Steering gear box leak??

[viper700]

Ever since the lift pump died and I had to manhandle the steering wheel to move it the steering gear box has developed an annoying drip onto the garage floor. I talked to the local dealership today and they wanted $650. It was $375 for the pump and the rest for replacing the pump and realigning the front end. Is there something I can add to the gear box as a stop leak? I gather that they don't have a seal to replace to stop the leak? It will leave a spot about an inch in diameter over night.
