Looking to see what everyone uses as a grease/lubricant for their trailer jack shaft and Zerk fitting for gears?
I have used bearing grease on the shaft and other times even WD40 which I understand the WD40 attracts dirt, contaminants. So I dont use WD40 anymore.
For past jack shafts (exterior) I have owned, I also have used Boeshield T9 for the shaft or a spray silicone.
The jack also has a Zerk fitting for gears, which some say use a type of chain lube or a lithium based machine grease. Or marine grease like a Quicksilver 2-4-C with PTFE.
What do you all use for the shaft and gears?
Thanks in advance.
