I have an earlier 4250 MFWD (s/n 6277)and the steering assist cylinder pin broke out of the steering knuckle. Upon inspection the steering knuckle casting is very worn and the end of the cylinder looks to be oval. Looks like grease wasn't getting into where it needed to be The other side has almost wore the pin through (pic) but the casting is not worn and looks like new parts will fix it. However it looks like I'll be looking for a new knuckle casting on the bad side. Has anyone ever ran into something similar? Do you think the cylinder end is salvageable? According to the parts book, this cylinder setup wasn't used on later serial numbers.
