Sonata NF (2006-10) :: Suspension Noise - Creaking / Knocking Sound At The Left Rear
Mar 16, 2011
2006 Sonata 2.4 GLS. My car has done 60000 miles and has developed a creaking/knocking (metal on metal clunk) sound at the left rear. it is only noticeable at low speeds when accelerating and decelerating in stop start traffic.
It is not the shock as I have removed the shock and driven the car and the noise is still there, I have also looked at all the bushes and nothing is obvious. I have also checked tightness of all bolts/nuts.

I have pushed the back windshield, and haven't gotten a peep anywhere, so it's not that. It's coming from the outside, because it is so much louder driving slower with the windows down. It appears to be coming from the rear left of the car. It's a definite "creak," and not a "thunk." Sounds like creepy stairs being walked over repeatedly...I haven't investigated hard enough to really pin point the direct spot, but it would sound to me like it has something to do with the suspension in the back left. However, it's not any more prominent when I hit a bump than it is just accelerating or decelerating, so that also leads me away from it being a suspension issue. I know I should look further into it to locate the spot.

For the last year or so i have been annoyed severely by a clunking knocking sound from the rear (possibly passenger side) of the car. The noise occurs when there is torsion occurring or a sudden change of direction. I can go over a huge speed bump or pothole and not hear a thing yet the slightest change in direction or torsion will cause this extremely annoying heavy metal clunking knocking sound. I tightened every suspension system related screw in the rear of the car and the noise is still present.
The car is lowered on H&R springs (approx. 1.4 drop) so im wondering if maybe there is an additional stress that has been torturing the sway bar links for the last 3 years causing this noise. Or could it be the shocks (which are working properly)?

I have a 2009 Sonata Limited (4 cyl), and since the beginning of the summer, I have had a knocking/creaking type sound coming from both the front AND back of the car, which feels like is coming from underneath. I can feel it in the floor when it gets really hot, and therefore really bad. I hear it almost exclusively while accelerating or coming to a complete stop. When it gets really hot out, I can hear it very slightly while driving at slower speeds, but that's about it. Has no correlation to making turns, as would be the case with a tie rod.
I find it extremely strange that this is happening only in the heat. When it's cooler out, say below 80-85 degrees, there is no sound whatsoever. The car runs phenomenally otherwise, very quiet. Based on some stuff I've read, it seems like a suspension issue is a possibility? I live in a neighborhood with extremely poor roads, and actually live on a dirt road.

Sometime back I had posted that I was getting a minor creaking noise which occurred mainly when I was slowly making right hand turns. At that time the conjecture was it was caused by the mounting tabs (used when the car is assembled) on the rear suspension. The solution was to drop the suspension and file off the tabs. But then I saw at least one other post that said the cause was something else.
Well the minor annoyance has become a major annoyance since it has gotten progressively worse. Before I resort in taking ot to the dealer I'd like to see if I can figure it out and fix it myself. But before I tackle that job I thought I would ask others who had this problem what it turned out to be.

So I have the creaking noise on my front suspension. I'm going to replace, but I'm leaning toward not doing OEM ...

I have a 2007 Sonata with 99,000 miles on it. Around 4,000 miles ago I started getting a creaking noise in rear when I would slow down to a stop & then start again.
I have to drive the car for 15-20 minutes before the creaking starts. Once it starts it will happen for the entire ride. If I don't use the car for a couple of hours & then start it up again the noise goes away & doesn't return until I drive for 15-20 minutes.
After a 20 minute ride when I come to a stop the creaking happens each time you feather the breaks to a stop. The noise also occurs when you release the breaks when accelerating after stopping. It seams to coincide when the weight shifts.
Also I think I noticed that the noise is less pronounced when it is raining out.
I brought it to my local oil change guy for a state inspection & asked him to check the brakes & suspension. He said the suspension looked fine & the brakes were OK but the rotor had a hot spot that might be causing the noise. So, since the noise was driving me crazy I had the rear brakes done.
This didn't impact the noise at all. I brought it back to the same shop & spoke to the owner. They put the car on the lift & said that the rear suspension looked good & I could use rear shocks. So they replaced the shocks. This didn't impact the noise at all.
I drove it to my local Hyundai dealer. I drove it until the noise started occurring. They put it on the lift & found a loose bolt on the camber? and did an alignment. This didn't impact the noise at all.
I brought it back to the Hyundai dealer. They put it on the lift & couldn't find anything wrong with it. I then drove it for 20-25 minutes until the noise occurred & brought it back. Their mechanic drove in the car and heard the noise. We stopped in their lot and he crawled under the back of the car (not on the lift) had me rock the car up & down. He then said that the problem was the left rear upper control arm assembly. He said that he saw this at least one time on another Sonata.
What could cause a rear "suspension noise" that only occurs after you drive the car for 15-20 minutes? Also, the noise is more pronounced if you feather the brakes when you stop as opposed to just jamming them once to stop.

About a week ago I went over a dip in the road at about the speed limit and didn't realize how bad it was. Since then my rear end has been making a creaking/squeeking noise while driving or pushing on the car side to side. The struts seem to be ok, there is no bounce in the car. What this could be? I was thinking some sort of bushing somewhere?

