Leaking Power steering rack. Off and ready for repair Brisbane

Ok i pulled the rack off (mmm with the steering shaft still connected its hard to remove) I wouldn't mind fixing the seal leak myself.(its at the front of the pump thing i.e see photo) ...just keen to hear of any advise from other members out there who have done the same??before i go get snabbed $600 bucks for a full reco which it probably doesnt need!!!

Cheers group :)
