Bulletin No.: PIP5785 Published date: 03/6/2021 Preliminary Information PIP5785 Whining/Whirring, Whistle, Squeaking, Groaning/Growling Noise Coming From The Front Wheel/Engine Area Models Brand: Model: VIN: Model Years: from Engine: to Transmissions: Cadillac ATS 2017 - 2019 All All All All Cadillac CTS 2017 - 2019 All All All All Cadillac CT6 2016 - 2020 All All All All Involved Region or Country North America Additional Options (RPO) F46 Some customers may comment on one or more of the following conditions at low speeds during driving maneuvers up to 40 mph: Condition Whining/Whirring Whistle Squeaking Groaning/Growling The customer might state this noise coming from the engine/wheel area Cause This condition may be caused by fretting between the Front Intermediate Shaft(IDS Shaft) and the Front Intermediate Shaft Bearing/Housing(IDS bearing). The fretting is the result of having a slip t interface between the bearing and the IDS shaft, and combined with a bearing that has around 0.5Nm of torque to rotate(TTR) Correction: Perform road test to diagnose fretting noise: 1. Try and replicate the customers complaint maneuver (generally the noise is heard while coasting and without brakes being applied) 2. Install Chassis Ears 3. Identify if the noise is at the Front Intermediate Shaft Housing 4. Once the noise is con rmed and isolated at the front intermediate shaft housing 5. Replace IDS Shaft and IDS Shaft Housing, refer to Front Wheel Drive Intermediate Shaft Replacement & Front Wheel Drive Intermediate Shaft Housing Replacement in Si. Parts Information Caution: This vehicle is equipped with torque-to-yield or single use fasteners. Install a NEW torque-to-yield or single use fastener when installing this component. Failure to replace the torque-to-yield or single use fastener could cause damage to the vehicle or components. Note: If the bolts or nuts are found to be damaged or are excessively worn, DO NOT reuse. Replace with new. Note: If reusing the propeller shaft bolts, to ensure proper adhesion and fastener retention, the threads must be free of debris prior to the application of thread locker. Use an appropriate cleaner to thoroughly clean the threads and allow to dry. Apply thread locker to the propeller shaft to ange bolts. Ensure that there are no gaps in the thread locker along the length of the lled area of the bolts. Allow the thread locker to cure approximately 10 minutes before installation.
