Replying to: blueiedgod (Oct 30, 2009 9:11 am) So what you are saying is Honda 4WD and Subaru all wheel drive is different. To me they are both 4 wheel drive and do well in snow etc. have never heard of another vehicle that requires 15K intervals to change Diff.Fluid. I am thinking of a a 09 or 10 CRV. and wondering if they have changed or in my view fixed this problem,And also they might try to alleviate some of the road noise!

When both front and rear wheels are turning at the same speed, the pressure between the pumps is neutral. Once either of the wheels are turning faster, it creates pressure differential between the pumps and activates the clutch pack.   The benefit is the lighter weight, and lower rolling resitance, which results in higher fuel efficiency.   The system is proven bullet proof with regular maintenance. It was originally installed on the mid-80's Civic Wagon 4WD vehicles, and has been continually improved, but essentially is a dual pump system.   While Subaru's system is always on. It is simpler, but takes a hit in the fuel economy department.

Replying to: sabfish (Oct 29, 2009 7:39 am) Hello sabfish,   thanks for the info on this tsb for the 07 crv. my aunt has a noise coming from the rear diff and when she was at the dealer, they were trying to charge her for the fluid change and inspection fee. Good thing I found this thread and mentioned to the service advisor about the tsb.... well, let's just say that they suddenly remembered that a tsb exists for this noise.   thanks, tony
