If a customer with a 2003 and later Pilot or 2006 and later Ridgeline complains of a noise and judder from the rear of the vehicle when turning, the VTM-4 differential fluid could likely be contaminated by clutch wear, condensation or both. This causes the VTM-4 differential clutches to make noise and to judder when turning.

Note: Worn VTM-4 fluid that has not been replaced at the recommended service intervals can cause the same condition. Check to see if the VTM-4 fluid has been replaced at the recommended intervals.

Corrective Action:
Replace the VTM-4 differential fluid.

Required Materials:

Diagnosis:
Do 10 figure-eight patterns with the steering wheel at full lock. Listen for a noise and feel for a judder. Accelerate at the start of each circle to make sure the clutches engage and disengage. Do not use the VTM-4 LOCK button.
