ROFL!

Close, but no cigar.  Yes, there should be a clip in there holding the yoke.
But that clip won't prevent the tire from tipping out, gravity does in
normal driving.  There is about 3000-3500 dry pounds in a Corvette depending
on year and model, and one-fourth is on that tire approximately.  Because of
the camber angle on the rear tires, pressure is always pushing IN at the
yoke.  You'd have to be pulling some hefty lateral acceleration to make the
axle pull out.

Still, it is good to have that clip installed and to get the old one out of
the bottom before the gears eat it.

Assumptions:
3500 lb car (car, occupants, gas, etc.)
.8 G max lat acc. (typical of C3)

At .8 G, you would have 1280 lb force at the rear tire inward, creating 640
ft. lb of torque (moment).
The weight would create 875 lb force at the rear tire upward, creating 510
ft.lb of torque (moment).

So at .8 G, the point just before the tires break away, you would create
enough force to pull the top of the tire outward.  However, we don't have
forces for the pivot bolt of the torque arm and we don't have forces of the
shock absorber, both which would resist the tire pulling out.

At .4 G, still very spirited driving, you would have 510 ft lb rotating the
trailing arm assembly into the diff and 320 ft lbs rotating it out, meaning
the axle stays in.

Plus what you said about planes is true.  As the tire tips out, the moment
to push it in increases because the moment arm on the weight force increases
as the line the weight force passes through moves outward from the pivot
point (strut rod).  Also, as the tire "tips", the inside lip lifts and
reduces the lateral acceleration it can achieve, reducing the force, and
letting the tire go back to a normal position.

The bearing is blissfully unaware of this.  What affects the bearing is wide
wheels with improper offset (backspacing) that allows the weight to achieve
a greater moment on the bearings.  An extreme deep dish wheel creates a lot
of extra force on the bearings.  Kind of like grabbing a ball bat, then
hanging a bucket of water on the bat.  The further out that bucket goes, the
harder it is for your wrists to hold the weight.  This is something the
coffee can, slot car wheel boys with the rice burners haven't studied.
