Complementary Modification:

Replace sway bar

The stabilizer or sway bar links (sometimes referred to drop links) on the W204 connect the vehicle's front stabilizer bar (or sway bar) to the front strut. Over time, the connecting link wears out and gets play in the ends. When they begin to fail, you may have a knocking noise in the front end when driving over bumps or when steering the vehicle. If you suspect your stabilizer link is going bad, jack up the front of the vehicle and wiggle the wheel back and forth. While wiggling the wheel, listen for a noise from the link. If no noise is heard, place your hand around the ends of the link and monitor for looseness as you wiggle the wheel.

The drop links are NOT multi-directional and can only be used on the correct side so if you are only ordering one make sure you order the correct link for the side of the car you are working on.

Begin by safely raising and supporting the vehicle. Please see our article on jacking up and supporting your vehicle. Remove the front tires. The stabilizer bar is not under stress or pressure so you do not need to worry about things moving with the links off.

The stud on the drop link will spin when you try and remove the nut so you need to hold the stud on the link in place with a T40 Torx (yellow arrow) while using a 18mm wrench to remove the nut (red arrow).

The area where the stud connects to the strut is very tight.

If you have a hollow socket and ratchet tool it will make the removal of the top nut easier.
