I am amazed at the interest my question has generated.
As an apprentice in the garage in the late 1950s, one of my jobs on certain cars; was to jack up the car, support the chassis on axle stands then lower the jack. We then used a bolster chisel to open the spring leaves and a hacksaw blade to spread grease between the leaves .
Then attending the local Technical College, we were told that the friction between the spring leaves produced a natural "damping action".
