Does anyone know how to do this? or a mechanic that can do this cheap?

any pics of damage or better description

Front or rear?

Will depend on the clearance behind the hub. If there is space, its a simple job, if there isnt, the hub may have to come off, which may destroy the wheel bearing in the process.

Try PMing Chris Gilly on here....

Cheers stuy,

I can do it cheap at my garage, ring/text me on 07783628321 or PM me on here.

It will either have to be pressed out(no problem to do!) just the whole hub will have to come off(realativly easy, ive done tonnes of these), or i could be hit/drilled out depending on which axle its fitted too.
