I was afraid of that.  I assume the fuse referred to essentially turns the car in to a front wheel drive.  I got both the owner's manual and a Chilton's on the car, but don't remember seeing reference made to this, though I did not read them straight through.  Can I drive it as a front wheel drive with the fuse in for an extended period?  Is the $1000 an estimate for having the work done?  Is is something I could do myself?
