Rocky F70 2.8D Pulling rear diff?

I've downloaded a rocky manual, but unfortunately it is missing a few pages.
Does anyone have the pages for removal of the rear diff?
I found a "how to" of rear bearing replacement, but the pics are missing. I thought it would be pretty similar to my Zook, but I'm not sure.

The pics went missing when OL dropped pics off the site. Thats my How To for the rear wheel bearing.

What do you need to know, how to replace a wheel bearing, or how to pull the diff centre?

Both are pretty easy, by a reasonably mechanically minded person.

We are just trying to pull the diff center. I pulled my Zook apart a couple of weeks ago no worries, but we are having trouble pulling the axles out of the Rocky.

Don't know if the 70's different to a 75, but min just slid out easy as pie once everything was off - wheel, brakes, etc. :? Housings not bent or anything?

It's all out now, just needed a bit more persuasion.
But now we've realised we need it back together to pull out the front seal. :roll:

OK, it's all out now.

Here is the offending part.

There was heaps of movement in the tail shaft, which led us to believe the bearing was shagged. On pulling it out, it appears OK, just some light pitting on the rollers.

Could the bearing have been not installed properly? Too many shims maybe, pushing the rollers away from the outer race, causing movement?

We'll pick up some new bearings and seal today and reinstall it.
