Does anyone have a cutaway view of the rear axle bearing/seal area of a '70 4/4 rear axle assembly. Mine has started to leak and I want to replace the seals. I don't have any problem doing the repairs but I don't have a clue as to what is in that area and what is involved in performing the maintenance. I could take it apart and figure it out but I'd really like to know what I need before I start to minimize downtime. The workshop manual is useless and I can't find out anything from my usual sources. Thanks.
