Honda CR-V 2006: Rear diff needs new oil?

Honda has told us that they have been in contact with you and that you have been advised that oil changes are done on a time basis, and that “scheduled maintenance changes define the maximum time before oil is to be replaced. Where an oil change is required earlier, this remains a maintenance issue. As a gesture of goodwill, Honda covers this oil change if it occurs during the vehicle's warranty period.” We were further told that “the design of the differential on the CRV model incorporates friction plates that require lubrication. The differential oil will deteriorate with use and this can cause the friction plates to stick slightly on full lock/turns or if the front wheels lose traction. The symptom is a vibration in the car, this vibration will certainly not cause any damage however to eliminate the symptom there is a process recommended by the Honda factory that our Dealer network follows. The process requires flushing and replacement of the differential oil particularly between the friction plates.” I would suggest you take this information to your Honda dealer and ask why your car needed the earlier oil changes that were done.
