Here are some more pictures, I suppose you could install a o ring but I don't think it will seal,
also depending on the thickness of the o ring it might be putting a constant force against
the ring on the end of the axle, if the axle and stub shaft were new you might get a
seal or o ring to work but once you get a little wear in the axle splines then you
get enough movement where I think it would affect the seals integrity, one would
have to try it to see if and how well it will work, again I think the sealing will be
dependent on the amount of wear and movement of the stub shaft in the final shaft
in the trans, I also think no matter how well you think you have it sealed that you
need to take it apart and install fresh grease on the splines I went 3-4 years since I did
mine last, this time they were long over due the grease was black and getting hard there
also was dirt mixed in with it.

I think most of the wear is caused by rust than anything else, fresh grease will prevent the
rust, mine was just starting to show signs of rust, I think if I pull the stub shafts out of the
final shaft in the trans every 2 years, clean and re grease I will be ok, whether or not the
silicone I applied will help the seal or not I wont know until I pull it apart, I cant see where it
would hurt anything.

Close up

Brake disc side, you can see where the silicone has a better chance of sealing against
the nut in later photos

Silicone is right against the nut, should seal good as long as the movement is not that bad.

I think I got too much grease (red stuff) on this side, more than I wanted
I think it will not allow the silicone seal well on this side.


If you guys want measurements let me know I can take them then post if
you want to work on a seal.

And their you have it now its Hoserized!
