you might try penrite. at one time there was a link to one of their sites on this page. They have a lube they claim will not leak out of old steering boxes, and will sell in small quantities. It is a little pricey. I ordered one or two tubes, but it has been a while and I don't remember the cost. I am stil getting some leakage, but I don't know if it is the new lube, or the remainder of the old that was still in the box. I suppose if the seals are bad enough, anything will leak. As best as I can remember from when these trucks were a lot newer, they all leaked then and most people just ignored it. It made a mess, but it didn't really hurt anything, and all they were interested in was, did it run? Allen
