Another AWD Question
Does anybody know what the ratio of power is to front wheel versus rear wheel drive on the AWD vans under normal highway conditions, and what does the ratio change to when the system detects slippage on the rear wheels? I have been told several different combinations by the dealers.(Anywhere from 70/30 to 90/10 under normal conditions).
I used to own an AWD Vanagon and the ratio was 90/10. The AWD worked great AFTER it kicked in, but if you started to slide on a corner, the AWD was too late in adjusting and the fun began!

You did not mention what vehicle and year you were looking for, but my owners manual for my '91 Aero states a 70\30 rear\front normal driving ratio with it adjusting to compensate for slippery conditions. It also states it is approx. and of course will vary do to conditions and mileage on components.

No.
This is my first 4 wheel\all wheel drive anything. It works very well and mostly seamlessly. My first encounter was on hard frost almost ice. The Aero just hummed along and then slid sideways a little. Difference was the front started first. I have over 30 years of two wheel driving and I'm used to the backend coming around. Recovered fast though. Next was sharp left hand on ice, backend came around I got out of the gas and it straightened out real well. Third was ice so bad it just came around anyway. But the Dean Omega Plus tires I run handled it real well.
Had one time on dry pavement I had the front do the little hop catch because it wasn't unloading. Put in new transfer case fluid and no more problems.
