The problem
NUTS USED TO ATTACH LOWER CONTROL ARMS, REAR SPRING AND SHACKLE, AND REAR SHOCK ABSORBERS DO NOT MEET SPECIFICATIONS AND COULD "STRIP".
Risk
STRIPPING OF THE NUTS IN THE REAR SUSPENSION COULD REDUCECLAMP LOAD ON LOWER CONTROL ARM, WHICH COULD ALLOW THE ARM TO DETACH, RESULTINGIN LOSS OF VEHICLE CONTROL AND AN ACCIDENT.
What owners should do
REPLACE LOWER CONTROL ARM ATTACHMENT NUTS AS WELL AS REAR SPRING AND SHACKLE, AND REAR SHOCK ABSORBER NUTS.
