There was a lot of slop between the wheel spindles and steering tabs on my 1631. Today I looked into it.
It turns out the "tapered pins" that hold them together were roll pins and they were broken. The pictures is of the better pin, the other was sheared into three pieces and must have been barely hanging together.
A 5/16" bolt gives a good fit through the hole. On the front side the tab is welded on right at the hole and I needed to re-drill the holes so the bolt would pass clear through. I ground half the head off two bolts so they would pass in from the front along the tabs. Then put nuts on the rear with some red loc-tite to make sure they stay put.
