Mercedes W211 front suspension arm - Comparison of old vs new

This video shows the forward arm of the front suspension on most 211, 219, and 230 chassis Mercedes (excluding 4Matic). As mentioned in the video, the rubber bushings did not look bad from a visual inspection, and the left side did not appear any worse than the right side. However, when disconnected from the steering knuckle, it was apparent the left side bushing was in much worse condition. These were original Mercedes parts with 124kmi. The OEM appears to be CFW for these suspension arms, same as the upper & lower ball joints. The joint on the outer end of the arm was still good and had no detectable play. The replacement arm shown in the video is Lemforder brand, and it has the latest upgraded bushing design which is much more robust. The part numbers for the arm assemblies are 211-330-43-11 (left) and 211-330-44-11 (right). Also required are 4 new protective rubber boots, p/n 211-333-06-97 (sold individually), which are to be retrofitted per the WIS when this suspension arm is replaced. The boots the rubber bushing last longer. If buying Genuine Mercedes parts from the dealer, the arms have been superceded to a new number; 211-330-49-11 left and 211-330-50-11 right. I believe the latest version from Mercedes includes the bushing pre-installed (the old version did not include the bushing, but aftermarket brands do include the bushing). Close-up photos of old vs new style bushings will be on my website soon, I will add a link here when those are uploaded. The arm shown in this video has a different name in each Mercedes system. The EPC refers to it as a "strut", the parts systems call it a "strut rod", and the WIS (service manual) calls it either a "torque strut" or "radius rod" depending on the specific document. Pick your favorite term! The new arm shown in the video had the pivot bolt temporarily tightened, to show the torsion action of the rubber bushing. Per the factory procedure, this pivot bolt should NOT be tightened until the car is on the wheels / on the ground, at normal ride height, in "ready to drive" position. Failure to do this will result in rapid wear of the bushing and/or abnormal ride height.
