I had my car start off with this sqeaking you are describing, and then it turned to a clunking. Dealer said it was the rear links and replaced it all under warranty.

Noise is now gone.

 

Update - took it in last Friday and they said it was the drivers side rear control arm. They did pack some grease in and it improved the noise issue quite a bit. They replaced the arm today and the issue is resolved. I do think greasing them up if you start hearing squeeks or pops may help for most.

 

I think it would work if you only had a grunting / squeaking sounds, but once it starts clunking or popping it's usually too late.

 

so I took my car in, but the dealer couldn't re produce the noise. I noticed that noise in the video only occurs over large speed bumps and big pot holes now that it's warmer (50 degrees). According to the video are you guys sure it's the rear sway bar end links? I'm thinking about going after market.

 

This is what they replaced
