Here is a link to a web site that sells it.

As you can kind of see it is not a needle.

* For recessed fittings where hydraulic couplers can't reach
* Cup-shaped 0.22" diameter tip
* 0.31" body diameter, 3.15" length
* Locking sleeve
* For hand-operated grease guns only

Below are needle type adapters.

 

Hmm. Shopping around on the internet, it looks like I'd have to pay at least $23-30 for the complete set. But all I'd need is just the recessed lube adapter. I wonder if it's worth it for just one zerk.

 

I checked online and it looks like it is about $100 to buy a new u-joint.

 

I bought a recessed lube adapter and it does help some on the front U-joint of the front driveshaft (I take the right shield off and get it from the right side), but it does not work at all on the rear U-joint of the front driveshaft, as I can't get it on the zerk straight on.

Unless something like a Lincoln 5859 90° Angle Hydraulic Coupler Adapter can do the job, I suspect that the rear U-joint of the front driveshaft of the 2005 Kodiak 450 can't be greased.

But that U-joint doesn't turn at much of an angle (if it did, I might be able to grease the zerk) and it might last a long time anyway.

 

Here is a testimony from a Kodiak 450 owner:

Hey. I know the U-joint you are talking about, and no I have never greased it on any of the 3 Kodiak four-wheelers. I don't see an easy way to get to it either. One four-wheeler now has over 16,000 miles, and the other two have 15,000 miles each--and we are still getting along real well with them. We take care of them, but use them hard--most of the miles are over hills checking cattle, crossing the river, or pulling various things. We've changed a few tires, new brake pads on the front, couple headlights, and 1 new battery. The most important thing we have found is to keep the oil changed regularly--we change at 1500 miles or about every 3 months.
Best of luck with your purchase. I think you will really like it.

 

I see that this topic has been I busy topic since I posted last. I wish Yamaha would pick up on the frustrations and provide a more user friendly solution for a routine maintenance thing like this.

Anyways - The Thexton 418 as I posted above and similar manufacturers of that kind do fit the rear drive shaft and rear suspension bushings. I forgot how much of a pain the whole process is especially the front shaft. When I greased it last week I did end up removing the right side shield off and use the needle type to grease the front U-joints. I used the right-angle coupler for the rest. The coupler does snap in kind of tight. When you first slide it on, you think you got it then the grease discharges everywhere. When you look at the pic in the link posted above you will notice that the inside cutout has a slight taper to it then a pocket (near the U-shape end). Push the coupler onto the zerk far enough unit the zerk seats against the U-shape part, you should feel it pop right in and no excess grease should flow from the connection. It's also stubborn as you pull it off of the zerk as well.

And my 2cents about the 15k on Kodiaks, Wow - I can't see not greasing fittings with that kind of mileage. Do they own the older models without IRS?

Hope that helps
