Am doing condition inspection and found ball joints seized although it appears they do move in operation as they are a little shiny at joint.
I called Curt and asked if it was necessary to get the joints freed up cold.
He responded, concurring with my feeling, it is not necessary.
The system is like a solid pipe system except there is wiggle room at the joints when hot, no need to be free cold. There is no cracking and ball joints are more for adjusting at install to get them in right position exiting lower cowl.
Under temperatures in flight, lub will not stay in the joints.
The pipes must be at least 400-500 degrees at the balls.
