Summary

12050B - CUSTOMER SATISFACTION (REVISED EXPIRATION DATE). CERTAIN VEHICLES, ALL EQUIPPED WITH A 10.5" REAR AXLE, MAY HAVE A CONDITION IN WHICH THE REAR AXLE RIGHT-HAND SIDE BEARING ADJUSTER CLIP AND BOLT MAY COME LOOSE WITHIN THE REAR AXLE. IF THIS OCCURS, A GRINDING NOISE AND A VEHICLE VIBRATION WOULD BE NOTICEABLE WHEN THE VEHICLE IS IN MOTION. IF THE ADJUSTOR OR BOLT PUNCTURES THE DIFFERENTIAL COVER PAN, A FLUID LEAK COULD DEVELOP. IF ENOUGH FLUID WERE TO LEAK OUT, THE DRIVER MAY HEAR INCREASING NOISE, ADDITIONAL VEHICLE VIBRATION, AND SMELL BURNT AXLE LUBRICANT. IF THE DRIVER IGNORES THESE WARNINGS AND CONTINUES TO DRIVE THE VEHICLE, A SLOW LOSS OF VEHICLE MOTION COULD OCCUR. DEALERS ARE TO INSPECT AND, IF NECESSARY, REPAIR THE REAR AXLE.
