So I just recently purchased a new to me 1950 8N in really good shape. Runs excellent, hydraulics are great, trans is smooth etc, needs one rear axle hub and seals replaced due to a minor leak and a slight play in the hub. And one tire will be replaced for a piece of mind. Holds air but is really dry rotted. Paid $1250 for it with a blade. Anyway it has been driving fine and then the other morning it was 6 degrees out, I started it up just fine let it warm up and started off. It would not turn to the left past center, would turn to the right all day long nice and smooth then back to the left until the wheels were strait again but no further. I managed to get it into the garage. Parked it for a day and then went out to look it over and low and behold it would easily turn in both directions again. What could it be? Could something have been frozen in the steering box to cause it? Should I tear down the steering box and rebuild it? Would hate for it to happen when I wasn't right at the house and able to just do a lap around the house to make it into the shop. Any suggestions. I literally have had it about a week. So my shop manuals are in the mail and will not be here until Friday.
