What it does
Sway bars limit body roll in corners by linking the left and right suspension. Worn suspension and steering parts show up as clunks, wandering, uneven tire wear and a vague feel; fresh parts restore control, and performance parts sharpen it.
Installation & tips
- Fit new end links and bushings with a new bar, and tighten links with the car at ride height.
- End links: Worn links clunk.
- Bushings: Fresh bushings stop squeaks.
- This part affects how the vehicle stops, steers or holds the road. If you are not sure how to fit it, have it installed or checked by a qualified mechanic.
