The front wheels will sometimes wobble while driving on the road what pin or parts are worn that would cause this? I would like to get this fixed before it causes some other problem. Thanks in advance

It could be the spherical bearings in the ends of the cylinder. It could be the hollow pin at the base of the cylinder. It could be the king pins. If the front tires dont lean slightly outboard at the top the kingpins are worn. It could be a leaky cylinder piston. Probably not the piston because that usually causes other steering issues

Jack up the front left and then right to check for play in the king pins or the pivot assemblies. If they are loose and the bottom retainer is missing the pin can fall out on a road bounce. There is a local guy here that can rebuild the pivot assembly if the pins wore into them. They were not the heaviest build fwd axle of its day. Need greased but even greasing does not prevent issues from rising on them overtime.

If it hasn't had king pins and bearings at least one time already, I guarantee it needs them. Those tractors are now 40 years old.

Kingpin bearings for sure. Having mine done now. AGCO has the bearings. The balls and sockets in the ends of the steering cylinder are probably worn out too - mine are.

Thanks guys, I have rebuilt the steering cylinder and replaced all of those parts and welded up the pin hole so that part is good. Looks like king pins and bushings, our two 8050s don't have this wobble that is why I was asking. Thanks again for the help.
