Clunking noise from rear of car when going over bumps

When I going into turns, I hear popping sounds coming from the wheels, more so when I'm turning right then left. When I go over bumps I hear the same nose as above or a rattling sound like something is loose.

It sounds like you may be having an issue with one of your outer tie rods. The outer tie rods connect the power steering system to the wheels.

How to Diagnose Clunking Noise Bad Sway Bar Bushings in Your Car

These tie rods are ball joints but they are not the "ball joints" people commonly know just the same style joint, but different part. This ball can dry out and when it does it will make a popping noise when the ball rotates inside of its joint. Ball joints and tie rods are supposed to be greased once in a while to make sure that the steering linkage is lubricated.

If your steering has grease fittings, I would recommend greasing them regularly. If no fittings exist, I would recommend replacing the noisy part with a new one that includes a greasable joint. If you need help, a technician from YourMechanic can come to your home or office to replace the tie rods in your car. My car has miles. My car has an automatic transmission.

Vibration under acceleration could also be due to an Tire Pressure Tire pressure is measured and set when the tire is stone cold.Are you hearing rattling, clunking, or ringing noises coming from the front of your vehicle when going over a bump? If so, you likely have an issue with your suspension.

If left unattended, a suspension problem could cause significant damage to your vehicle, or worse — it could turn into a major safety hazard, endangering yourself and others on the road. The good news is that this is typically an issue that can be fixed by an experienced mechanic. When you bring in your car for an appointment, our automotive team will diagnose the problem and get it fixed the right way so that you can get back out on the road.

Most drivers can hear that something is wrong, but they are rarely sure of what exactly is the problem. While most modern vehicles tend to have relatively similar types of suspensions, there are many different implementation and component parts. For the untrained person, it can be difficult to figure out what is causing that annoying and potentially dangerous suspension rattle.

Certain types of noises tend to indicate certain types of problems. By listening to the problem, or your description of the sound, an experienced mechanic will often have a solid idea of what needs to be repaired or replaced. Though, to be certain, a visual inspection and subsequent testing will usually also be required.

For reference, some common sounds and problems include:. Notably, this sound often goes away when a vehicle reaches higher speeds. However, that does not mean that there is no problem. Alternatively, this sound could also indicate worn-out shock absorbers. Though, it could also suggest other issues, such as a damage to the suspension arm bearings. Ultimately, the only way to be sure that you have figured out the specific source of the problem in your vehicle is to bring it in to one of our experienced mechanics for an inspection.

There is no reason to wait, since the rattle is unlikely to go away on its own. By taking action now, you could save a lot of money in the long run. To set up an immediate appointment, please contact us today at We are friendly, professional, and always offer fair prices.

Oil Changes in Diesel Trucks December 23, Jun 6, If your car is making a knocking noise when driving over bumps, here are 5 components to look at before you bring it in to your mechanic. Before we dive into the diagnosis I need to let you know that not all noises are easy to find, some are hidden in components and are not visible. Struts and steering racks are a great example of hidden noises because the noise is an internal component noise.

Video and pictures tell a thousand words and I will be using them throughout this article. Steering Rack Noise. Steering rack end bushings can wear out and cause a knocking noise. If you suspect your steering rack is causing a knocking noise while driving on uneven road surfaces here is one way to check for play in the steering rack end bushings. Jack up the front of your vehicle, support it under the frame with jack stands, then grab the front tire at nine and three o'clock, give it a shake from side to side and have someone keep an eye on the inner tie rod, if you notice any unusual movement or you feel a knocking in the tire you may need to peal back the steering rack boot and check for damage, movement, or wear.

A sure sign of a rack end bushing failure is fluid leaking from the steering rack boot located at the inner tie rod. If you take a peak at the boot and you notice it wet with fluid, most likely the rack end seal is leaking because of the play or movement in the rack end bushing.

Broken Sway Bar Links. Broken sway bar links are very common in most vehicles because they take a lot of abuse and they are not very rugged. Sway bar links are small rod type linkage that have a nylon bushing ball socket on each end with a steel ball inserted into it that has a treaded end.

The sway bar link is built like a shoulder joint in the human body but with a ball and socket joint on each end. Worn Sway Bar Bushings. The small inexpensive bushings wear out over time and can cause a knocking noise while driving over small cracks and bumps in the pavement.

If you suspect this may be your problem and you would like to do a quick check, have a friend sit in the vehicle and close the door and listen for the noise. The person on the outside of the vehicle will rock the vehicle side to side like you were trying to roll it up on its side.

Grab the roof right above the drivers door and start rocking the vehicle, if the person inside the vehicle can hear the noise, your sway bar bushings will need to be replaced. Replacing sway bar bushings are an easy fix unless they are located on top of a subframe or hidden away, but a lot of the bushings and brackets are easy to get to and only require the removal of 2 bolts on each bracket.

Leaking Struts or Worn Strut Bushings. Worn or damaged struts can make a clunking or thumping noise when riding over bumps and large cracks in the road.

If you inspect the struts and you notice a lot of fluid and dirt collected on the strut like in the picture, its time to replace the struts, and again, I recommend in pairs. If money is tight you could just replace the leaking strut until you have the money to replace the second one, there is no rule stating that they need to be replace in pairs, I just recommend it for equal ride quality from both sides of the suspension. Strut bushings are a visual inspection. The strut will have to be removed to inspect the top bushings, but if the bottom of the strut has bushings, they should be easy to locate and inspect.

