Work on the rear axle continues.
Diff case opened, the cleaning & assessment has began. Insides of casing were OK, but both the seals and bearing cones are not & will need replacing. I have ordered the seals from Ross Prince but feel I only asked for the fibre ring and will also need the metal part too.
The pinion seal parts are knackered also. Once again, I will have to revise my parts order. As you see, I had to fight the metal bit to get it out.
Didn't find any evidence of what had damaged the shorter axle end, and the differential itself seems to be OK. One of the bearings has some rust pitting on a number of the rollers and will need replacing.
