one of the autoX "technical" inspections is to hold the tires and shake. if you feel any play, things are in real bad shape... Naturally as you know, many things could be the cause
the wooo is an indication that the bearings might be going.
The camber going positive when lifted is normal, unless excessive (more than 2 deg? Hard to eyeball, though).
When you lift, rotate the tires, if they have kind of a "bump" instead of rotating smoothly, definitely bearings.
Unless Lazlong have better check methods
Now, is that for serious?!?