Shock absorbers are inspected the same way, most shock absorbers have a lower and upper bushing and are usually easier to remove than struts. Worn Ball Joints. There are several ball joints in a vehicle, some located in the front suspension and some in the rear suspension. The nylon socket is what usually wears out first and usually its because of the lack of lubrication or abuse potholes.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

It only takes a minute to sign up. I took it to my local garage and they told me the shockbreakers absorbers were busted. They have been fixed and the sound is now gone. Thanks for all the suggestions. Not necessarily a bad suspension.

I am not going to claim it is one specific thing because there are so many things it could be. There are several things that could be causing the knocking sound from the rear suspension.

My first guess was worn out bushings allowing metal-to-metal contact, broken sway bar end-links, or worn out shock mounts top or bottom. If you can, pop the rear tire off and inspect the suspension mounts for cracked rubber or worn out parts. If there are multiple knocks accompanied by excessive bouncing from the rear of the vehicle, then I would agree with user's comment that the shocks are likely blown out.

Freeman D. Freeman 1 1 gold badge 1 1 silver badge 7 7 bronze badges. Welcome to the site! How fast is 'regular speed'? Does it only knock once per speed bump?

I'd say its likely one or both of the shocks are bad. If you drive over a speed bump at an angle such that both wheels do not hit the bump at the same timeis it better or worse? And do you get one "thump" or two? Regular speed would be about mph, I usually just hit the bumps with both wheels. And it only bumps once or twice per speedbump. Freeman Jun 15 '16 at Try pushing down on the back end of the car and see if you can get it to make that noise.

If so, your shocks are probably shot. You could also see if you can get a friend to hop on the back bumper while you look underneath; if it's a missing sway bar bushing or other exposed suspension component you might be able to see what it is.

Active Oldest Votes.So I've been hearing clunking noise from my car lately. I went to multiple shops and they can't pinpoint the problem, that's why I diagnose it myself. So to start with, the noise comes on when I hit a bump more so when only the right side is hitting the bump or uneven roads.

I checked the shop if it was the exhaust system being too loose and it may have been, but they said it can not make that sound. I double checked the trunk by taking out the spare tires and checking the noise and it was still there. Finally, I folded the rear seats down and drove and the sound got louder, definitely noticeable even at high speeds. I checked online and they told me to check the suspension part that can be seen on the trunk. So I followed their advice and took a peak and I saw the part.

It looks stiff, but I can definitely hear the sound from that area. Hi there. However, before you schedule replacement of these components, you should have a professional mobile mechanic come to your location and complete a car is making a noise inspection. This will allow them to verify your diagnosis and suspicion so that the right repairs can be made.

Q: Clunking noise from the rear passenger side when going over uneven roads or bumps. Hi there! I don't know what it's called specifically to be honest. My car has miles.

Recommended Services. The statements expressed above are only for informational purposes and should be independently verified.

Please see our terms of service for more details.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.

5 Reasons Why a Car Makes a Knocking Noise When Driving Over Bumps

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. The jack stands should go under the jacking point locations. Then lower the vehicle onto the jack stands. For most modern cars, the jacking points for jack stands will be on the pinch weld just under the doors along the bottom of the car. Step 1: Grab a flashlight and look at the struts. See if the housing to the struts are dented or leaking oil.

Look at the bearing plate to see if there it is separating. Check the mounting bolts to the hub and ensure that they are tight using a wrench. Step 2: Grab a long pry bar.I can hear clunk sound from the rear part of the car when going over speed bumps, especially when the rear wheels just passed the bumps and hit the road. I do notice this sound sort of disappear when I adjust the air suspension to standard.

It also disappear when I'm passing the speed bump really slow. Does anyone have this same issue? I heard some people are having the same issue and they sent their MS to service center but end up told nothing wrong was found.

Engineer responds the clunk noise is coming from the design of the shock, functionally it has nothing wrong, but they are ordering a new shock that does not make that kind of noise for me.

How to Troubleshoot a Car That Makes Clunking Noises Over Bumps

I would ensure you have no loose items in the rear trunk, nooks and crannies which I'm sure you did. Check the rear-hatch door bumper stops. They screw up and down for height adjustment to support the hatch properly when closed. I've read that some have had issues with them not being adjusted properly. Call your service center. It could be a damaged control arm from hitting a pothole at a high speed. I suspect it has something to do with the air suspension.

Sounds like your suspension is hitting a hard limit stop when suspension is in a "softer" mode. Less damping force will allow more travel for a softer ride, but also allows suspension to bang up against the limit stop. I had a similar experience in the front. Service found a rock had become lodged in the wheel well in a rather unusual way. They removed the rock and the noise was gone I do notice that there is a sound like "some metal spring clicking" at the end of air suspension height raising process, which I think is not normal?

I'm a new Model S owner just over 2 weeks and while I don't have air suspension I was hearing a clunk when I turned into the parking garage at work the entry apron is uphill like a speed bump and it happened once going over a speed bump.

Definitely from the rear of the car just after my rear wheels transitioned from one surface to the other. This morning I went particularly slowly in that same spot and instead of a clunk I heard a dragging noise. I think one of those four front-to-back rails is bottoming out and causing the noise. Could that be happening with the OP's car, too, and have nothing to do with air suspension?

clunking noise from rear of car when going over bumps

I have never heard any dragging noise, and when I set suspension in standard mode I dont even hear the clunk. In either case, the car is driving fine, just the clunk sound. My MS is only miles, received it on June 6th latest update: dropped it off at service center today, both the technician and the engineer checked on it. Now I have peace in mind. Tropopause June 16, Check for loose lug-nuts.

Call the Service Center. Mathew98 June 16, I had a similar noise 2. For me, it was the liftgate not being adjusted correctly. Sorry, specifically, the hard rubber liftgate stoppers on the car where the gate lands.
