Improvements have been made to the area of the front linkage pins. The diameter of the bracket bore fixed with pin has been reduced 0.09 mm (0.0035 inch) from the current diameter. The smaller diameter will reduce the amount of radial play in the front. Refer to Illustration 1 for a location of the pins. The improvements are effective with the February, 2011 production.
