You do not want the metal sleeve rotating on the metal shaft. This will squeak and wear the shaft. Energy Suspension bushings do not twist like a rubber bushing. They have to rotate. And they like to squeak doing that if put together dry. Use the lube they supply.
While they are a handling improvement over rubber, I just don't care for them in control arms, and would never use them on a lower control arm. I use them for strut rods and sway bar links
