I this step we have to apply quite a bit of force to separate/release the latch mechanism containing the metal plate. The first photo shows white plastic part that is held tightly in the metal "V" notch has been released after pressing downward on the metal "shelf"
It took me quite a bit of wrestling to finally get this part separated from the rest of the actuator. In addition to the downward pressure, the insert needs to come outward.
Set the removed latch mechanism aside until reassembly.
