My 56 1/2 ton has the same problem...I bought the rebuilt kit
for the steering box and was disappointed that it didn't help much.
I then had my wife sit in the truck and turn the wheel back/forth
without actually turning the wheels. I noticed a lot of slop in the
drag link-I replaced it and it took care of alot of the steering play,
but I still had problems when I hit a bump. While installing the
monoleaf springs, I found the problem. On the rear of the front
springs, which is the stationary side, the bushing had pretty much
work through and the spring eye had an oval apperance. When I
would hit a bump the complete axle would shift 1/2 inch or so causing
the truck to dart to one side. After replacing all the darting when away,
and it is much more pleasant to drive... Wayne
