Rear sway bar movement, how much?

Trying to determine if any more of my suspensoin parts are defective. Have replaced the rear struts (ones that angle to the front of the car) it was very apparent the bushings on them were gone. Replaced front sway bar brackets and bushings, front left tie-rod and had a allignment done, not sure if they did a 4 wheel allignment, have to get back to them. Back rear tire shows more wear on the inside and tire looks like its cambered in at the top. Question, how much movement should there be in the control arm bushing if any at all and how much movement from the rear sway bar parts, particularly were it connects to the wheel. Would the wheel appearing to be top side in, I'm thinking springs and or control arm bushings.

When testing for movement in a rubber bushing mount, test in the direction of tension or compression of the suspension member. There should be no freeplay. E.g., you may be able to translate a sway bar along its axis through rotational bushings, but there should be no movement in any direction perpendicular to the axis, since the bar twists.
