The whole drive shaft shakes while putting into reverse

Sometimes the bump is way harder than other times.
Could it be the leaf springs bushings if they were bad?

Is anyone else seeing the axle twist forwards? It looks at first like the flange or pinion is jumping but the more I look at it it looks like axle wrap.

Engine moves rather than axle until hit hits something and then all that momentum gets transferred to axle which wraps the leaf springs up a bit.

What could cause this?

Realistically no.

We can take guesses all day.

Do this and get back to us:

Hmmm.
While taking a video of engine from center front of truck;
1) Rev the engine quickly while in neutral.
2) Rev the engine quickly while in drive, foot hard on brake.
3) Rev the engine quickly while in reverse, foot hard on brake.
Post results.

As much as that engine moves, you have a bad or loose motor mount.
