### Condition

Some customers may comment about a creak/pop noise coming from the rear of the vehicle. This condition is most apparent during a twist-ditch maneuver, such as entering a driveway or an aggressive acceleration or braking during a turn.

### Cause

This condition may be caused by movement between the rear stabilizer clamps and the rear suspension support during certain types of maneuvers.

### Correction

Install rear suspension support insulators, P/N 22614408, onto the rear suspension support (in the area of the stabilizer shaft clamp upper rectangular holes), using the following procedure:

1. Raise and support the vehicle.
2. Remove the nuts and the clamps securing the stabilizer shaft to the rear suspension support.
3. Install a rear suspension support insulator, P/N 22614408, onto the rear suspension support at each of the rectangular stabilizer shaft clamp holes. With the open end of the insulators pointing upward, slide the insulators upward onto the support through the clamp holes.
4. Install the stabilizer shaft clamps and hand start nuts.

Tighten
Tighten the nuts to 53 N·m (39 lb ft).

5. Remove the vehicle support and lower the vehicle.
