Can some please advise ! Fitted New set of Ball Joints from Mini spares my Garage has failed them on the Retaining Nut ( High Tensiel Nut and Spring Washer), apparently No Locking Mechanism , they have said It should have a Nylon Locking Nut , Minispares are disputing this so I have no M.O.T right now .
Garage said to drill an eight hole through nut and add a split pin through ?? seems like they dont know Minis ?
stuck what to do next.
