I have been trying to explain what is happening but not very well....

(typical)
Herewith, better pics that explain the wear of concern....
and a tad fazzy...but ya get the idea.

A new swivel hub has been chewed out like this over a period of time...Dennis and I are struggling to work out how this can be happening when you assemble everything correctly and whack the big C Washer on and torque it up.....you still get movement.
As you can see on the driveshaft pictue...the inner bearing has run hot (the rusty portion showed some blueing)....we are wondering now if it has been moving backwards and forwards or maybe turning on the shaft
