This is how I installed my Warn Manual Locking hubs, from RRO. I simply followed the instructions supplied with the hubs, but decided to do a mini guide because I participate in another forum where many members don't speak English, so following the instructions suplied by Warn can be complicated. It is also to show that it is easy and straightforward, as long as you have the proper tools.
Some hubs need loads of grease to work. It says in the instructions that these come properly greased from factory, and that they won't work properly if more grease is added. So don't do it

.
To install, you need to lift the car to extract the wheel:

These are the hub locks, with the body on the left and the cap on the right.

You need to remove the plastic cover. There is a small dent (in my case it was just under where it says "20mm" on the disk support. To remove, the tool used to remove the wheel nuts works great.
By the way, I'm not sure if you have this same black cover, maybe it is somewhat different, but it shouldn't be very hard.

This is what is under the black cover. You need to remove the six bolts (in the photo they have already been removed). You need to keep these, you shall use them later. Like before, this metal part needs to be removed by inserting the wheel tool in the dent.

Now you have the factory locked hub in your hands. You can get rid of it if you want, I'll be keeping mne just in case. Take care, NOTHING can go inside and get things dirty. It would have been a good idea to clean the car before starting (not like me).

Take the hub body:

Put it in:

Now is when you reuse the original bolts, with the rings that Warn supplies in this order:

Now you need to simply bolt them in, at the torque specified on the page. I didn't have a torque wrench, so I just pushed hard and will solve that later.

Now is when you put the cap. There is a gasket that comes with the hubs, you need to use. If you don't water, dust etc will go in and thats not good is it? Be sure that the "key" is in 4x2 postion, if it is in 4x4 it will be very difficult to put the cap in (you would be trying to compress the spring):

You need to make sure this...:

...goes in there:

Now you simply use the supplied bolts and use the torque wrench to the specified torque:

Now wheel goes back on:

These are the old parts:

Now go start on the other wheel

There, all translated!
