Never thought of that. I just assumed the centering hub held the weight.

Grease or oil is completely changing how the torque and that stuff works. A joint works by stretching the bolt like a rubber band and the friction under the head and between the threads keeps it from slipping.

Greasing the threads reduces the friction which greatly magnifies the torque you can apply to the stud, which means you are stretching it much farther than designed. The lower friction in the threads also means it is easier to loosen or come off completely if it gets loose.

Biggest danger is work hardening and snapping the studs off.

I used to oil mine too before I learned all of this.

I love the Canoo pickup truck look. I normally don’t buy new cars but that one is really tempting.

Look up barrier creams. Not as good as gloves but I assume they would get into the cracks and pores of your skin and prevent things from soaking in so deep.

Might still have to wash things off the surface but could help with those dark dirty lines that never seem to come out or gasoline that is so hard to remove.

Only used them a little myself.
