Mine has started soon as I lowered it!
Now the camber bolts are seized in the arms so I couldn't pre load it as much as I wanted to! So I think it's stressed a bush!
I will replace the hole rear arm and bush set up soon! Only way to stop it!
I should imagine yours in the same issue!
Ps to remove a mk5 rear bearing you only need to remove wheel,disc,caliper and carrier then the 30mm nut, bearing will slide off and on easy!
Never has a bearing creak but could be poss if this is happening just when rocking back and forth..
