Ok, for those that maybe interested in upgrading your worn lock outs with something else than the Warn's or the beloved broached spicers, or your like me and looking into going back to a dual purpose rig. The new Yukons may be the ticket for you. Here is a little write up with some pics to show off this new product.
This is the box and the part #. For my application I needed this for a '88 HPD60 out of a F350, now in a '02 WJ Grand Cherokee.
I forgot to mention this also as a selling point for me. The hubs revert to the locked position if broken. This is key if your like me and have broken a hub before and had to 3 wheel out of a bad situation that broke the hub to start with.

Here is what you get in the box. These hubs are not cheap, but the quality seems to be top notch.
Ok. First thing first. I pulled the Yukon drive flanges out and cleaned the hub to make sure there is nothing in there that should not be.
Grease is your friend. Grease everything! The last thing you want is a failure because you ran a hub dry. Just don't do it. Pack and lube everything in this install.
Next you grease and install the spacer. You will see a theme here. Like I said, everything gets greased.
Next we'll install the spring.
Next is the coupler and the driver. This can get a little tricky, and you may have to do some wiggling to get both the hub splines, the stub splines, and the coupler/Driver splines all lined up. Grease these.

You have to get this all lined up, push them up against the spring, and get the small snap ring on the stub shaft. You may need to use a tool like I did to keep the stub from slipping back. I just used a lug wrench from a truck (don't ask what it came off of), but I'm sure a big screw driver would work fine. Make sure that the snap ring seats properly.
Next we are going to install the cam spacer into the retainer. Allign the ears and put it into the hub. More grease.

Next we'll install the hub snap ring to hold the whole thing together.
Check to make sure nothing is binding by pushing on the retainer. It should slide fairly easy with a little pressure. If it hangs up, you did something wrong. I packed the hub with some more grease, and flipped the dial over to fill the ports with grease also. Install the driver dial with the supplied allen bolts and torque to 22lbs. DON'T OVER TORQUE!!! I used blue Loctite on the bolts. The instructions do not tell you to do this, but I use Loctite on every fastener I can. If you use permenant (Red) Loctite on them, well, you're an idiot. You still need to be able to get these off one day. You've been warned.

Now let's make sure that the hub locks and unlocks properly. Twist the dial 1/4 turn to lock and back 1/4 turn to unlock. Everything should be smooth. If it's binding, don't force it! Remove your driver and look to see what you put together wrong.
That's it! You should be ready to go!
In closing. These hubs have to be the best quality locking hubs I have ever put in an axle to date. Everything fits well, the parts are beef. Yukon claims that these are very close to the strength of thier drive flanges. Being that is what I took out of this axle, only time will tell. These hubs are not cheap as I stated at the start of this review, but quality rarely comes with a reduced price tag.
I hope I helped someone understand a little more about the installation of these lock outs, and even if you never purchase or own a set, you'll have a little more knowledge in your hat.
Thanks for reading, or at least looking at the pictures.
Looks good, Jim!
I have to ask, though. What advantage do these offer over broached Spicers? A warranty and parts availability?
The broached spicer hubs are a great option as for the strength. I feel that these will hold there own with any lock out that comes down the road, ever. The availability is what made my decision. I wanted something "off the shelf", and actually designed to be that way. We, as gear heads never leave anything alone. It was nice to have an "out of the box, bolt on". The spicers are a tried and true design and I'm sure they will be used for many years to come, but it was nice to actually follow the instructions and not have to void a warranty, modify 20 year old parts, to get something to work on my rig. Haha.
These have a striking resemblance to the another hub manufacturer.
