I'm new to the whole 4 wheel drive thing so please don't laugh (too hard) at my questions. I just put on 285/70/17's on the truck. When I put the FJ in 4 wheel drive I get this lurching feeling when the truck is going under 10mph. Is this normal. Also, when in 4 wheel drive, I put the FJ in reverse it seems to want to stop me. First, should I even be going in reverse in 4 wheel drive mode? Second, if so, is this normal? After pushing the gas to reverse I hear a type of clicking sound. Normal? Please help a newbie.
