When working on the prop shaft I set out to remove the two Hardy Spicer joints. The one at the front, splined end, came out no problem, the other end was more corroded, two circlips came out easily. Unfortunately the other two eyes broke off. I had to use a dremel burr to weaken the clips enough to lever them out. Care is needed to avoid damage to the housings.
Having managed to remove the last bearing cup it became clear why it was so difficult. From the condition of the older joint, it appears to be an original Austin, with a K number, it looks as though it ran out of lubrication at some time. I have not seen wear like this before! I wonder what it sounded like?
A good guide to replacing Hardy Spicer joints can be found on the Cornwall A7 club website. http://www.austin7.org/Technical%20Articles/Hardy%20Spicer%20Propshaft/
I have found the new roller bearing cups are 5 thou larger than the old ones. Not a lot but with the old ones a tight fit it has taken a lot of careful work to get the fit right.
