What it does
Shocks and struts control how the springs move, keeping the tires on the road over bumps. 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
- Replace shocks in pairs on the same axle, and get an alignment after strut work.
- Strut mounts: Often worn at the same time.
- Alignment: Needed after strut replacement.
- 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.
