[QUOTE=SlowPro48;265437]Sambo, I'm getting too old and tired to argue anymore. Nowadays I like to agree with people. I'm curious though - exactly how do you think the spring helper insulates the axle housing from the frame by being in contact with it? Do you know how a mechanic's stethoscope works?

Will you agree with me that the axle housing is attached to the frame via a center link, a lateral link and two trailing links, which provide a pathway for vibration (sound) to be transmitted to the frame?

Will you agree with me that the shocks and coil springs also provide a pathway for vibration?

Will you agree with me that these pathways exist whether the spring helpers are touching the axle housing or not?



I think you said it with the tuning fork analogy. The spring helper blends all these contact points into a balanced resonance and thus makes the clatter from this symphony of metal arms less prevalent .

I can attest from personal experience that it works this way. And my wife who has no particular mechanical expertise mentioned it first...."what did you do to quiet this thing down." Installed the missing spring helpers....simple.
