Hi
I have been down the replacing seal route before. Generally it wont last more than a year. If its leaking it is due to mechanical wear of the shaft rather than the seal being the problem. a new seal will stop the leak but not forever.
I have a puller you are welcome to use if we can arrange the MC express from Cardiff to Coventry.
If the fluid is not poaring out you could try some power steering stop leak fluid, have a look on e bay for it.
I cant put a link to it as i will get sent to bed without supper again.
You would be better off saving up for a recon box.
Regards
