Judder uphill even slightly one

[Mack89]

Hi, I have a juddering on my Audi A6 C7 2012 CVT transmission on uphill even a slightly one, on even road or downhill its change the “gears” faultlessly. I have change the lower control arms and the ball joints, the gearbox oil as I thought was contaminated and still have the same judder, today I have checked the left axle as I still have a clunk noise on the left passenger side on small potholes or uneven road ,so I have rotate de axle back-forward and its move with a click sound, is that could be a sign that the axle its bad and it does judder and clunking on potholes ? I have added a video of the axle move and clunking. I could not upload the long video but I hope it show the problem
