not sure on your question, but are you missing the locking plates for the ball joints. when i went to Audi(in germany) the schematic on the computer screen showed a locking plate between the ball joint and wishbone
Ball Joint Lock Plates
amount required= 2 total, 1 each side
Part number= 8J0 407 175 (176)
im presuming you could get slip on those ball joints if you corner hard enough without the lock plate
