Whether the engine is humming or tires are squeaking to a stop, cars make a lot of noise. Sometimes that clanking you hear while driving may simply be a stick stuck in your wheel. However, sometimes vehicle noises are an indication of a more serious problem at hand. If these sounds are ignored, then you could be facing dire car troubles when you are on the road. In order to determine what car sounds need attention, the experts at DriversServices.org have compiled a list of potentially dangerous vehicle sounds to watch out for while you drive.
If you hear a constant hissing sound while you are driving, you probably have a leak in one of your engine systems. Typically, hissing sounds arise from a leak in the cooling system or vacuum line. If your cooling system is leaking, your car could overheat. If your vacuum line is leaking, your car’s drivability and fuel-economy may be at risk. Either way, DriversServices.org recommends you see a mechanic as soon as possible.
If your car clunks when you drive, something is either loose or misaligned. The first step to addressing this problem is to identify where the clunking is coming from. If you hear it while you are driving and it gets faster while you drive, then the problem lies in your axle or in your CV joint. If you hear the clunking while you are stopped and the engine is running, then it is probably a transmission or engine problem. You can check this by having someone rev the engine while you inspect it and its accessories. If the clunking sound resurfaces in another circumstance, then it is most likely a suspension problem. Suspension repair costs can range from $300 to $5,000, so the experts at DriversServices.org recommend you get this potential problem fixed before the suspension needs replacing.
Squealing sounds from under the hood likely indicate a problem with the serpentine belt. Usually, the belt will begin to squeal with age and wear, or if the tensioner is failing. Luckily, the serpentine belt is inexpensive to replace, so the team at DriversServices.org urges you to get this item replaced before the belt ends up snapping while you are driving.
Usually, screeching or groaning occurs when you are braking, which is a clear sign of brake pad wear and tear. The team at DriversServices.org recommends you replace your brake pads every 50,000 miles, depending on how much and where you drive. This regular maintenance costs about $100 on average. If you allow your brake pads to deteriorate, then this will result in damaged rotors, which are much more costly to replace.
Loud hammering sounds while you are driving are usually the result of failure in the rod bearings of your engine. This is a serious problem that needs to be handled by a professional right away. If the rod bearings blow, then your engine will completely fail, which means you will most likely have to get a new vehicle.
