Cylinder shaped part dangling near rear wheels on Mazda 3

The dangling cylinder-shaped parts near the rear wheels are likely components like the rear shocks or exhaust hangers, which can be dislodged or damaged after hitting a severe speed bump. Attempting temporary fixes with steel mesh tape and exhaust putty is generally unsafe and ineffective for structural or suspension parts, and can prevent the vehicle from being safely driven.
