Knocking/ banging noises when driving over the bumps Inspection Service

It’s obviously impossible to drive on smooth, bump-free roads all the time. And in as much as rough roads may trigger costly problems and repairs, they can also be helpful in identifying possible faults. Driving over bumps is all too common, but not so the knockin noise that may come with them. If your car runs smoothly on smooth surfaces but gives out a banging noise when driving over bumps, it’s probably time to have a professional mechanic check what potential issues are indicated.

How this system works:

The suspension system contains many components that function to enhance comfort by minimizing impact when driving over uneven terrains. Sadly, these components wear or become damaged over time, a problem often indicated by banging noises in your car as you drive over bumps. Components like ball joints and tie rod ends may however consistently produce this typical noise on other smooth terrains. The noise may also symptomize a different problem, especially when it seems to be produced when driving over a bump.

Why this problem occurs:

Knocking noises can be caused by any of the following problems:

• Loose Brake Caliper: The brake caliper is a piston that ensures the brakes are engaged when the pedal is applied. These pistons are usually kept in position with bolts, and therefore they may produce a banging noise when the bolt becomes loose over time.
• Faulty Sway Bar Link: Also called the anti-roll bar, the sway bar controls body roll when driving around a sharp bend. When damaged, the sway bar is known to produce a knocking or clunking sound which becomes obvious as you drive over bumps.
• Worn Control Arm Bushings:Car suspensions have a control arm that facilitates movement on rough terrains. They also come with bushings which can be polyurethane or rubber made. Designed to dwarf any noise that may be produced when the car goes over a bump, the bushing may also wear in the long run. Thus, an otherwise concealed noise will become more noticed as you drive uneven roads and bumps.

Getting started:

A professional mechanic will inspect the suspension system in your car and give a detailed report stating the cause of the problem and necessary repairs to get your car back in optimal operation.

The process:

The car will be raised and supported on jack stands. This will allow the tires to be removed and make it easier for the mechanic to carefully inspect your car’s suspension system. Where a sway bar link is present, the sway bar bushings will be inspected for wear or damage and replacements will be made if required.

The control arm bushings will similarly be inspected if problems are indicated and replaced as the case may be. Although loose caliper bolt is an unusual culprit, it is equally important to inspect the calipers in order to prevent any risk of braking problems in the future. If the calipers become loose, they may have worn over time and may also need to be replaced.

Why this service is important for your car:

The suspension system ensures that you drive comfortably and safely, especially when taking steep turns or braking. So it’s very important to seek professional help and have your car inspected when a banging noise is produced when driving over a bump. This will help to keep you and your passengers safe from potential loss of control when braking.
