My steering box is leaking at the out put shaft for the steering arm. Can this be fixed with a seal? Or do I get a used one at junk yard?
Do you
have the same problem?

Welcome to 2CarPros.

Chances are it can, but there could also be an issue with o-rings and seals. Also, excessive wear on the output shaft can cause the leak. With that in mind, I am going to provide the complete overhaul directions and pics to help. I hate to say it, but it would be a lot easier to get a new one. LOL Regardless, here are the directions which include the replacement of all seals. The attached pics correlate with the directions.
