Owners of these vehicles will be receiving two notifications. The first notification, which began in may 1998, will provide an interim repair procedure until parts become available. This interim procedure can be completed by owners or their dealers. It specifies that the lug nut torque must be verified to be 100 lbs. Then the lug nuts need to be tightened an additional 1/8 to 1/4 turn more. There will be a second owner notification, which is expected to begin July 20, 1998, under which dealers will inspect the wheel studs and replace the wheel lug nuts.
