Replying to: tkay2 (Oct 30, 2009 4:00 am) I believe the scheduled differential fluid interval for 2007 an dup CR-V is 15,000 miles. Even if the poster has to change it every 20,000 miles, he/she is getting more out of the fluid than intended. Honda's Real-Time AWD is different from Subaru's, and comparing the fluid intervals on the Subaru (which is just a differential, not an AWD integral part) with CR-V, is like complaining that apples taste like oranges, when they are indeed oranges. It would be more benefitial to the owners of the respective vehicles to understand what each system is, how it works, and what the differences are before making categorical statements and comparing the two. Just my 2 cents.

Replying to: tkay2 (Nov 02, 2009 2:57 am) Honda's AWD system is integrated in the rear differential, while Subaru's AWD system is in the central differential. Honda uses wet clutches and two pumps to create the pressure to activate the rear wheels. 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) 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 |
