Knock, knock, knock! That's the sound you hear when your sway bar links are not doing their job. Links are a common service item due to either worn or over compliant bushings/ joints and possibly bent or snapped centre bodies. Upgrade from the old units to Whiteline sway bar links with superior features that outlast and outperform the original equipment.
