Hi, i have had my c43 just over a month now , and had it serviced the first week i had it, at time of service they replaced a couple of swivel joints, rollbar bushes, 1 damper and an idler bush, i was told at that time that the steering tie bar needed replacing which i have had fitted today, i thought this would cure i clonk sound that can be heard when braking just before the car stops ? i am taking car back to the Merc specialist garage on Tuesday but if any of you could throw some light on what may be the cause it would be a great help ! thanks Leigh
