Disconnect the steering cable from the motor to determine if it's the steering cable or the motor itself. Either one could cause the symptom you're experiencing.

You could try and take the lower pivot pin cover off. It's held in place with 4 bolts I believe. Clean and lube the lower part of the pivot pin. Clean up any corrosion with some fine emery cloth. To get to the upper portion of the pivot pin, you may need a motor hoist to lift the motor up to do the same.

Sorry to be the bearer of bad news. The king pin is carried in two plastic sleeves inside the yoke. With age the aluminum yoke corrodes and the corrosion squeezes the plastic sleeves which then bind the kingpin. No amount of grease will ease the problem.

The only cure is to hoist the engine, disassemble the mount, and drive out the kingpin. Then either replace the plastic sleeves or redrill them to 1 1/8 inch after cleaning the inside of the yoke and coating it with anti-seize. Sand the kingpin smooth unless it is so rusted that replacement is necessary. Regrease and be VIGILANT about periodically greasing to prevent the problem again.

This is a long and frustrating repair of a simple problem. Good for a winter project.
