Sonata NF (2006-10) :: Rear Suspension K-thunk Sound When Pass Over Ridges In Pavement
Oct 2, 2005
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.

Alright so my 06 is at about 102,xxx right now and has given me no major issues (knock on wood) besides this stupid noise that I cant pin point to fix. So far I've narrowed it down to this, sounds like its coming from the right rear and usually only happens when I am slowing down and or braking. Ive also taken note that it only happens when its really hot outside , all signs have been pointing to the rotors and brakes but i need some thoughts/opinions on what else it could be before i shell out almost $200 to get my brakes fixed. Here are some more details about the car
Rear pads replaced sometime last year they still have meat on them but i did not replace rotors nor did i get them turned.
I am sure that the noise is coming from the rear, ive been half way in the trunk while my buddy drove and i hear it coming from right rear.
Shocks have been replaced (noise was occurring before replacing them)
Nothing seems loose everything seems to be tightened down right.
Tires are brand new (noise was there before getting tires and after)
Mufflers are secured normal wiggle mounts look good.
Emergency Shoes have never been replaced but look ok.
Wheel hub looked great when i took it apart (Looks new doubt its that)
It happens when I am braking from 35mph below or sometimes 0 to 35 40mph rolling no braking then it goes away.

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)?

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 FK Highsport coilover and have had them installed for a little under a year. After about 6 months I started hearing this thunk sound coming from the front right suspension. The sound only happens when I turn right, and when I turn from right to straight. I haven't had the time to pull it apart yet. I was thinking that it might be a binding spring.

I have a 2002 accord 4-cyl with a 5-speed with 89,xxx miles. Just a few months ago, I noticed a clunking sound coming from the front suspension when I go over certain bumps. "Certain" bumps are usually wavy pavement or dips (not wide dips, but short/concise ones), and sometimes certain speed bumps. Sometimes the sound happens regardless of the types of bumps though, but the aforementioned ones usually bring the noise quite consistently. The sound hasn't really gotten worse, but it hasn't been getting better either.
A while back when I had my timing belt done, the mechanic stated that one (or more) of my engine mounts were worn. Is it possible one or more of my engine mounts is the source of this issue (from the engine "rattling" around in the compartment. I'm not sure if that's even possible, just a hypothesis) or is it purely suspension. PS. The sound isn't quite a sharp metal on metal sound. Its more of a "thump" or "clunk" coming from the front end (left or right) as if its bottoming out or a bushing or spacer has worn off. Its just loud enough to drive me crazy, and sometimes I can feel it through the floor.

When I drive over quick choppy bumps in pavement I get a rattle in the rear of the suspension, but only when the bump is on one side. When the bump is long and activates both rear wheels, like a speed bump or a large road crack I don't get the rattle.
The sound seems to be worse on the right side and I can't really figure it out. Anything specific I should look out for?

I got my coilovers installed, love em....but now I have a clunking sound. Oddly enough it happens when I'm on flat pavement...not when I'm going over bumps.

So I lowered my car, and I really don't have any issues. Running 19 inch wheels and I upgraded all suspension components.
Shocks, Struts, Springs and before I did that, I had new adjustable ball joints installed. I am still having some small vibration once I get around 70mph. Also, I have that infamous THUNK** when I hit a big dip. So I looked for the adjustable control arms and they are about $345 and kspec nor Sharkracing has them in plus I am not even wanting to spend that anymore.
I am trying to determine the small vibration as I replaced 3 of the 4 ball joints with that being the 2 upper and left lower and did not replace the right lower because the mechanic said I did not need to as it was in good shape. I am wondering if that is the cause of my slight vibration or if it is just the road.
Onto the clunking, I think I am going to just order Moog upper control arms and replace them myself. It sucks to go backwards from adjustable ones but seems like no one here on the board has had any alignment issues with running regular control arms with the bigger rims. This was my main concern. So I am going to order them this morning.
Now what I am not too up on is sway bar bushings. Can these cause vibration and how hard are they to fix? Just read that you can tell if these are going bad by turning left of right quickly. Guess I don't need these yet.

