Now I began to do the front suspension, and discovered an strange fact:
Ball joint fasten to the bottom of track control arm on P7.
I looked up a similar place on P3 - a flange of ball joint fasten to the top of track control arm.
In WHB and P7 original parts I see as in my P7. At P3 I see another solution, but this is on rivets - i.e. from factory...
What's right? (I fasten ball joints under arm as in manual, but decided to check)
P7: Ball Joint flange under arm
This i see on P3: Ball Joint flange upper than arm
