I would like to install the steering gearbox. Not sure if I should just grease it and re-install it or replace it with a rebuilt one. When I drove the car home it had all kinds of play in the steering. All the ball joints were bad and the Idler arm was shot. When I play with the steering gearbox by holding the rag joint and the pitman arm I can feel no play and it turns freely? What do ya think?
