... when straight and also during curves to left. Please help, No noise when I am going around a right curve. Checked wheel-wells thoroughly and no contact points anywhere. Was expecting them on right side. Wondering if it is a bushing gone bad. Car has 135k miles. Any ideas?

 

my suggestion would be to jack up all the tires and check them for noise

jack up the frount passengers side first, and spin the tire (as fast as you can without giving yourself a hernia). after that, grab the tire and see if it has any play it it (shake it from side to side, if its alot of movement, or makes alot of noise, its the wheelbearings, and they need to be checked by a professional, repacked, or replaced)

I suggest you to get a Factory Mercedes Manual.

It has all service and maintenance instructions, step by step.

A great help, hope this will help you.
