My mechanic told me the front links on my van are broken. What are they and what do they do?

Answer 1

if he said that the front sway bar links are broke, They are for keeping the van level in the corners. If they are broke the van will lean when you turn corners at higher rates of speed.

Answer 2

sway bar links the sway bar is abar that goes from one side to the other if one wheel goes up it lifts up the other wheel so the car is more stabe on turnes
the link is a bolt with bushings that go from the bar to the lower controle arm
