2002 Bonneville CV joint question

This is a continuation of my earlier post from early September 2007. The car is a 2002 Bonneville, 3.8L with 122K (automatic). Anyhow I had asked a question concerning vibration during acceleration. Merlin2021 suggested checking front strut and control arm to see if bent. Didn't notice anything, but while checking this I noticed that my CV joint on the passenger side has 1/16" side to side play right at the inner joint (outer joint is solid). I know the axle assembly needs to have angular movement as the suspension moves relative to the frame, but I don't think it is supposed to move side to side. Could this be causing the vibration during acceleration? Anyone have any ideas?

Thanks,
