Has the original ball joint been left loose for some time before it was removed for replacement? Could it be that the tapered seat is elongated from the tie-rod flogging around in the mounting bracket? Were the two replacements identical in the dimensions of the taper? were they original AGCO or aftermarket parts? What is the country of manufacture of the 245? I can only find tractors with dual cylinders fitted?
Let us know, regards, Evan.
