Steering Wheel Twitch During Brake Application
If you receive customer reports in the above model vehicles of a steering wheel twitch during slow speed brake applications, replace the hydro-mount or partially hollow rubber style bushings (which ever equipped) with solid rubber bushings. Reference the following WIS documents AR33.15-P-0160R (torque strut removal/installation) and AR33.15-P-0160-02T (torque strut bushing removal/installation).
Note:
Do not replace the torque strut assemblies. Only replace the left and right torque strut bushings.
Note:
The steering wheel twitch condition can usually be maximized during slow speed repetitive brake applications, such as those encountered during stop-and-go traffic or toll booth scenarios. Since ambient temperature may influence the overall affect of the condition, it is important to verify the condition only when the vehicle's engine temperature is at normal operating temperature. The steering wheel rotation/twitch can occur during brake pedal application and or release.
Note:
It is imperative that the condition be verified on a smooth, flat and level road surface, failure to observe the aforementioned conditions may result in needless replacement of the torque strut bushings.
Note:
The originally equipped torque strut bushings (hydro-mount or partially hollow rubber) can deform under braking applications, resulting in left or right steering wheel rotation. The solid rubber bushings have an increased resilience towards deforming during suspension loading.
