steering box adjustment

I bought a remanufactured one probably 10 years ago or so for a B-body and it seemed to me it was no better as far as being tighter than what I pulled out. It didn't leak though so I'm just guessing, and this is my own guess is that all they really do is break it down, clean it up and replace all the seals and gaskets. Other people can chime in but next time I think I'll save up my money to buy new. I put a lot of miles on too as my Dart is my driver so it makes a difference to me.
