I have a bad inner seal and it has started to leak quite severely. The entire inner part of the wheel is coated in oil/grease. The bearings appear to still be good as there is no "play" in the tire. If I am going to change the inner seal, are there any other parts I need to replace while in there? I have heard the outer cap is a one time use and should be replaced as well but I am not sure. Obviously I will need the grease fitting, and oil to refill it, but is there anything else I may need? Just hoping one of you have some experience with this system?

I too am in the same shape with one hub. Thanks GeoFisher for posting this. I've ordered outer seals for my brand of hub, looks like i will have to take the hub off to replace the one on the backside. Any advice will be greatly appreciated here as well.

Here is all I could find Worm. I have the seals, the hybrid oil, the 1/8 inch grease fitting, and the loctite for the caps. I emailed "UFP", the makers of the hub and they said I should have all I need. I am gonna give it a shot later today.
