Where does the ball bearing go?

Thanks

the ball bearing goes in the hole on the back side of the plastic looking bearing cup.between cup and metal piece screws go through.put a dab of grease on hole to hold ball bearing in place while yo put screws in
