Anti-roll Bar Link (Drop Link)

It has ball joints or bushings at each end. It is one of the most common worn suspension parts. It transmits forces that limit body roll. A worn link usually makes a knocking or rattling noise at low speed over uneven surfaces, often heard more on one side. Checking it is easy: with the wheel on the ground, grab the link and try to move it; any play or a torn ball joint boot means replacement. Many links are inexpensive and quick to change.

The link passes movement from the suspension to the bar.

Worn links cause rattling over small bumps. Replace with the suspension unloaded if specified.
