Malcolm,
You say that the seal contact area on both axles is very corroded. I think that it is pointless putting new seals in as they won't stand a chance of doing any sealing. Is it possible to precision cylindrical grind the sealing surface which will help the size mismatch and give the seals a chance to seal against a smooth surface. As long as this will not be the smallest diameter area of the shaft it shouldn't affect the strength. You just need an engineering shop with a big enough capacity cylindrical grinder to do the job.
