A recent study found that about 68% of car owners are operating a vehicle that needs at least one repair–and these car owners don’t know what to do about it. Maintaining your vehicle is an important way to elongate your vehicle’s lifespan and keep long-term costs low. Undercarriage car parts are particularly important to monitor and replace as needed.

How can you tell if your car needs new undercarriage parts? We’ve got answers. Read on to learn five ways to determine that you need to look into buying new undercarriage car parts.

1. Your Engine Overheats

If your engine keeps overheating, it could mean that it’s time to get a new engine. First, however, take a look at your car’s undercarriage. If the undercarriage is blocked up with dirt and grime, it may be preventing the engine and transmission from distributing heat evenly when your car is running, leading to overheating problems.

2. Every Ride Seems Bumpy

Whether your car has struts or shock absorbers, a consistently bumpy ride may mean that it’s time to replace these parts. Although they function differently, both of these parts are designed to take on the bumpiness of the road and keep your car from vibrating or bouncing while you drive. Neither struts nor shocks are designed to last forever, and they will wear down over time.

3. You’ve Been Driving Over Road Salt

Road salt is great at making roads safer during the winter, but it does some serious damage to your car. As you drive through road salt, it tends to fly up and stick to your car’s undercarriage. If you don’t clean it off regularly, it can start to corrode the materials under your car.

4. You’ve Been Driving Over Rocks and Debris

If back roads are your go-to, you’re going to want to pay close attention to your car’s maintenance needs. Roads that are covered in rocks and other debris can wreak havoc on your car’s undercarriage. These hard objects may get caught in your tire’s traction and thrown up toward the undercarriage, knocking parts loose or cracking them.

5. You’re Noticing Visible Rusting

Whether you live in a high-humidity area or drive through the mud on the regular, any increase in moisture can lead to an increase in rust. Some cars have been treated with a water-resistant sealant to stave off rust build-up, but older models may need a touch-up. Keep an eye out for rust under your car and on the lower edge of your car’s body and make sure you don’t keep driving with rusty parts.

Your Car Isn’t the Only Vehicle You Need to Maintain

Cars aren’t the only vehicles that need regular maintenance. Tractors and other outdoor work vehicles are also prone to becoming damaged over time, and these repairs can become costly when not addressed right away. Stay on top of your John Deere undercarriage and replace parts as needed.

    the car is not that old and structural rust is almost impossible! If you want to protect your undercarriage simply wash the rusted parts with pressure washer or rust remover and use a protective sealant to avoid rust from appearing again!

    If I see a bolt that’s in the middle of the undercarriage that’s completely rusted, should I be concerned? There’s some surface rust in the middle of the undercarriage, but nowhere else that I could see. It’s a 2015 with about 90k miles.

    Thank you for the information on undercarriage parts. I never would have put the symptoms together with needing new parts. If an engine keeps overheating, you could need a new one. If the ride is too bumpy then you may need struts or shock absorbers. Even if you’ve been driving over road salt because it can cause damage to your car. A professional would be the next stop.
