Does anyone know if you can disengage the AWD system on the 97-02 CRV's? I am curious to see if you can, since it is all electrical i figure there must be a way. your answers are appreciated.

Hi,
Actually, all 1st generation ('97 to '01) CR-V 4WD systems are mechanical and not electrical or electronic. I also believe that the 2nd generation models, '02 to '04, are also mechanical. The only way to disengage the system would be to physically disconnect the drive shaft, (or "propeller shaft", as Honda refers to it), from the rear differential case. If you want to read about how the 4WD system operates on the CR-V, I found a very informative web site called www.HondaNews.com. You have to navigate through the site though and find where it says "archives", but I just tried going there again and the page I wanted to point you to isn't currently working! So, I will give you a brief run-down on how the system works: The drive shaft is connected to the rear differental via two clutch packs with fluid in between them. When the front wheels are turning at about the same rate of speed as the rear ones, there is no pressure being generated between the clutch packs. But, if the front wheels are spinning FASTER than the rear wheels, pressure is then put on one clutch pack, which in turn creates pressure on the other clutch pack via the hydraulic differential fluid, and causes the rear gears to engage, thus powering the rear wheels. It also stated that this system works very well with anti-lock brakes being that the 4WD inherently will disengage when the brakes are applied, because all wheels will be stopping or slowing down at about the same rate when you brake due to the same amount of brake pressure being applied to each wheel. Make sense? Hope this all helped. The CR-V is actually an ingenius, yet simple design! That's what makes it so great! Did you also know that the 2.0 liter 4 cyl. engine that's in it was designed to be smaller on the outside then a normal 2.0 liter engine? It's also lighter! And Honda says that they set out to make a 2.0 liter engine that has the outer dimensions of a 1.6 liter engine! AMAZING!! They did this by pairing up the cylinder bores in an unorthodox way! Instead of having the normal 9mm spacing between the cylinders, there are only 6mm between them! And they had to use other techniques to give strength to the engine block due to this smaller spacing. But I read that this engine block is extremely sturdy and rigid due to these techniques in design! (Yes, I now perhaps know way too much about nothing! LOL!!!)
All the best,
