Condition
Some customers may comment on a bump or thump noise heard from the rear suspension or felt in the floor. The information below will affect vehicles
with G67 Automatic Level Control rear suspension. This noise will typically occur at traffic lights after rapid stops. This noise is due to a combination of
the rear electronic suspension attempting to level the vehicle and the driveline becoming unbound after these rapid stops.

and the Drive Shaft Yoke and grease with P/N 19257121 (in Canada, use P/N 19257122). Reinstall and evaluate operation. 2WD Vehicles - Replace the
