It isn't too bad of a job. I have a 99 4x4. The filter is on the
driver's side next to the frame, about in the middle (front to back) of
the vehicle. The most difficult part is getting the filter out of the
clamp. The clamp isn't really a clamp because there is no way to
unclamp it. When I finally got the filter out I shaved down the inside
of the clamp with a dremel tool just a little bit, so that it would be
easier to remove the filter in the future.
