I have a Saginaw Power steering box that has a bad leak. It looks like the leak is coming out of the back end of the box where the Steering column enters the box. I have read a few threads about this but have found no answers. The box has 71-75 Impala written on the side of it. Is it worth it for a newbie like me to try and fix it with a seal kit? or should i just replace the whole box?
