This video explains how to replace the rear Axle Seal and Wheel Seal ( Grease Seal). On D21 Nissan Hardbody Trucks equipped with single rear wheel, these steps don't apply to the 1 Ton version that has dual rear wheels.
This is a complete step by step guide for the DIY enthusiast, it covers removal of each item, it also explains how to re-pack the Wheel Bearing and how to bleed the Brake System after all the components have been installed.
The hardest part of this job is pressing the Wheel Bearing in and out, there is a need to use a Shop Press for this procedure, however, you can still do all the other steps and take your axle/backing plate assembly to your local Machine Shop and they can Press the Bearing out and install the Wheel Seal for you.
Doing it this way will still save you money plus it will give you the sense of accomplishment by doing most of the work yourself.
