I replaced two front axles, two front sway bar links, two lower front control arms, shocks and struts full front susspension and it rides like a cloud with no harshness whatsoever. I suggest if your Benz is riding harsh look at your struts, axles, sway bars, control arms and do a process of elimination upon inspection of the parts. I paid a great price and didn't have to spend much to get this car really back to an A++ ride. Next is full Motul oils and fluids swap from Moly.
