I haven't bent dogbones or axles, but that's not to say it can not happen. Take yours apart and see if you bent it. On my old car (TC5), when I had a wobbly wheel it was because I bent the rim, or the hub got play where the bearings mount.
Just got the new body support/shock tower and dual bellcrank in. I do like the body support shock tower. The dual bellcrank is very nice, however I have already shoegoo'ed my BLS551 servo to the chassis, so that will be a no-go. One must flip the servo 180º so that the arm is on the outside. I think I will end up buying another chassis and servo to test it out rather than undo the servo.
