Front axle leaking on 2001 4300

[Dicky]

Hi all.
Looked at my tractor wheel this moring and saw oil on the rim. On closer inspection, it looks as if one of the seals in the front axle right above the rim is leaking. Anybody had this problem? If so how big of a job is it to fix?

01 4300 HST 4WD

Thanks

It is not too big of a job.

I have the service manual page on a 4310. Lemme know if you need it. You can also see an exploded view at jdparts

I had the problem. On that tractor there are two different front axles. One has a simple ring to hold the hub in place and the other uses a special nut. The simple one took about 2 hours (not counting building the hydro press to push out the bearings). I had to use more force to seperate the cover plate from the housing than I like, but it will come off. I bought the cd manual and it's price was covered by this repair in savings. If I had the nut version where you have to set it up with rolling torque, I would take it to a dealer.

This happened to me also, but it was due to winding some horse tail hair into the seal. The fluid exited quickly! Not a bad or expensive fix, I took the hub off, and the dealer did the hard work! When I picked it up, it was under $50. I can send you complete instructions also if needed. Good luck, it isn't that bad, you can do it.

On mine it was what I think of as the "king-pin" seal. The one above the gearbox that allows you to steer, not the actual wheel bearing seal. In my case the price of the JD seal alone was over$50. Next time I go to a bearing/seal supplier if possible.

Now as I look at it - both sides are leaking. I got a price on one seal - 47.00! I am beginning to question whether I should take it to the dealer. If anyone has the shop manual that shows how to do it - it would be great to have it. Also, I know there were 2 different axles - how do I tell which one I have and are the seals the same for both?

Thanks

Nevermind, I found the axle it is the S20BZ107 - Shop manual anyone?

Thanks
