I have just bought 4 575 spots, is there a limit to the amount of movement on the yoke bearing ie not in the rotation direction of the bearing as there seems to be exessive wear on it, only one unit is affected.
If the unit was dropped at one time it could of damaged the bearing in a spot. They are sealed so lube is not an issue. Replace the bearing. Careful! It isn't a walk in the park as I remember.;) Make sure some of the hub screws have not backed out, they can drop and ruin your day.
