Dana 60 rear end rebuild - need experts help/advice !

[Green Machine]

Just bought a D60 3.54 FF posi from a board member here from a 71 Suburban. We are going to install it in our 1971 C20 2wd. Axle appears in nice shape, but I would like to install new seals, check bearings, etc before installing. I have had quite a few other rears totally apart c10 12 bolts and others so I know general prodecures. Specific questions :

1. Hub removal - do I need a special socket to remove and install the big hub nuts ?
2. Proper preload procedure and initial lube recomendations for the hub bearings during installation ?

3. Should I remove carrier to check bearings or are these usually OK ? If I remove the carrier will it be a major fight on this big baby to get cups and shims back in ? What is the torque spec for the caps ?

4. Pinion seal looks like it has been leaking some, but not bad. I don't have a socket that big but could get one if my 1/2 drive impact would take it off. How hard is the yolk pressed onto the pinion spline ? Puller required here ? I have a small puller I think I could use. The main question here is if it is going to be a major pain to fix I just might leave it alone, but do the pinion bearings go bad often on these ?

5. Axle hub seals look like they might be $25 each, any tips besides a special tool to install them ?

6.Posi unit seems tight, not planning on going that far, so are these usually good to go if tight and passes a close visual inspection ?

7. I know how to do the brakes, but are there any other suggestions on what to check to general tips on these ?

Thanks for your help, I just want to do ths once properly.
