steering column rebuild

On the pin at the coupler end of the shaft there’s no need to remove it unless it’s worn or damaged. The lock plate wheel can be removed by removing the pin then the shaft will come out the bottom end of the column tube. There is a service tool that will press the pin out for removal of the lock plate but would be hard to come by. You could beat the lower pin out like SGbarracuda stated and remove it from the top.