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 own a 2005 Lincoln LS V8 with 111,000 miles on it.
Recently the Advance Trac-traction control light will come on for no reason. When I push the console button-to disengage the Advance trac-nothing happens.
However, if I shut the car off, and restart it, the light goes out. Most often the light will stay out for a few days. Once in a while it will light up in a mile or so. Again, this is intermittent.
I did hear a big thunking sound from the rear end the other evening upon a hard acceleration. I do not know if this is related.
Both the loud thunk-almost like someone has hit the back of the car- and the advance trac light have occurred before; never together though. What may be causing the advance trac light to act this way? And what the thunk is from? !!

So I know the 2013 GS (or many GS in general) have had complaints of squeaks and rattles. My GS has a couple but are very minor and only occasional.
I do have one noise that seems unusual though. When I am driving and drive over moderate bumps in the road, I hear a muffled clunk or thunk type of noise only from the rear passenger area and never anywhere else.
My car is a stock CPO 2013 F sport and not lowered or anything. Stock rims and tires. The shock does not seem to be leaking.
The noise happens regardless of if I am in regular or sport+ modes. Was going to mention it to the dealer at my next oil change and door trim replacement appointment I need to make Ina couple months.

My 2009 Sonata has developed a 'rubbing' sound that seems to be coming from the right rear wheel. The brakes are new, the rotors are fine, there are no marks on the tire or wheel. This sound only shows up when I apply the brakes and generally at slowing speeds. If I press the brake pedal down hard the sound doesn't emit. We have checked suspension, brakes, rotors, tire and wheel.

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.

Spring has arrived and the whoop-de-dues are reminding me that the suspension in my 2013 passat tdi is rather soft. it rides great on a smooth highway but i would be curious if there is a way to change the suspension so that it 'floats' less on uneven pavement and in tight turns?
My goals would be:
1. float less on uneven pavement
2. track flatter and smoother in tight turns at speed
3. maintain highway comfort or dam close to it (99% of my driving)
4. remain at stock height (i am not lowering this car up here!)
It may not be possible to achieve all of this but at this point i do not know what is possible or what the pros and cons are of any suggested changes. A quick search of 'tdi suspension' on vwvortex gave me a few hits but mostly for golf and jettas.

Have just leased 2008 pasat 2.0l turbo. Great engine but suspension has loud rumbles /noise on uneven pavement. Have lowered tire pressure to 30 . suspension noise still persists. only have 1500 miles. dealer says that everything is still to factory spec.

Since Ive got my 2010 Tiguan 2.0 TSI, I hear a creaking noise coming from the front right suspension when riding over uneven pavement. The dealer said it is a common known problem from many Tiguans caused by the engine mount and that VW recommends the change of that part.
The new engine mount is slightly different from the one that is installed in my car. I am still waiting for the part to arrive and to be changed. Meanwhile, I spoke with another 2010 Tiguan owner, here in Brazil, whose car has already received the new part.
He said that the creaking noise has gone but now he feels more vibration coming from the engine and a kind of "diesel-engine-sound" when accelerating... Location of the engine mount: [URL] ....
The "old" engine mount bears the code:
5N0 199 262 G
5AY CN
M086
09/03/27
[URL] ....
The "new" engine mount bears the code:
5N0 199 262 E
5AY CN
M082
09/03/10
[URL] ....
I assume that the first number is the part number, the last is the manufacturing date and the others are either car model or manufacturer code or anything else. Note that the part number is the same, except by the letter suffix: "G" in the "old" one and "E" in the "new" part. Well, the suffix designation does not make sense for an evolutionary design...
My questions are:
1) Is it a new design or is it a roll back to an older part that does not cause that problem although it was probably modified due to another issue?
2) Is this part number specific for 2.0 TSI engine or is it the same for other engines (petrol/diesel)?
3) Which engine mount have you got on your cars?

I am looking to reduce the weight on my rear suspension. I have H&R springs and I rub on bumps. Fenders need to be rolled but the inside of the tire is being rubbed on the strut housing. My subwoofer box doesnt work for my situation either, saw a thread already about this but he was recommended coils. I rather not go that route. Ive already removed the rear seats(foldable part, bench is still there) ...

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.

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?
