I just installed a Auburn posi in my 60 C-10. Even though I used my old R&P, I replaced the pinion bearings and races, as well as the carrier bearings and axle bearings. Had I not done that, it would have been fairly easy.

If you've never done it before you will need to read, read, read, all the articles you can find, like those on the Richmond Gear and Randy's Ring & Pinion websites.

I have lots of specialty tools and a 12-ton press, and I don't know how you'd install carrier bearings w/o a press. If you replace the pinion bearings and races, count on another 3-4 hours. You will need a very long pipe wrench to hold the pinion yoke in place while you hit the pinion nut with enough torque (300-400 lb/ft) to compress the crush sleeve to set pinion bearing pre-load. You'll also need a 0-60 in/lb torque wrench to measure pinion bearing pre-load.

The easy part is setting backlash, and I just spent 2-3 hours earlier today doing that until I got the shim packs just right.
