[Z06] Recall--Lower Control Arm Washer
GM quote:
"Washers that are used along with nuts to attach the lower control arms were made of the wrong steel material. These washers may fracture and become loose or fall away from the vehicle, making it possible for the control arm to separate."
My left-rear wheel is dramatically tilted out and is there is no tread left on the outside of the tire. No wear on the middle or inside. Front tires are not affected. Right-rear tire shows a little bit more wear on the outside, but not as much as left-rear.
It's going to the dealer tomorrow. Any thoughts?
Thanks in advance.

It is a fairly simple fix.
Get it done, only takes a couple of hours.
Good luck!


last five vin#s 118579-127798, got these at my dealer last fall when I had my 04, lower control arm ball-stud washers replaced, time 1-1&half hours. If they have to replace the lower control arms,more time plus alinement. My dealer said he had done about 10 before mine and none needed control arms replaced.
thanks for the heads up, now i must find time to get it fixed
is this a MUST DO ASAP?
the only thing i'm worried about is that they would have to lift the car up, and because mine is lowered with longer bolts and cut bushings, i will feel uneasy trusting the dealership unless i'm there to watch

04043 - Lower Control Arm Washer
2004 Cadillac CTS, SRX, XLR
2004 Chevrolet Corvette
Condition
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2004 Cadillac CTS, SRX and XLR, and Chevrolet Corvette vehicles. Washers that are used along with nuts to attach the lower control arms were made of the wrong steel material. These washers may fracture and become loose or fall away from the vehicle, making it possible for the control arm to separate. If this were to occur on the front of the vehicle, the affected corner of the vehicle will drop and the affected wheel could tilt outward, creating a dragging action that would tend to slow the vehicle and turn it in the direction of the affected corner. The driver could maintain some steering control with the unaffected wheel, but the vehicle control would be diminished. If the separation occurs at the rear of the vehicle (XLR and Corvette only), it could cause unexpected right or left lateral forces at the rear of the vehicle. Although steering of the front wheels would be unaffected, control of vehicle direction would be impaired.
Front or rear control arm separation may also reduce brake system performance and increase stopping distance.
If these events occur and the driver is unable to react in time, a crash could occur.
Correction
Dealers are to install a new nut and washer, and if required, replace the ball stud and/or steering knuckle.
