Reading the CR-V forum...seems changeint the differential fluid at 15,000+/- miles is "normal." 
So...why not have that listed in the routine maintenance schedule? Asshats...
My Odyssey has 250k miles. I believe I have changed the transmission fluid three times. Not sure what the difference would be with the CRV cause I thought all the Honda engines were basically the same. Just ask why manual says 90k and they want to do now?
