I've searched, but haven't found the answer. I know how to do it in my Hondas, raise the car on a lift (all 4 wheels), start the engine, put the car in first gear and set the e-brake. If the engine dies, the rear wheel drive is working. I assume this will work for a Subaru, but I'm not sure. Since I am shopping for a Subaru and I know that many people do not pay attention to keeping the tires matched, I would like to be able to test the AWD, preferably without having to take it to a shop.
Please enlighten me.
