What is this?
I've been trying to diagnose suspension noise, not finding anything obvious except this. Would whatever this is deteriorating be my issue? I can't find any part number for this.




Searching for noise, have you checked these:
#1 ball joints
#2 sway bar bushings
#3 stab. links
#4 control arms

Notice the part fits the next generation W212, not listed for the W211

I wish I could find a properly fitting bottom isolator for use with the Bilstein B6.

#1 ball joints <— NUMBER 1 CAUSE OF SUSPENSION NOISE ON W212

My car just ate the serpentine belt so focusing on that first before returning to this.




Replace your suspension wear items when you get a chance, all together or one after the other, just like your serpentine belt, tensioner and idlers.

Good luck with that serpentine belt. Unless the belt is really old, a shredded one is usually caused by a bad pulley. Mine was a failed idler bearing.
