Welcome all. Today we will discuss about why car makes noise over bumps. If you’ve ever driven down an old street with speed bumps in the road and felt your car actually hit the bumps, you already know how annoying these obstructions can be to drivers. However, there are many benefits of speed bumps in residential areas or streets near schools or hospitals, so if they are installed correctly they can help maintain safe driving conditions even when traffic is particularly heavy, such as at rush hour or right before and after school hours. With that said, here are a few tips on how to avoid hitting speed bumps if you’re looking forward to using your vehicle more often.

Look for the bumps

Check your tires to see if they are low in air pressure or if they have a puncture, which can make a car feel as though it is hitting bumps even when it is not. - Drive more slowly over the bump instead of braking suddenly, which can result in a front end clunking noise when going over the bump or a low pitch rotating sound while driving. Stopping abruptly could cause an issue that is related to the strut mount and allow them time to cool before starting again. It might be wise to take some responsibility and find out what might be causing these noises yourself! Make sure your brake fluid levels are full and replace any leaking brake hoses. 

It's important to keep up with routine maintenance on your vehicle so you can enjoy driving without worrying about unexpected problems.

Approach them at an angle

If you've noticed that your car is feeling bumpier lately, it's likely because the front end is making a low pitch rotating sound while driving over a bump. This usually occurs when the strut mount noise over bumps or front end clunking noise when going over bumps are no longer doing their job and your suspension is worn out from all of the wear and tear on your tires, which makes them more prone to going flat, too.

Since your tires are wearing out, they're also becoming less effective at absorbing rough patches in the road, which puts extra stress on your car's struts, or shock absorbers. Fortunately, there is a relatively easy fix to smooth things out and avoid that low pitch rotating sound while driving over a bump.

Don't hit them too hard

Speed bumps are designed to slow vehicles down in densely populated areas, and if you're careful, they're not a big deal. If you hit them too hard, though, it can be a big problem for your car and you'll need to get some help from your mechanic. If your car is making strut mount noise over the bump or front end clunking noise when going over the bump (or low pitch rotating sound while driving), then it's time to go see the mechanic before something gets out of hand!

Avoid them if possible

Speed bumps are difficult to avoid, but if you know where they're at, it's not too difficult. Try to slow down going over the bump, and if you hear a low-pitched rotating sound while driving, your strut mounts are worn out and need to be replaced. If you hear a front end clunking noise when going over the bump, try replacing your shocks or struts that mount at the front of your vehicle. You may also want to consider replacing the springs in the rear, which could cause an annoying rattling noise. 

If you hear a low pitch rotating sound while driving on bumps, you may want to replace your strut mounts as they are worn out and broken. A low pitched rotating sound is usually heard when driving over bumps. If you notice the front end clunking noise when going over the bump, you may want to check your shock and strut mounts; they are probably broken. The low pitched rotating sound usually indicates that there is wear and tear on both your suspension parts, including struts and brakes.
