Category: Car makes creaking noise when going over bumps

Ever since I had a tire blow out on the highway almost 4 months ago, I have noticed there is a creaking noise that comes from underneath the car at times. Kind of sounds like a ship creaking or something. Tried to get the mechanic to listen to it,he drove the car around the block but all heard was the convertible top hooks rattling.

But my girlfriend heard it the other night and she said that wasnt normal and I need to bet it checked out. The mechanic said no. I had a car that the axle broke while I was driving it down the street…thank God I was going really slow at the time.

Anyway, do you have any idea what could be making that noise? I am always worrying over this dang noise. You might have bad struts up front, which would bottom out on bumps to make a loud thunk!

There might be some creaking sound associated with that during average winter driving. You need to tell us WHEN the vehicle makes this noise…what is it associated with? It has to occur in conjunction with something… WHen you turn the wheel?

When you stop? When you accelerate? When you smile? Need the infoooo. When I am driving…mostly slowly only,sometimes when I step on the brake and slowdown and sometimes when i turn the steering wheel. If you can make the noise by bouncing on the bumper, or turning the wheel while parked, you can find the noise.

Take a rubber hose and have a friend make the noise while you chase it down. Sound like fun? Or you can find a mechanic with a chassis ear. It has clamps that you can put on various suspensions and steering components to listen to different channels?

More than likely the blown tire had nothing to do with this problem. Since it happened about 4 months ago this would coincide with the onset of wintertime cold weather. The most common cause of creaking noises in the suspension are sway bar bushings. With age and cold weather the rubber hardens and the sway bar tries to bind on the rubber.

This will cause creaks, groans, squeaks, etc. This is also a very common problem and is generally solved by lubricating the sway bar bushings with a silicone based grease or by replacing them.

Try pushing down real hard on the top of each front fender and note if you can hear the noise. Other less likely causes of this problem would be a control arm through bolt, dry tie rod end or ball joint ball socket, strut coil spring pad, etc. ComfortEagle July 6,am 5. My guess would be a sway bar link or bushing.If you drive over bumps and hear a clunking sound, there is a good possibility that something important is wrong with your car.

Frequently, the suspension system is at fault when you hear a clunk sound. When it comes to diagnosing a clunking noise when driving over bumps, a road test is required to determine the sound.

Before you take the vehicle on a road test, you need to walk around the vehicle to ensure that there is nothing falling off the vehicle. Look underneath to see if any parts to the vehicle has broken off. If something is broken on the vehicle that is safety related, you will need to address the item first before conducting a road test.

Also, be sure to check the tire pressure. This keeps the vehicle from overheating the tires and allows you to do a correct test. Step 1: Push down on the front and rear of the vehicle. This will check to see if the strut shocks are performing correctly. When the strut housing becomes dented, the strut shock will pop in and out of the strut tube. Step 2: Start the engine. Turn the wheels from lock to lock going from right to left.

This will check to see if the bearing plates will make a clicking or popping noise while the vehicle is stationary. Step 3: Drive the vehicle around the block. Make turns where you can turn the steering wheel all the way in a direction. Listen for any clicking or popping sounds. The struts are designed to turn with the wheels as the struts have a mounting surface for the wheel hub. While checking the struts for sounds, feel the steering wheel for any movement as if the mounting bolts to the wheel hubs could be loose making the wheels move in and out of alignment.

Step 4: Drive the vehicle over bumps or potholes. This checks the condition of the strut shaft and if there are any broken internal parts or dented shell. Step 1: Park your vehicle on a flat, hard surface.

Make sure that the transmission is in park for automatics or in 1st gear for manuals. Step 2: Place wheel chocks around the rear tires that will be remaining on the ground. Engage the parking brake to the lock the rear tires from moving. Step 3: Raise the vehicle. Using a floor jack that is recommended for the weight of the vehicle, lift under the vehicle at its specified jacking points until the wheels are completely off the ground.

Step 4: Place the jack stands.

car makes creaking noise when going over bumps

Having a squeaky suspension can be one of the most frustrating problems to have in any vehicle. Every time you go over even the smallest bump or make a turn, you have to deal with the squeaks and creaks of your suspension.

