|Condition||Some customers may comment on a creak noise originating from the rear of the vehicle. The noise may be more predominant during twist conditions, for example entering a driveway or parking ramps.|

If you encounter a vehicle with the above concern, complete the following steps:

- Using jack stands, support the cradle and remove one of the rear suspension cradle bolts.
- Remove the rear suspension reinforcement.
- Reinstall the rear suspension cradle bolt 7½ full turns without the rear suspension reinforcement installed.
- Using a 3 lb hammer, strike the bolt 8–10 times in a upward motion.
Important: Using anything heavier than a 3 lb hammer may cause damage. Use caution when striking the bolt upward.
- Reinstall the rear suspension reinforcement and a new rear suspension cradle bolt that has not been struck by the hammer.
TightenTighten the rear suspension cradle bolt to 160 Nm (118 lb ft).
- Repeat steps 2–6 on the other rear suspension cradle bolt.
