Chevrolet C60s - Front Wheel "shimmy"

[Phil Waterman]

Hi

Like everyone else this is a puzzler, would be interesting to measure the caster of a CMP that dose not shimmy so what are you using to measure caster and camber?

My C60S is the best driver of my three with no hint of shimmy. Just had it out this morning running along on fresh asphalt roads at 50-60 MPH it is just as smooth as you could want. I don't have a front end gauge unit to measure what the various angles. Suggestions on what type equipment you are using and I'll check around.

My C60L and HUP will shimmy but it is well above their comfortable driving speed neither of these trucks is really happy above 45 MPH.

As other people have said the geometry of steering is complicated, may not even be the front springs at fault but flattened out rear springs changing the angle at the front end.

Cheers Phil