My 06 Sonata LX 3.3 has me smiling except for two items, MPG, which I hope will improve after break-in, and a "k-thump" sound from the area of both rear tires. It occurs as I pass over fairly small bumps and ridges in the pavement, and remind me of the sound that is made by a bad shock. I took it to the dealer at 900 miles. They drove it and inspected the rear end and proclaimed all was OK. They claim it is caused by the low profile tires. I have never had low profile tires before, but it seems to me if that were the cause, the front tires would make the same sound, but they don't. The front end is sooo quiet. All tires have the recommended 30 PSI.

I just have a couple questions. First one I have a creaking in my front suspension when I go over bumps if I'm doing 50+mph it isn't heard anything slower you can hear it especially over speed bumps in parking lots. What could that be exactly? And also I'm looking to upgrade my headunit already got a single din but I'm wanting to replace the factory subwoofer. Can I replace it with a low power 8" aftermarket sub for better sound?

I have a 1997 Impreza wagon, 168K miles. There is a creaking noise from left lower suspension. Mechanic lubricated lower control arm bushings and front sway bar links. That lasted about 1/2 mile. It seems to go away when the temperature is high 70's or higher. Steering, etc., seem unaffected. When will this become fatal, if at all?

I'm in the market for an '09 Sonata 4cyl. I found a good looking one at a local Toyota dealership (supposed trade in). Unfortunately, the dealer claims there are no service records available...test drove it and heard noise coming from rear suspension when going over speed bumps. Dealer had tech look into it and said they lubed up the 'springs' and stabilizer/sway bar and now the noise is gone. Should I run away or take this thing in for an independent inspection, and if it checks out, buy it without the service records?

My car's rear suspension bushes are getting torn and are making squeaking noise in bumps. I am able to get bush for trailing arm and stabiliser bar. My dealer says that i have to replace the whole knuckle assembly as the bush for that part are not available separately. Is this true or the dealer is trying to earn some quick bucks?

I got my Sonata at 27k, its now at 76k and the cars been great although I had the following issues.
I've noticed sometimes when I startup and shift into reverse the car jerks a bit and its not a smooth transition. However other times the car is very fluid in switching gears. Should I take it in to have a look at it?
Also when I am turning onto a unleveled road (usually a higher road), I notice a creaking/knocking noise coming from the front of the car, also notice it when I reverse into a parking space sometimes.

We have an 07 Jeep Compass, 2.4L, 4WD. About 3 months ago we started to get a creaking/squeaking noise out of the rear suspension. First time I looked at it I found a lot of rust on the calipers and rotors, so new calipers, rotors and pads. Got quieter for a week or so, then it started again. Put the rear up on jack stands and pulled the wheels again. Used a 4' pipe to move the suspension up and done. Had a little bit of noise, but I could not pinpoint the source. Soaked all the bushings with light weight oil and put it back on the road.
A little better for a day or so, but still creaking. Had a problem with one of the new pads (the latest friction material, no abestos, no copper), so back on the stands and change the brakes again. Same thing, quieter for a day or so, then back to creaking. It does this at slow speeds in parking lots. Don't really hear it on the highway. Took it to a dealer for state inspection and told them find the squeak. Claimed they could not hear it.
My daughter drove the mechanic around, no noise. 5 miles after it left the dealer it is back. There is a TSB for parking brake cables with a boot failure. Checked our over the weekend and boots are good, cables are not rubbing. It seems if you fully extend the suspension by jacking it up, that makes it better for a day or so, then its back. Sprayed every joint with Lithium grease last time.

2011 GLS 2.4L auto, 40K, out of warranty
There is a loud groaning/creaking noise coming from the front suspension area. At low speeds, this noise dominates all other noises and is directly related to hitting the gas or pressing the brakes, which produces a forward or backward force on the front suspension and chassis. I can sometimes hear it briefly just by pushing against the parked car.
My hope is that I can just tighten up some bolts and make this go away, but other posts suggest it may be struts, stabilizer links or other non-obvious sources.

I have some noise coming from the front suspension. It is a popping/sorta creaking noise. I hear it mostly when turning, but sometimes while going straight. It is not a grinding sound, nor is it a high pitched sound. I took it to my mechanic, but they drove it and could not replicate the noise. They inspected the front end, and said everything looked fine. But I still hear the noise. The car has a little over 40k miles on it. No problems with the tires...no irregular wear, and no wandering. I looked at the front end, and didn't find anything obvious. I cannot replicate the noise just by pushing on the fenders up and down.

This auto has 143,000 miles on it. I recenty noticed a creaking noise from the left front when accelerating from a dead stop. The shop I have used for 15 years said that the motor mounts are deteriorating and should be replaced. I trust the guy but would like to avoid the $1,400 repair. There are no symptoms other than the ocassional noise.
What is the downside of ignoring his recommendation? What other symptoms can I expect if I delay the repair? Can this be a serious safety issue? I plan to keep the car for another two years unless I bite the dust first or the engine falls out.
