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 fit interface between the bearing and the IDS shaft, and combined with a bearing that has around 0.5 Y of torque to rotate (TTR). Correction Perform a road test to diagnose fretting noise. Identify if the noise is at the front intermediate shaft housing. Replace both the IDS shaft and IDS bearing housing. 1. Try and replicate the customers complaint maneuver (generally the noise is heard while coasting and without brakes being applied). 2. Install Chassis Ears. – Identify if the noise is at the front intermediate shaft housing. 3. Once the noise is confirmed and isolated at the front intermediate shaft housing, replace the IDS shaft and IDS shaft housing.
