My daughter is looking at buying her first 4x4. It is a 2003 S10 Quad cab. I am new to having a 4x4 myself. This truck is in southern KY and they have no snow on the ground right now, she wants me to go down with her Saturday and help check things out. I have a full size 03 Silverado and I can clearly hear a clicking sound of a switch when I engage and it is very obvious that it doesnt want to turn well on dry pavement when 4x4 is engaged. I am assuming that we will either be on gravel roads or dry pavement Saturday. Any advice on thourghly making sure the 4x4 is working properly would be much appreciated. Still learning. Thanks Mike.
