years ago, I got a coupler stuck on a zerk and ended up yanking it out. (My signature approach is impatience and premature application of force). After that episode, I put the lock and lube couplers on all my grease guns to guard against it happening again. I don’t even want to think about the possibility of yanking out that difficult driveshaft zerk.
So to answer your question, yes I use the extended L&L coupler. It works well, but it is a close fit and the alignment has to be right on. You probably already know this, but the zerks on both ends of the drive shaft are in alignment, so you can use the easy one as a guide to the position of the difficult one.
I tried using a needle. It just made a mess, like you experienced.
Has anyone tried to use the Longer LockNLube XL Coupler to reach the grease zerk on the 1025R driveshaft U-joint? I tried the needle dispenser and it would not go into the joint...just made a mess around the grease zerk.

Don't think you can get a normal grease gun onto either the front or rear driveshaft Ujoint on the 1025R nor 2025R. Had mine done at 200 hours by JD coming and getting the tractor (on the 2025R; never did the ones on the 1025R). JD had to remove the driveshaft to grease them. You have to turn them almost 90 degrees to get a normal grease gun onto them. There are ones that you push against the zerk but do not lock onto it, but you gotta have a good, straight shot at it. These are the only ones that would work on these zerks.

I didn't have any problems greasing the front one on mine either using a standard grease gun, just lined it up with the hole and stuck the hose tip on and gave her a couple of squirts, no drama. I had been putting it off because of all of the stories I had read on here about it 😂
Might be a tad harder with a hose but it's not like it's deep in a cave. It's only about 1 to 1-1/2 inches inside the frame. I had more trouble lining it up since my 3rd Function SCV plumbing runs near the flywheel and I needed to use a screwdriver to move it.
I just turned the driveshaft using a big screw driver in the rear u-joint.
The 3rd SCV plumbing prevents me from doing that. Need to use the teeth in the flywheel.
The XL will work, but you have to drill out the hole you have to go through so everything will line up perfectly. I drilled mine out to 1" IIRC. I used regular bits, but I would have used a step drill bit if I would have had one at the time.

The second picture I have the LnL locked on the grease fitting and you can see how much of the barrel of the LnL is still visible.
I cannot get on even the rear driveshaft Ujoint of the 2025R with a regular grease gun or LockNload. JD had to remove the shaft (after removing the instrument panel(s). You pretty much have to turn the Ujoint about 90 degrees to get a regular gun onto it. There are other types of tips to use, but I've never found them too useful.
