APPLICABILITY

INTRODUCTION:

While performing routine maintenance, Technicians may have a perception of the bushing which is part of the front lower control arm (LCA) as being loose. To help reduce unnecessary repairs, please refer to the inspection procedure to help clarify the rejection criteria for LCA bushings used on applicable Toyota Models. As described in the inspection procedure, a LCA bushing that has partial bond separation between the rubber bushing and its outer metal sleeve does not require replacement. A bushing in this condition will continue to function as designed and will have no effect on the vehicle's operation or control.

Only after the above-mentioned rubber-to-metal bond has separated completely, does the LCA require replacement. This will be evident to the driver in the form of a "clunk" or "bang". Even when the bushing bond separates completely, the driver will not experience any degradation in vehicle operation or control as the bushing remains sandwiched in the sub-frame and held in place by the retaining bolt. The vehicle can be safely operated in this condition until the LCA is replaced.
