Loose MufflersA common problem that affects older cars is a loose muffler. If you’re not so knowledgeable about cars, you might not know how to prevent this or even how to recognize the signs when the muffler is loose. Here’s what you need to know about loose mufflers and how you can fix them.

How a Muffler Comes Loose

Generally, there are three reasons why mufflers come loose: a bad bracket, connector, or rubber hanger. While these components start out strong, they can eventually corrode and weaken, allowing the muffler to shift around and rattle when you’re on the road. In particular, salt, debris, excessive heat, and excessive moisture are all catalysts that can cause rust, which is the primary factor in corrosion. To protect your muffler, avoid driving your car in bad weather and store it in a garage when not in use.

Broken Muffler & Bad Muffler Symptoms

When you’re having muffler issues, the No. 1 thing you’ll notice is loud noises when you rev your engine. Usually, a muffler works as a car silencer and helps to quiet the sound coming out of your exhaust. When the muffler isn’t functioning or the exhaust pipe comes loose from the muffler, these sounds will escape and make you sound like a monster rolling down the street. While some people enjoy this raucous sound, it’s a nuisance for others within hearing distance.

You’ll also probably notice a bad smell coming from the back of your vehicle. In addition to dampening sound, the muffler funnels exhaust fumes out and away from your car. With a broken muffler, these fumes will linger and pollute the air inside your vehicle.

The least noticeable symptom is a decrease in your miles per gallon. If you track how many miles you get per tank, you’ll quickly notice a slump when your muffler is on the fritz.

How to Fix a Hanging Muffler

You can still drive if your muffler is loose, but it isn’t the best idea. Because a loose muffler might hang lower than normal, you risk hitting it on road bumps or railroad tracks. If the corrosion is extremely severe, it might even fall off completely while you’re driving. Plus, there’s a real risk of carbon monoxide poisoning if too many fumes enter your vehicle.

The best solution for a broken muffler is to visit your mechanic and have them diagnose the problem and perform a muffler fix. However, if you’re short on cash, you may be wondering how to fix a muffler yourself. you can try a DIY remedy to get the problem at bay for the moment. Follow these steps:

  • Crawl under your car.
  • Tighten any loose bolts holding the muffler in place.
  • Lift the muffler up to where it should be and wrap a steel zip tie around it and the frame of your vehicle.
  • This should keep it in place until you have the funds for a professional repair.
