Just did one last night on an 2002 QX4. Took 4 hours to do oil and filter, air filter and fuel filter.

The fuel filter is located just behind of the rear axle and in front of the spare tire. 2 hose clamps and 1 bracket holding it in place.

The plugs are alot of work and time consuming if you don't have the right tools to make it happen. For the driver's side 3 plugs you have to remove the throttle bottle and the hoses that are in the way. On the passenger side there is some wiring harnessess that have to be moved to get at them. All of the plugs are about 6 to 8 inches inside the block and have a coil pack on it. Do not break these, there are expensive to replace. Each one has a wiring plug which needs to be disconnected at the time of removal.

The oil filter is behind the plastic shroud underneath the front and cannot be reached from the top. You have to be under the truck to do this. While you are there, under the truck, drain the oil.

Have fun.
