My 1938 1/2 ton has a leaky steering box. Not quite sure where the leak is coming from, but when I fill the box with 160 weight, I get a nice puddle on the floor after a few days. The steering feels pretty tight, so my question is whether or not I can re-seal the steering box without doing a total overhaul. Can I just pull out the box and replace the shaft seal (I'm assuming that's what's leaking) ? Thanks
