46 Half Ton Caster Wedges?

[leon bee]

I've pulled the completely worn out frontend from beneath my jailbar project. Man, everything is worn- somebody didn't care much about grease. After I removed the leaf spring U-bolts to get the axle free, I found a caster wedge only on one side. Those big nuts were so tough to get off I had decided that all that had never been apart, but now I want to know about the wedges.

Is this an unusual circumstance, to find a wedge only on one side? Thanks a lot!!
