Thanks jesmed, Some great info.
The photo with the article you referred me to looks like a Fourth Generation CRV.
Your '99 is a First Gen. and I’m looking at the 2nd Gen models which ran from '02 to '06.
Midway through these 2nd Gen models some significant changes were introduced in the 2005 model year. A 5 speed auto replaced the previous 4 spd, (giving slightly improved mpg), traction control and Vehicle Stability Assist were also added along with the “smarter, cam-driven 4WD system” under discussion.
While the article you listed does seem to explain the cam-driven details of the AWD system and its control of the hydraulics involved, if it is, in fact, referring to the 4th Gen models, it still leaves some questions about the specifics of the '05 models.
Here’s what I found in Wiki’s vague explanation of the 4th Gen “all-new Real-Time all-wheel-drive (AWD) with intelligent control system”.
“The 2012 CR-V was launched at the 2011 Los Angeles Auto Show and it is powered with a 2.4-liter i-VTEC inline-four engine that puts out 185 hp and 163 pound-feet (220Nm ) of torque at 4,400 rpm along with an all-new Real-Time all-wheel-drive (AWD) with intelligent control system.”
Sometimes the tech notes don’t explain nearly as much good ol’ real life experience.
Comments from owners like you offer an earthy quality of reassurance that is unmatched by engineering stats-
"But basically, the mechanism is still mainly the old proven hydraulic system with some bits added. I’ve never heard of a problem with it.
All you need to do is make sure to change the differential pump fluid at recommended intervals with genuine Honda fluid and you’ll be fine"
Ah, I’ll be fine. That’s what I wanted to hear. Now if I can just get a seller to commit that to writing. There I suspect the “Ah” will change to “Nah.” Yah?
Thanks again jesmed for your helpful advice and research.
