the tires are starting to "hook up".
Chevy done that on 4-wheel drives so when your off road with it the rear wheels are always grabbing a couple inches of un touched ground where the front wheels did not touck. That is called tracking. It's so the rear wheels don't run in the same place that the front wheels run. Better traction.
It is what the rear wheels bolt to.It is what the rear wheels bolt to.
During forward acceleration on any vehicle (front wheel drive or otherwise), more of the vehicles weight is transferred to the rear of the car, making the rear of the car heavier. This is undesirable in a front wheel drive car because there is less weight over the drive wheels to produce traction (causing the front wheels to spin)
That is how GM. built it so when you are off road with it, all 4 wheels don't run in the same place. The rear tires are always grabbing untouched earth and it pulls better when in the mud. Good Ideal don't you think.

Wheels man
On the rear wheels, it's the axle.

might have misaligned or loose wheels
Wheels require balancing.
for better traction!!
On a rear wheel drive vehicle, the rear axles transfer power from the rear differential to the rear wheels.
