Leaking Rear Diff

[Shank]

Hey guys and gals, after 40,000 plus miles I have my first problem with my Fury. I noticed a small bit of gear oil on my rear wheel and swing arm, I figured it was from some road grime. But after a while it had been getting worse. I have just put new tire on and resealed the rear diif with Honda parts, It still leaks. I took it back apart, the lube is coming from where the drive shaft goes into the pinion housing. Almost as if the gear lube is following the threads of the pinion bolt. Am I missing something here?

Could try rtv on the splines. Been known to leak if not

[Clueless]

Is it oil, or is it grease ?

Did you have the final drive off, and drive shaft out ?

What do you mean by "resealed the rear dif with Honda parts "?

There is an oil seal on the driveshaft, may have been damaged if the shaft was out. (if it is 90 wt)

There is also an O ring on the flange drive, where it (wheel and drive flange) mates to the final (if it is grease) usually works its way down.

Did you recently refill the final, there is a vent tube inside the dust ring, between the final and the wheel. If it is overfilled, oil will blow out the tube.

Hmm, mine seems to be doing this with gear oil since i put the sumo kit on.

It's the "O" ring in your pinion. after that many miles, it's time to replace when you start to see the leak. which will come out the front of the pinion, you will see the fluid on the inside of you rubber diff cover.
