Post Mud buddy long tail seal/shaft question
Hi, I have a lower seal that is leaking ( grease coming out between the seal cap and prop nut). I’m assuming I need a new lower seal set, but I also notice that the shaft itself has a little play in it where it will move in and out about 1/16 of an inch when the drive is turning while engine is running. It doesn’t have any side to side movement that I can see when prop is spinning. Would that indicate a bent shaft still? And if I put a new seal set in would I just be wasting my time without replacing the shaft?
Any input appreciated. Thanks, Matt

When you do the seal, definitely do the bearings, but whether or not you do the shaft or u joints is up to you.

I appreciate it. Do you have any tips to get the lower bearing out of the bearing housing, do I need to take the whole housing off then use a two jaw puller to get the bearing out? Or can I get the bearing off the shaft with leaving the housing on. Thanks
