2007 Honda CRV rear differential noise began at about30,000 miles. I took vehicle in to Honda of turnersville, NJ. They told me the noise was due to wear of the rear differential fluid, that it had to be changed whenever the noise appeared, or every 20,000 miles. They replaced the fluid free of charge, and burnished the bearings for the first time, but I was told I would have to pay for the service in the future. I was told it did not represent a safety hazard and that it did not do mechanical damage to the vehicle, nor would it in the future. There is nothing in the service manual regarding this service change requirement. I have noticed significant complaints from other CRV owners on websites and blogs. I have also seen reference to "inferior subgrade" rear differential fluid use by Honda on the same vehicles.

2007 Honda CRV turned out to be very bad on snow and/or ice covered roads. Rear end feels like it wants to kick out to the right. Took it to be serviced and was told the rear differential fluid needed to be drained and the clutches burnished. Drove better after that, 6 weeks later car making noise like a bearing was going out. Was told that my rear tires were cupped due to not having rotated them. Car had 20,000 miles on it. Since tires were already ruined, I waited to take it in again till 30,000 miles. Now the front tires were bald in the center and rear tires still cupped. They drained the rear differential fluid again and again burnished the clutches as well as performed the 30K suggested maintenance. 4K miles later, while driving on bad roads, the rear end once again feels like it wants to slide off the road to the right. Feels like it needs a couple hundred pounds of extra weight in the rear. Oh, forgot to mention, have had the tires replaced and today had it aligned. I have had 2 other Honda's (Accord). Very pleased, but absolutely can't stand this car. I don't feel safe driving it.
