To keep lint or dirt from getting onto the damper rod parts, do not wear gloves while working on the damper rod.
Set the lower shock mount in a vise with a piece of wood or soft jaws to avoid damage.
Unstake the damper rod end nut with a file as shown.
Be careful to file the end nut by hand so that the O. D. of the rod end is about 10 mm (0.4 in). Be careful not to over-file.
Turn the end nut back-and-forth in 1/4 turn increments until it loosens, then rotate another 1/4 turn and repeat turning back-and-forth until the nut loosens completely.
If the damper rod is cracked or damaged when removing the end nut, replace the damper rod assembly with a new one.
