Strange recovery?

Very strange phenomena happened yesterday while measuring on click-clack noise from DIJ of NCP10 TOYOTA Vitz, just replacing wheel with tire right to left each other diminished the chronic problem thoroughly, how come? What were the procedures, replacing drive shafts on both side, doing on hub bearings? Now I know that all the efforts on relatively hard works were in vain remembering the past! Then the most suspicious criminal causing strange noise have to be frontal tires, aluminum wheels? Anyway, constructive axle geometry and wheel alignment are the issues to be verified immediately, otherwise I must drag the bad state of feeling from now.
First of all, frontal camber on both side must be set on standard value, 15 to 30 minutes of angle with driver's weight on the seat, then total toe 1mm would be attained. Remember, as shown 15 to 30, the value should be the same if there are some tolerance in the standard value. Because, the frontal camber value fixed in exactly the same would be a very important and indispensable key to establishing fine wheel alignment adjustment procedures.
Recently happens some mysterious phenomenon that not be explained logically?
It is said that some attempts in the mechanical field is interesting because it's hard to understand and requires some efforts, obtaining several know-hows on the way. Early birds fly away from the nest also this morning immediately after dawn.
