I have an L2201DT Grey Market and I had the same problem only leaking quite a bit worse ! This a fairly easy repair. You can take the complete outer hub off of the axle assembly and put it on a work bench to repair . I bought all of the seals and gaskets from Tractorsmart on line . Ordered parts for an L245DT. Just keep track of the "shims" as they set the back lash on the gears .This will be a good time to drain and fill the complete front differential and outer "knuckles" This is not rocket science. Quite straight foreward repair .No special tools required . Tractorsmart has an on line parts manual that you can view and print out the page you need so you can see the "blown up" view of how it assembles . I refilled mine with 90-140 gear lube. I was affraid if I used a thinner lube , it might seep. Mine was quite worn and wobbly . You should repair the leak before it gets real bad like mine did . Wish I had taken pictures now ! Do not be affraid to take it apart yourself . I do not know if your L2202DT is a direct cross to the L245DT like mine was . I don't think Kubota would design a different "knuckle" for each tractor. Mine is 24 hp I think. D1101 engine. Let me know if I can help you in some way. By the way , I fixed mine a year ago and it has not lost a drop of oil yet. Bone dry !!
