Hi, Help needed please. 2014 ML63 W166. Trying to diagnose Front end knocking sound. All front has basically been replaced. The other day, Both upper control arms. Both lower control arms. Both Lower ball joints. Left and right swaybar linkages. Air suspension struts were replaced 2 years ago. Knocking coming from right drivers side. (In Australia) Could the right strut have a fault? Car is balanced and lifting etc. You’ll hear the video the knocking sound. We can’t work out what else it could be. Thanking you.

You need a mechanic in person to answer your questions about your issue. Nobody here will be able to assist to what exactly is going on, besides guessing.

thanks for the reply. I get that but was hoping someone may of experienced the same.

Someone messaged me privately and said it could be a faulty strut. I’ve take it for a drive with raising the car. When it reaches the height. There’s a knock sound from the drivers side strut. Driving with it raised pretty much stopped the knocking sound. Also the car started lowering on its own. Sounds like strut is faulty.
