Subject:
STEERING COLUMN SHAKING/VIBRATION


Model and Year:
1992 G VANS



Some owners of 1992 G-Vans may experience a shaking/vibration at the steering column.

The cause is due to several changes in the steering column assembly for 1992 model year G-Vans.

A pencil brace has been developed to minimize steering column/wheel vibration. The pencil brace should be installed from the cowl to the lower steering column bracket, behind the existing pencil brace.

When installing the new pencil brace it is not necessary to remove the instrument panel. The pencil brace can be installed by removing the instrument cluster. This will allow access to the cowl for the upper attachment stud.
