I have Alfa Romeo 159 (939 2.4jtd)
I just want to know if i can change only ball joint on lower arm like in other cars ( buy and screw up) or ball joint is part of arm and must buy it whole. My have excessive play and whistle (stops when injected lube). I was looking for but nowhere find ball joint to buy and any video or conversation about this. Everybody just buy new arm.
