You know I haven’t had the pleasure of replacing one of these seals.....yet. In reading what kots1 says I agree, get it at your local Nissan dealer. I do have one observation, some seals are now made of Teflon, instead of the old style rubber with the little spring. If this seal is a Teflon seal then there is a special procedure for installation.
First you need to wipe the surface of the shaft that the lip of the seal rests against with alcohol, plain old dollar store rubbing alchol will work. Clean that surface throughly. Do not lubricate the seal or shaft with any type of fluid, install the seal dry and perfectly clean. Be extremely careful that you do not nick the lip of the seal during installation, if you have to, use a piece of tape over any sharp edge, depending on how it goes together, obviously you can’t leave a piece of tape in the transmission. Once it is fully seated do not turn the shaft (in this case axle) for a period of about 4 hours. This allows the seal to “set”.
Of course if you look at the seal and it has that little spring around the lip all those instructions are out the window. Those kind do need to be lubed with whatever fluid it will be sealing.
