You need to get underneath the vehicle to understand it.
The springs sit between the trailing arm and the body.
The differential is bolted to the subframe.
If you remove the differential mount with the vehicle sitting on it's tires, the diff just sits where it's located...........on the underside of the subframe. It cannot move downward because the springs are under compression and the subframe cannot be lowered in this condition.
When the vehicle is sitting on it's body, the trailing arms are hanging downward and the springs are attempting to drive the subframe to China.
Now, when you loosen the differential mount, the springs will send the entire rear subframe, with the attached diff, downward. This is why you must support the diff.
The procedure cannot be done with the vehicle sitting on it's wheels.
