If that does not help, replace 3 more times with driving for a day or two in between. If that does not help, then the differential is beyond repair. You can ghetto rig it by removing the propeller shaft and just drive in 2 WD mode.

I thought that was due to the 4 cylinder engine but WOW, this must be somehow related to the 4 Wheel Drive and you can feel it on the entire Drive Train. It is now gone. My only question is if HONDA knows about this, why are they quietly servicing customers? I wonder when the next this will appear again. The Maintenance schedule calls for at 90,000 KM but I ended up doing this at 28,000 KM. I will keep an eye on this and maybe do this FLUSH every 25,000 KM. I thought HONDAs were solid and I am now thinking not to purchase HONDA for my second vehicle. Anymore thoughts on how many people are seeing this and if HONDA has proactively done a Total RECALL on all CRVs to fix this? I checked RECALL web page for Honda CRVs and there is nothing. CDNMECH

CDNMECH Glad differential flush fixed your problem. Although I am not sure how the shaking was related to the differential, unless dealer also flushed the tranny (assuming you drive auto). There won't be a recall since this is not a safety related issue. The noise gives you enough warning to change the fluid. As to the longevity of the fluid, it depends on the amount of AWD action you get, and how wet your area is. There is a breather tube on top of the differential and water can get in, which dilutes the fluid. Generally, people have been changing rear differential fluid at 15,000 mile intervals and auto tranny fluid at 30,000 mile intervals.

On the 05-06 the fast acting cams engage the rear wheel when the front wheels turn faster than the rear, essentially transferring the power to the rear. Then the rest of the power is transferred through the same dual pump hydraulic system used on Honda's since 1986 Civic Wagon AWD (including 1997-2004 CR-V). The hydraulic system relies on speed differential to create enough pressure to activate the clutch packs to connect the rear wheels to the spinning propeller shaft. When fluid is old or contaminated it may inadvertently engnage the rear, and act as if the transfer case was locked in a conventional 4WD system, hence the scrubbing and the noise. When you turn, the inside wheels travel less distance than the outside wheels. This is side to side differential, CR-V has open differential. But, when you turn the front outside wheel travels more than the rear inside wheel, which in a conventional locked 4WD system will cause binding. Here the rear differential acts as a limited slip transfer case, allowing some slip front to rear so that the driveline does not bind. There is a great video on HondaSUV on how the "Real Time AWD" system works.
