Replace Sway (Stabilizer) Bar Bushings and Links C CLK Class W203 W209

This repair guide will show you how to replace the sway/stabilizer bar bushings and the sway bar links in the front of a Mercedes-Benz C Class W203 or a CLK Class W209. Mercedes-Benz sway bar bushings and links need to be replaced around 100,000 miles. As they wear and tear, they tend to cause ratling and clunks when driving at low speeds. The primary purpose of the sway bar is to avoid body roll. Because the sway bar is connected to the suspension, every time you hit a bump, it’s not only the strut or shock that takes the hit but also the sway bar bushings and links. Wonder how bad sway bar bushings look? Here is an example:

How do you know you need your sway bushings and links replaced?

You hear knocking, clunks, and rattling noises coming from the front of the car when going over bumps. While sometimes you can visibly see a damaged sway bar bushing or link, this is not always the case. When the sway bushing or links have played due to wear, the sway bar moves excessively, causing clunks and rattles. It could also be that even though the bushings seem intact but the integrity of the rubber bushing is compromised, and thus it needs to be replaced. You will know you need them as the car feels less stable, especially during cornering, and is noisy when driving bumpy roads.

Too many times, the sway bar bushings get misdiagnosed. The front struts get replaced to cure the clunking and rattling. Replacing the sway bar bushing significantly improves the ride quality and is much cheaper and often the problem. So before you let your mechanic replace your struts/shocks, have them check these bushings first. Since this is an easy and cheaper task, you may want to replace these bushing as a wear and tear item at around 100k miles.
