Axis cab seats you need to:

[scrubjaysnest]

check for a broken or missing cotter pin/key on the cab swivel seats. Found the passenger seat was a little wobbly today and the cotter key was gone.
This allowed the castle nut to back off. This was a bad memory for the DW, thought we were back in the 1989 class C we had.

Found a small piece of the cotter pin; tightened the nut down and got a replacement cotter key from the supply we always carry.
