For the sake of interest I would like to know from you what “all-wheel” means now? We once have rear wheel drive with a differential, i.e. it spins the lighter walking wheel. In all-wheel mode on the front axle the same. Basically I only have on a soft ground 2 wheels that grab and that each on the less grippy ground? The following case: Left wheels stand on bare ice, right wheels on dry gravel. The car should pull, what happens then? Or will be the two differential seperat 100% locked? Then would really pack all 4 wheels evenly?? Do I have a thought error? Nice quiet Sunday I still wish! Gruss Willy
