hi guys, i'm getting a knocking noise from the drivers side front wheel, on a facelift M sport. had the car MOTd the other day and got told i required a ball joint. just wondering if i can just replace the ball joint on this side or should i do passenger side too. plus is there in any other components i could change whilst the car is on the ramp in regards to the suspension. also where would be best place to purchase the parts from. sorry for all the Q's
. thanks in advance
