I'm going to be replacing a tub/shower (leaking) Diverter Spindle and Flow Control Spindle washers, packing nut, etc. Should I apply Plumbing Grease to any of these parts when I install them?
 
The only fixture that I know of that calls their stems spindles are Symmons.

a little grease on the stem threads is okay. nothing on or in the balance spindle part of the unit.

Just a touch of lube on the diverter o-ring.

Silicone lube recommended due to plastic parts.

Had trouble with that particular diverter. Had to double up on the O-rings

Yes, it's a Symmons.
Thank You. In my case it was the diverter which was leaking heavily. The new one that Symmons sent to me is working fine. The o-ring under the packing nut had a little seepage. The instructions say to use a wood or lag screw to remove the old diverter. I saw a youtube demo and the presenter had a tool with a threaded end to do this. I never thought that a lag screw would be in a plumber's toolkit.
