You, or your mechanic need to examine exactly where the play is - easy to do once the wheel is off the ground and the car securely chocked.
Agreed, also if the bolts were refitted and the shanks had worn, the joint will chatter. In the previous DVSA tester manual, it had expressed that many suspension designs have a "Built In" amount of play. Mercedes Benz Sprinter for example, this rule will apply to generate an advisory for any design with slight play or even wear based on the movement in relation to the diameter of the ball pin itself. Thus, a ball joint can pass with a level of play on any component - Drop links, lower ball joints, track rod ends ETC.
I make no claim to allowing slack / clearly worn out joints getting a pass, but the manual has a section relating to the permissible play.
