[man from africa]

not being mechanically minded and unable to do myself could anyone advise how much it will cost to replace fork seals.33000 miles and started to get vibration and noticed one of the seals leaking.am i correct in my assumption that this will cause the vibration.was lovely and smooth now not.many thanks

I'm not sure how a leaking seal would cause a vibration- pogoing front end, yes, maybe also a sticky action if one side moves much easier than the other.
Tank slapping, at the extreme end, if provoked.

Can't think of a way that this would or could cause a vibration, though.

Anyhow, if it's leaking it needs replacing, so why not do that and see what else you find once you've got the legs out?

One thought, is it just vibrating under braking? (Cause that would just be discs).
