P/S pump bearing?

hey guys
my power steering pump pulley seems to have some excessive play.
makes a loud ticking noise when the engine is running.
any idea what sort of place would be able to rebuild it?
or how hard would it be to rebuild myself?
pwr steering works fine so maybe just a rooted bearing?
cheers, john

 

yes just replace the bearings and seal. It is pretty straight forward.

 

Anyone know the part numbers for the bearing and seal?
Or where to source them from?
