Try picturing it as a cylinder, with machined grooves, where the balls transfer energy, & are able to move in & out (mmmmmm...horizontal...)...then picture having BIGGER balls...after machining...Originally Posted by 89Vette
How does that work? I picture it as the inside of a half-sphere with grooves for the opposite "knuckle". If the boot rips and it's contaminated, doesn't that cause scarring/pitting? How would you "machine" that out?
