Your exhaust system takes quite a beating while it is suspended under your car. Think about it - you're traveling at high speeds, over bumps, through unfavorable road conditions, and much more. If it wasn't properly affixed to the car, then you can bet it would fall off, break, crack, and wear down awfully fast. Not only that, but think about your exhaust pipe bouncing all around, vibrating, and making all kinds of sounds. That's what you and your passengers would have to listen to.
This is where the exhaust system hanger comes in very handy. These are rubber mounts and they securely fasten the exhaust pipe to your vehicle's undercarriage. Thanks to the hangers you won’t have to worry about any of the problems above, that is until they fail, which can happen. It's not likely the exhaust hanger will be able to last the lifetime of your vehicle. Instead they wear down over time, and then need replacing. It's best to have it inspected on a fairly regular basis just to be sure you catch it when it happens.
Should your exhaust system hanger fail there are a few telling signs you can watch for. Let’s take a look at these signs that likely mean your exhaust system hanger has reached the end of its lifespan.
One of the most telling signs is if you can see your exhaust pipe or muffler hanging low beneath your car. This definitely shouldn't be the case, and usually means the exhaust system hanger has broken and needs replacing.
Some vehicles have more than one tailpipe. Take a look at each of them and compare them. Are they level? Is one hanging down lower than the other? If there is one that seems to be lower, that one likely needs attention where the exhaust system hanger is concerned.
Keep in mind that this is the kind of replacement job you want to do right away so that you don't end up damaging other parts of your car.
The exhaust system hanger ensures that your exhaust system stays where it is meant to be, and it is able to handle the bumps and jars on the road. If you’re experiencing any of the above mentioned symptoms and suspect your exhaust system hanger is in need of replacement, get a diagnostic or book an exhaust system hanger replacement service with a professional mechanic.
