My '13 C300 Mercedes makes a noise when I turn right or hit the breaks.Any idea?

Probably not the mechanic that said it needs both the struts and the control arms. Sounds like he is just covering his butt. I'd get another opinion from a Euro shop. Use this link to find a good one near you. https://repairpal.com/repair-shops Alex

sounds like control arms are probably making most of the noise but would need to look at it. You can call Charlotte for an appointment at 609-689-0688
