the customer complain is there is a knocking noise so i check it and find that the control arm ball joint was very bad and i also try to explain to the customer that it is not safe to drive, and so they declined fixing it and took the car seeing how bad it is anyway. only in about an hour it was back on a tow truck and now it needs more the just the ball joint because it now needs an axle which was fine before. we just stuck them back in place to get the car off the tow truck and in the shop.
