The Xtreme Nights

It all started with my odometer getting stucked and not moving. I took apart the meter console and managed to get the odometer fixed DIY. Now my prob is that the speedometer needle no longer moves smoothly. I believe I did not re-install it back properly. I am stumped because the speedometer needle assembly has got a very small ball bearing (just one) and I am not sure where to put this. My needle would move up with increase in speed but once I am slowing down, the needle does not move...
