Chevrolet C60s - Front Wheel "shimmy"

[Andy Beevers]

Just to clarify a few details.
The vehicle was designed without the shimmy
therfore should be able to cure the shimmy

The shimmy is when the wheels start to turn left and right by a few degrees on their own, violently.
A steering damper will stop or nulify the problem ( can be fitted) but is not fixing the problem.

As has been said, there must be play somewhere or insufficient resistance to create the scenario for this to happen.
The wheel balance issue brings on the shimmy automatically, so will look into that once the shimmy is sorted, otherwise you need to be at a speed of 30 mph+ and hit a pothole or even a cats eye to instigate the shimmy.
