Step 1: Jack the truck up
Place the floor jack in the center of the front axle being sure that it is in a sturdy position. Jack the truck up far enough so that while you are underneath it is comfortable for you to work. Also be sure to place the jack perpendicular to the front end so that it will not interfere while removing the oil plug and the oil filter.
Step 2: Placing the jack stands
Step 3: Remove the oil drain plug
Step 4: Removing the oil filter
NOTE: Any oil that is spilt onto the floor during steps three and four use kitty litter to clean it up. Just spread the kitty litter over the spill and let sit so it can soak the oil up.