Squeaky suspensions are not just embarrassing, they can also be an indication that there is a big problem with your suspension. Besides the annoying noise, a broken suspension system in your vehicle can increase the likelihood of rollovers, make it difficult to control your vehicle in corners and can increase your stopping distance in an emergency. Suspension issues can also cause your steering geometry to be incorrect which can lead to increased tire wear and difficulty negotiating turns.

A squeaky suspension system is not just embarrassing with those squeaking noises and grinding noises, but it is also dangerous and can be extremely difficult to diagnose and fix.

You also have a shock absorber by each wheel and in most cases a sway bar or anti-roll bar both in the front and in the back. Each one of these components have a joint on each end that could be the source of your noise. There are three types of joints commonly used in your suspension components.

Ball joints are used when the joint must be able to move in multiple plans such as rotating and moving up and down. For example, the joint at the end of your lower control arm that connects to the steering knuckle needs to move up and down as the spring compresses, but also turn as you turn the steering wheel. Ball joints are much like your shoulder or hip joint where a stainless steel ball fits in a Teflon cup and provides the range of motion and rigidity needed.

Ball joints sometimes have grease fittings in the cup and a rubber boot containing the grease.

Why is my Car Squeaking when I Go over Bumps - Possible Causes

If the boot rips these joints can start to make squeaks when you turn. If you find a ball joint with a torn boot, consider replacing it. Bushings are used if the joint only needs to move in one direction, such as up and down or side to side. Bushings are the most common joints in your suspension system and also the most likely to case a squeaky suspension. Bushings are basically rubber sleeves that go between the frame of your vehicle and the suspension component which allows the suspension component to rotate.

Bushings can squeak if the rubber becomes torn or even dried out or if the suspension component starts to rotate inside the metal sleeve inside the bushing due to incorrect torque or a broken bushing. Worn out bushings cause more movement which in return causes those squeaking noises as well as incorrect suspension geometry.

If you suspect a squeaking bushing, try spraying a small amount of lubricant on the bushings to see if the noise goes away temporarily. If it does, consider replacing the bushing. For an even quieter ride, consider using polyurethane bushings. The last type of joint used is a simple rubber mount. These type of joints are used if only a small amount of motion is required and are much like engine or transmission mounts.

These types of mounts are often used on the rear side of lower control arms.One clue the suspension system in your car isn't working properly is an uneven wear pattern on your tires.

4 noises from your car's suspension that could mean trouble

Around the shock absorber, is a coil spring called a strut. The strut adds to the shock dissipation. These parts work together to deliver a smoother ride and to keep your tires firmly on the road, which is why maintaining the proper tire pressure is also critical. Tires are part of the suspension system, too. If they're not and you notice irregular tread wear patterns, there's a chance you'll have to replace certain suspension parts and wind up buying new tires.

I have the same issue.

I'm assuming just needs to be relubed. Definitely sounds bushing related. I have 9K miles on my 3 and the ride isn't quite as smooth, the car isn't quite as quiet and the creaks are getting progressively louder.

I have a service appointment tomorrow, asking Tesla to ensure the car is as tight as it should be. I have noticed its MUCH worse later in the day after the car has sat in the sun. As temps get higher here in SoCal, it becomes almost unbearable. On my way into work in the morning, there is almost no creaking, on my way home after it has sat in the sun all day its agonizing.

I was able to reproduce the creak by pushing down on the fender of the car with it parked and took a video. During actual driving, its much worse and louder. This is just what we were able to get out of it by pushing down on the fender.

Please give it a watch and let me know your thoughts. Can't watch the video now but sounds like a bushing. You can try reclocking it or having Tesla replace. I can't imagine there is anything to lube down there besides the sway bar bushings, which shouldn't have to be lubed anyway.

I started to hear these creaks as well, starting in December or so. I mainly hear it on the driver's side when going over small bumps or even rough patches of road. Hope it's something minor. I've been reluctant to go in to the service center.

Don't really want a Model S loaner if it is a bigger problem.Eddie spent 35 years in the automotive business with Honda. If you own a car, it probably makes noises you can't identify, but would love to fix.

Car noises are not just annoying: sometimes they are a warning sign, like the calm before a storm. Here are the four car noises customers most commonly complain about. Sometimes noises are hard to identify, because a noise travels throughout the vehicle and it is hard to pinpoint where it's coming from. But with a trained ear and some insight, we should be able to figure out what is causing the noise in your car and what you can do to fix it. If your car is making a clicking noise when turning, it is likely you have an outer CV joint constant velocity joint that has failed because of a torn boot or old age, most likely a torn boot.

