O.K. so i was looking at my truck the other day and i noticed that the front wheels seem to extend out from the fenders more than the rear ones. It got me thinking and so i looked at it harder and started looking at other 4 wheel drives and i noticed the same thing on some of them, the front tires extend out further than the rear ones. Can someone explain to me why this is? edit P.S. what is the shock on the front axle for?
