final drive leak

[Wheelin]

Hi Guys and Gals -

I've developed a leak around the rear wheel axle nut (see attached pic). Is this an easy fix? What should be fixed? Lastly, are there any videos to assist my repair-addled brain?

All the best,
Wheelin

Try cleaning it good and see if it comes back. That's not technically a leak, more a weap. Can be aggravated by lots of off road vibe and heat. Looks like the seal is on the inside, could be a tough one to do.

I don't ride offroad, but I do ride in SoCal, and it's been pretty hot out here. Sounds good. No harm in trying, anyway. I'm at a service interval where it's time for me to change out the final drive oil, at any point, so we'll see what happens. If an actual repair is required, I may have to take this one to a pro (dang it!). I don't want to screw anything up that's beyond the normal maintenance items. Thanks for your feedback.

If the leak is persistent after you have cleaned it, the only fix is to change 2 new Orings. The pumpkin has to be dismantled to access the Orings. (I have never done this so I can't advice). One of the Orings is leaking but since it is difficult to know which one, just change the 2.

Your tire and rim appear to indicate more leakage. Notice the 'drip trails' in the pic? I would verify the condition under the FD also.

10-4, i’ll take a look at it. I’ve ridden through some puddles, so I had assumed that those puddles had left their mark on the rim, but you’re right, it never hurts to check. Thanks.

Ok, I’ll keep monitoring. Thanks.

I realize that this thread is as old as dirt right now, but I am adding an additional post should other people experience the same problem and come to the forum seeking answers . As it turns out, it stopped leaking. I suspect that the mechanic who last changed the rear wheel prior to me taking over that task got a little zealous and applied too much grease to the splines and axle, thereby causing the leak/weeping. In any case, I’ve not experienced any additional problems.

Me thinks seal #4 was leaking a little and you got lucky. Maybe a little trash got in it???

Could be. I’ve been called trashy before.