Without going into too much detail about what a CV joint is, I will just give you a basic idea of its function and why it might have failed. A CV joint is a set of ball bearings at the inner and outer ends of an axle.

Eventually it will split open and allow specks of dirt and debris to enter the joint. Once foreign matter mixes with the grease, the damage begins, and it is only a matter of time before the CV joint starts to make a clicking noise when turning.

This clicking noise while turning will start out faint, but gradually it will become noticeable and eventually very loud. The only way to fix this condition is to replace either the whole axle assembly or the outer CV joint. Water pump noises are very difficult to diagnose, because the water pump is generally buried deep in the motor, and the noise will resonate through the engine making it difficult to identify.

The water pump on your engine is a thick metal casting containing a pulley, pump fins a palm-sized propeller to push the water alongand a bearing set.

When a water pump fails, the noise is usually caused by damage to the bearings. The video below is a great example of what a noisy water pump sounds like.

If you suspect your water pump is the culprit for the noise in your car, try to locate the water pump on the engine. The only fix for a noisy water pump is to replace it. If it is nearly time for a routine timing belt replacement every 60, tomiles or so depending on the caryou might want to have that done at the same time as the water pump, because timing belt service is one of the rare occasions when a water pump is easy to get to.

In the video below, the mechanic uses a screwdriver like a stethoscope, pressing it against the hub of a wheel to listen to a wheel bearing noise. Engine belts can create a loud, high-pitched squeak or squeal that will drive you and your neighbors crazy. Some engine belts only squeak after you go through a large puddle or if there is heavy moisture in the air, and others squeak constantly.

If your engine belts squeak only when damp, you probably only need to have the belts adjusted. If your belts squeak constantly, they may be dry, cracked, or loose, and probably need to be replaced. Keep in mind that this spray will not fix anything permanently. It is, however, a great tool for diagnosing the noise and finding out which belt the noise is coming from.When you go over bumps on the road, you may sometimes hear a squeaking noise coming from either side of your car.

Equally, you might hear a squeak from underneath in the chassis. This noise is not only embarrassing, as everyone around you turns their head to see your car, but can be a sign that there is something seriously wrong. This can lead to damage to the vehicle or even result in an accident.

Read this oneHOWTO article if you want to know the reason why this problem happens and find out why your car squeaks when you go over bumps.

A squeaky sound may be caused by the connecting ball joint or rubber bushing being worn out. Ball joints are connections in which a metal ball is trapped inside in a cup lubricated with grease. Most ball joints are not lubricated externally. If the grease gets old or leaks out, the joints can start squeaking. Bushings are designed to prevent individual parts from vibrating and causing damage.

Rubber bushings are common on a car's suspension. If they are faulty, broken or non-existent, then the vibrations may cause damage which leads to squeaking. Most rubber bushings are not lubricated and have to work dry only. Over time, the rubber shrinks, cracks or dries and starts squeaking whenever the suspension moves. Checking your bushings regularly is helpful in preventing damage further down the line.

Another possible cause is that another part of your suspension is either damaged or broken, which is a more serious problem than the first. The suspension is composed by many smaller parts that are connected by axles, making them difficult to access. If any of these parts are faulty, it can lead to squeaking sounds coming from the suspension. Faulty suspension is why the car might squeak when going over bumps. The suspension is there to stop shocks damaging the vehicle when going over bumps or uneven ground.

If they are faulty, the bumps will cause issues. Shock absorbers are part of the car's suspension. If they do not work, they can lead to squeaking. The problem will depend on the type of absorber.

If they are hydraulic, then they may have air problems, oil leakage or another issue. Spring absorbers may have rusted or been broken in a high impact. Isolating the absorber and confirming the problem is vital. If you want to know more, read up on how to replace a shock absorber in your car. While the most likely problem when your car squeaks going over bumps is to due with suspension, there are other issues. The problem might actually be close to where you are seated.

The steering wheel control arm might be loose or faulty. When you go over a bumpthe force causes the wheel to squeak. You can try to listen closer to the steering wheel, although it can be difficult to know where the squeak is coming from.

It is very difficult to identify which bushing or ball joint is causing the squeaking noise. Most of the time, when the vehicle is still, the suspension does not move the way it does when it is running. This makes it much harder to identify the part that is causing the problem.
