All the suspension fasteners are marked as ‘replace’ by Honda in its service manual when you replace suspension arms or dampers.

Ball Joints connect suspension arms and knuckles. Ball joint boots protect ball joints from water and dust.

Castle Nuts are fasteners that connect suspension arms and knuckles via ball joints.

Stabilisers are attached to the chassis by rubber bushes and brackets, and attached to the lower arms via drop links.

As you are aware, the suspension ASSYs are no longer available.
