Wheel Alignment Angles: Shimmy
WARNING: This page is about a different car, the 2011 Jaguar XKR, 2011 Jaguar XK, 2010 Jaguar XKR, and 2010 Jaguar XK. However, it is still accessible from the selected car via links, so may be relevant.
Shimmy, as observed by the driver, is rotational oscillations of the steering wheel which may come and go over time, generally resulting from wheel and tire imbalances.
Shimmy can be experienced at any speed but generally between 80 to 145 km/h (50 to 90 miles/hour) and is most often experienced on smooth roads at steady speeds.
