    Banging Noises when Driving Over Bumps – Inspection & Repair in Hamilton

    Why is your car making banging noises when driving over bumps?

    If your car is making a loud banging or knocking noise when you go over bumps, it is usually due to a problem in your car’s suspension system. However, other things such as engine and transmission mounts are known to cause banging noises.

    Your car’s suspension system consists of several different components which work together to absorb bumps, inconsistencies and impacts. This allows for a smoother driving experience, especially on bumpy terrains.

    There are several different steering and suspension components which can fail, leading to loud noises, shaking and reduced control after driving over a bump in the road. Below are some of the most common causes:

     

    Leaking shock absorbers:

    The shock absorbers work with your suspension system to absorb bumps in the road. Inside a shock absorber, pistons flow through oil to generate heat, which reduces vertical motion in each wheel. Damage to the shock absorber(s) can cause this oil to leak. As oil leaks, the shock absorber will produce rattling or banging noises as you go over bumps in the road.

    Worn ball joints:

    Ball joints are important suspension components which connect the control arm to the steering knuckles. Their purpose is to allow for smooth operation of the suspensions system. Over time, the nylon sockets in ball joints can wear. This can lead to noisy operation.

    Worn steering rack bushings:

    Your car’s steering rack connects to the steering wheel. The ends of the steering rack then connect to the front wheels. Sometimes, the bushings that mount the steering rack in place will become loose. This can lead to loud noises and vibrations when going over bumps.

    Loose engine or transmission mounts:

    Inside your car are several mounts that hold the engine and transmission in place. These mounts carry a heavy weight and this can lead to them failing over time. When they fail, the engine or transmission will become more prone to moving when the car goes over bumps. The result of this is loud banging or crashing noises which are accompanied by powerful vibrations.
