Yes the shifting is normal, I've noticed the same thing. The anti-sway bar is designed to move a little, your 1/8" is good.
I'm always sure to check my mounting brackets and end links with every oil change.
As far as the grease, I also use the marine grade black grease.
BTW, I've had my Addcos for over 2 years now.
