Why does the Bora car make abnormal noises when driving on bumpy roads?
2 Answers
When abnormal noises occur while driving on bumpy roads, chassis-related issues should be considered. If the rubber bushings in the chassis are abnormal or damaged, they lose their cushioning effect. Without this cushioning, connected and supported components will produce abnormal noises as the tires encounter bumps. Aging rubber bushings: Aged rubber bushings can also cause similar abnormal noises. Excessive ball joint clearance: Excessive ball joint clearance can also generate abnormal noises. This is usually caused by the lack of lubricating grease for the ball joint due to a broken or depleted dust cover, leading to dry friction between the ball joint and its socket. Over time, this creates clearance and results in abnormal noises.
My Bora also experienced squeaking noises on bumpy roads last year, which was quite annoying. After some research, I found the most common cause is aging suspension components. Leaking shock absorbers or deformed springs will produce thumping sounds, especially noticeable when going over potholes. Also check chassis parts like tie rod ends or control arms for looseness/wear - these will creak when subjected to bumpy vibrations. Don't overlook tire issues either; insufficient pressure or deformed wheels can transmit vibrations to the body, causing noises. Another possibility is loose or sticking brake calipers that rattle during vibrations. This problem should be fixed promptly as prolonged neglect affects handling safety. I personally tried checking for uneven tire pressures, but it's best to get professional diagnosis at a dealership for thorough suspension/chassis inspection, along with steering system checks.
