Hi,
I watched the video. It really seems like you have a bad CV joint causing it to jump like that. I realize you replaced the left one, but have you inspected the right one? Also, are the splines on the axle fully seated?
That is what I would be checking. If you find the axle/CV joint is the issue, here is a link that shows in general how it is done:

If you look at the attachments below, they include the directions and pics specific to your vehicle for replacement.
Let me know what you find or if you have other questions.
Take care,
Joe
