Shoulda,Woulda,Coulda. You'll see by the pics what happened. I did not do the proper maintenance. A couple of weeks ago I put a new tire on the rear and skipped the total maintenance. I would have found this sooner, not that it would have been any better. I do the whole maintenance when I change the tire but when I get 20,000 miles on a tire things are getting over due. Making sure the holes in the pinion cup are clear may have prevented this too. I don't know what happened to the grease I put in there last time but it obviously doesn't last 20,000 miles. Cost isn't as bad as not being able to ride. PLEASE LEARN BY MY MISTAKE!!       |

Funny, I have kept a shaft and cup from three years ago that looks exactly like that. It's a reminder it do ALL the maintenance...

It looks like your seal is all f'd up. Do you think that might have let water get in ? Or do you think the dry pinion f'd up the seal ?

These pics always remind me of Archaeology 101 class.
Sorry for your troubles.

Please tell us what grease you used so we all know what NOT to use.

I don't know how the grease would dry up and even if the seal was bad I don't think water could make it in. Is the seal meant to keep the lube in or water out? Wouldn't putting grease in the cup plug up the holes for the gear oil to come through? I used a 3% moly grease. Not moly paste. I'm slacking off on maintenance. While I check the oil level often I didn't check the mileage on the oil. Usually done at 6500 miles and I caught it at 8200 miles. Time flies when you're having fun!  |

I think the only way for the cup to get like that is gear oil from the rear end not getting up there. Plugged holes or low fluid level.

You say you went 20K before doing this, but what about how many overall miles on the bike itself do you have on it?

People have a lot of differing opinions on how this happens. I don't think twenty thousand miles is the issue. I get twenty thousand miles regularly out of a rear tire.
I believe a failed seal can let water up there and that item has seen some water.
Take my opinion with a grain of salt. I have had a failed driveshaft and pinion gear.

The bike is a 1999 standard with 143,000 miles on it. I used moly grease but seems to me that it would plug the holes from the rear end. Wouldn't it make sense to lube with the same oil as in the pumpkin? The bike is 16 years old and I'm still learning. |

I think the important thing is not to pack in the grease but put it on the teeth of each the shaft and cup. After you have cleaned old stuff out and made sure holes are open. On my standard I went 45k before I knew to check the pinion cup. Luckily the grease was still good. I don't think I'd be comfortable relying on just gear oil. It's not very viscous and I think would be pretty dry after sitting just a day. |

I pull mine apart every time I service the splines. It is always wet with oil. I put it back together with absolutely no maintenance. I'm not saying this is right, just my experience. I have only 38,000 miles.

I don't think the seal makes that much difference. Here's why I say that. One time, I assembled the back end by first plugging the drive shaft into the U-joint, then attaching the final drive, being careful to be sure the aft splines went into the cup. It went back together much easier, however it apparently folded one edge of the seal such that there was about an 1/8-inch gap. I discovered this a year later when I took it back apart. The grease was still there and looked like it always did. Of course, I always find a little final drive oil mixed with the grease whereas some folks don't. No sign of water though and I did quite a bit of riding in the rain.

There may be a combination of events, here. If the boot at the front of the shaft is leaking, and the seal is not complete, would that cause this?
