Steve,
In a word: u-joints (ok, 2 words). The Spitfire has a universal joint on
each swing axle and these joints wear pretty rapidly. I don't recall what
the official service interval is on these but 15,000 to 20,000 miles is
about the limit in my experience. It is not a very difficult job to do
yourself assuming you have a large vice or a press for installing the new
joints. It does require removal of the axles which if you are not careful,
could lead to a bout with Ship-Fitter's disease!
Good luck,
Mike

P.S. Replace them in pairs. If one is bad, the other is probably not far
behind...
