Farmall H front end knocks

When I'm going down the road and hit a bump or the front end bounces there is a metal on metal knocking noise. I'm sure some sound might be normal but probably not this much. Sounded like the front pedestal was loose and I actually did tighten it up a bit. I went through and repacked the spindle bearings and checked them. My sense is the noise comes from the upper bolster shaft having too much verticle motion. I didn't get the sense that the shaft was moving front to back in a loose bushing.
I've never had a Farmall front end apart, what are some of the common solutions? Might the fix be as easy as taking off the bolster cap, removing a cotter pin, and tightening a nut above the thrust bearing? As always, I appreciate the help.
 
My H with blank rims and wheel wedges on the front was clunking now and then and it turned out that the rim bolts were loose so that the rim was able to rotate on the hub. I am not sure what sort of noise loose 3 loop rims make.

There's an upper bushing, a lower bushing, and the sector gear in the upper bolster. If anything is loose, the front end should be wobbling all over the place.
 
There is no provision for adjusting the vertical end play of the upper bolster shaft. The weight of the tractor keeps it in place. If the noise is really a problem you may want to consider slowing down a bit for the rough spots.

The end play can be controlled by installing washers between the steering gear and the upper bolster. You must maintain a little end play because the gear has a taper fit on the upper bolster shaft which must get tight before all the end play is gone while tightening the retaining nut.
 
That knocking sound is at one of the front rims; lug bolt loose.

Just about drives ya crazy don't it? :>)
