John Deer 2210 Tractor Driveshaft Issues. Greasing

I have a 2003 John Deer 2210 Sub Compact Tractor I purchased recently with approximately 260 HRS. It has a full steel Curtis Cab. I ve been reading about problems with the Driveshaft issues and trying to lubricate the U Joints. I ve tried ALL the YouTube recommendations without ANY success! The problem I have for instance with the front Joint is that the Zirk fitting is turned up and so close to the Driveshaft that I ve had 0 Success getting grease into the cups of the joint. I can t really get a wrench onto the Zirk to try to loosen it a bit to allow me to get grease into it. Just too tight an area to work in. Grease everywhere but where it should go. I can move the ball of the Zirk so I know there seems to be nothing wrong with that. I THINK! The U joint that I ve inspected is the front one. It does seem perfectly fine for now. I haven t even attempted to look into the rear Joint yet. What if any other things might I try?? How much work is it to remove the Driveshaft from the Tractor?? Keep in mind I have the Curtis Cab. Is there a YouTube video explaining how this is accomplished? Whereas the U joints I m sure are fine for now but I m worried about in the future! WHAT THE HECK WERE THEY THINKING WHEN THEY DESIGNED THIS AWFUL WAY OF DOING THIS! Anyway any help would be greatly appreciated! Again. I believe I ve seen all the information so far! Is there an adapter other than the common ones that I might try. Thank you all!

I am actually surprised to hear they used greaseable u-joints on those. Most everything in the automotive field went to sealed non-greaseable and seem to be doing fine that way.

A common thing we would do with hard to get at zerks is try to flex the shaft and catch it as it rotates to an out side position. Maybe a small socket of some sort can get at it. Another thought is how hard would it be to pull one end of the drive shaft off and then flex. I know a person shouldn't have to do that but if you are in a desperate position-- Good
Luck.

Look at the needle tip used to grease U-joints in the video. Starting at the 3:40 mark is what would apply to your situation.
Grease needle tip

That was my first thought! We have an 01 JD 4600 and I have never seen anything in the book about greasing the u-joints. My experience is that one that is never greased will outlast one that is overgreased!

Here?s waist I use . They work good for zerks you
can?t get to . I?ve never seen one you can?t pull
ahead a little or back up so that the zerk is in a
different spot so you can grease it

Common problem with the 2210 and I believe
the 2320. The bigger 2520 has a sealed
bearing. The most common solution I've
heard is people would end up cutting a
small hole in the floorboards big enough
to fit a grease gun through. Try
