Heard they are related to bushes and since i'm replacing my rear bushes, i'm considering replacing the droplinks (recommended to do so when replacing bushes)....
the droplinks connect your swaybar to the suspension strut.... worn droplinks make a knocking sound when you go over bumps.... if you grab your droplink and try and shake it side to side, and it makes a noise, then youve got worn droplinks.... if not, then youre in the clear
