Rear Camber Adjustment
- When major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed and strap the vehicle to the hoist.
- When performing work in the engine compartment or under the vehicle, ensure that the hood is fully open, or opened to its secondary latch. When the hood is opened to the secondary latch, the vehicle will disable the remote start features from the key fob and OnStar mobile app. Failure to open the hood, or open the hood to the secondary latch while doing a repair in the engine compartment or under the vehicle can result in inadvertent vehicle starting which could result in personal injury or damage to a vehicle.

Refer to Safety Glasses Warning
The lower control arm to the subframe retaining bolt (1) and nut (2) eccentric washers (3) are used to adjust rear suspension camber.
Nuts with micro-encapsulated thread sealant must be discarded after removal.
The lower control arm to the frame retaining nut (2) is not to be fully tightened until after the rear suspension camber has been adjusted.
Before checking and adjusting any wheel alignment angles bounce the vehicle to settle the suspension at normal ride height.
The weight of the vehicle must be on a level surface such as an alignment rack and on all four wheels before fully tightening the bolts and nuts that have been partially tightened. Failure to comply with this requirement may adversely affect the ride and handling characteristics of the vehicle.
Do not allow the lower control arm to subframe retaining bolt (1) to turn while tightening.
