Simple question but can't get a straight answer even from the dealership. I have a 2002 F350 Diesel. I have an electronic 4 wheel drive switch inside the cab. I also have locking hubs on the front wheels. My question is do I leave the locking hubs on automatic or on "on" when I want to engage the electronic 4 wheel drive. And if I have to leave the wheel lock on "ON" then what is the sense of having an electronic switch in the cab. Thanks for any info.
