Per the Maintenance Manual,
"tighten control arm lock nuts until hat section spacers are firmly seated, then
back off until control arm moves freely and retorque nuts to 15-20 ft lbs."
I have soaked the top hats several times with penetrating oil. Today I attempted
to get the hat sections to move. If they are moving it is not perceptible by my
eyes. But, the control arm end-play (in/out at the outer end) goes away when I
tighten them -- only to return if I loosen them. (I did not have my torque
wrench with me to quantify -- I was just working today on getting things
loosened up)
How much torque can I safely apply to the lock nuts? They require a 1 1/2 inch
socket on my coach.

If the top hats are not moving -- what is changing to eliminate the control arm
end-play?
I am aware that the hat sections can be frozen from corrosion -- and that some
have had to use up to a 20 ton press to remove them. Pulling the bogie
assemblies is not a project I can consider at the moment.
Thanks,
