For those working in close quarters, there are 4 fasteners holding the cover on.
One very visible as you first get under the car, two facing the rear on the engine side that are slightly angled and then on in the center rear down in the molded circle that on mine is angled about 40 degrees or so towards the axle.

A nice bright LED spot light sure is helpful too.
