Hi to all, I have a 2001 LL Bean Outback with the 3.0 engine. In the fuse box behind the battery there is an empty slot marked "FWD". If you insert a fuse into this position an icon on the dash ( FWD) lights to indicate that you are in front wheel drive. This tip was passed on to me by a Sabaru mechanic. There is no need for AWD here for 6 months out of the year. I'm wondering if this mod will improve fuel economy and tire wear? Does anyone have any expierence with this mod? Thanks Ralph
