Ever have any issues with this pto driveshaft? Universal joint seems fine, hard to check as it has a rubber sleeve over the universal. The front mount in the bearing and bracket keeps it still and in place, but the back end just sits on the output pto shaft. Theres alot of wobble up and down on it. When its spinning free, theres wobble but under load it tightens up. Anyone drill the back one and add set screws to keep it still?
