The problem
THE REAR AXLE CONTROL ARM LOCATES AND HELPS CONTROL AXLE MOVEMENT; IT ATTACHES TO THE FRAME WITH A BRACKET. THE REAR CONTROL ARM BRACKET ATTACHING BOLTS USED ON SOME OF THE INVOLVED VEHICLES MAY FRACTURE. FRACTURE OF ALL FOUR BOLTS ON ONE SIDE OF THE VEHICLE CAN RESULT IN THE CONTROL ARM DROPPING ENOUGH TO CUT THE REAR BRAKE HOSE. A SEVERED BRAKE HOSE WOULD RESULT IN BRAKE FLUID LOSS AND PARTIAL LOSS OF BRAKING ABILITY.
What owners should do
DEALERS WILL REPLACE ALL EIGHT CONTROL ARM BRACKET BOLTS FREE OF CHARGE.
