Below manual shows the correct way of replacement of anti-roll bar bushings in Mercedes C Class (W204).
Due to untypical original anti-roll bushings attachment, beside of rubber elements additional metal clamps are included in the replacement kit.
Before the original bushings are replaced it is needed to mark their position on the anti-roll bar.
Remove the metal clamp and rubber from the anti-roll bar. The bar needs to be completely cleaned from remaining rubber before new bushings can be installed.
