Sonata NF (2006-10) :: Small Vibration Once Get Around 70 Mph / Thunk When Hit A Big Dip
Jun 17, 2013
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.

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.

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.

For a few months, I smell coolant when I get into the car. I thought it was the food left behind. Finally this morning I saw a small puddle of coolant on driveway. green color as we had a snow/ice storm. Lost about 3/4 inch coolant in expansion tank. still about low on cold freezing day.
I searched through this forum, not a common thing for the heater core.. There were cases about freezer plug not tight..hose clamp not tight. etc
My question is that where is the freezer plug? Any easier way to get to the the heater core.? without taking the whole dash out?
I4 2.4 ....

I smelled antifreeze when walking by my fiances Sonata, so I popped the hood and saw there was a small leak from the upper radiator hose, where it meets the thermostat housing. I adjusted the stock clamp, but the leak was much worse.
I swapped it out for new clamp that you can tighten, and all is well again. But, what I noticed when I had it off was that the metal neck of the housing was really corroded. Only 15,000 on the car, so I was surprised to see that the corrosion on the metal had already built up causing the leak (pushing the hose away from the housing). I scraped and scuffed to get it clean again, but just wanted to give you all the heads up in case you notice a leak in the same area. The antifreeze tested good and is really clean.

I seem to be having a front end noise that only started up a few weeks ago.. The suspension doesn't make any noise over small bumps, only for larger ones. It makes the most noise when pulling into a drive way or something with a steeper grade from a flat street.
The noise I am experiencing sounds more like a scraping. It's not the power steering pump and it's not the brakes. Also, nothing is under the car that would cause this type of noise. It doesn't click or sound like a CV joint, I know what that sounds like. It also has no affect on any other performance of the car. I have tried jumping/pushing down on the car and it cannot seemed to be re-produced. Where I can start looking?

My 2007 Sonata continues to throw a P0456 code, small evap leak detected, gas cap is tight, getting ready to check the evap hoses. The question I have is the evap system covered under the emissions warranty at all ?

I bought a 09 Sonata GLS in July, really nice other than dash noise, what has been described as crackle. Briefly, my sonata is makes crackling noise going over small bumps, more pronounced in colder temp. I have taken it in to the dealer 4 times, problem still persist. According to the dealer, Hyundai regional office knows of my problem, and there is no fix for it at this time. I just bought the vehicle and I am suppose to live with it?????

I have a 2007 Sonata Ltd (63000 miles) and had a clunk in the front suspension. I had the front upper control arms replaced (which were visually badly worn) and that fixed the problem. But now, a several months later another similar clunking noise has developed when I go over those small speed bumps in parking lots.

I've got my 2013 sonata and have noticed over the past couple weeks that after the car has sat for a while and I shift out of park that it makes a thunk/shifting sound that's coming from right below the car. I think it's coming from the gear shaft but I'm not a car expert so I can't be sure, it's more prevalent when I shift into reverse. What it could be? The car is still completely under warranty so I'm fine with making it the dealer's problem.

When I make a right turn and bring the steering wheel back to center, I get a vibration. The ball joints were replace a year ago. The dealer put on a reman half shaft 2 months ago. I got an alignment and had the tires balanced and still no resolution. Still have the original struts after piling up 249k miles (lot of driving as a courier). It's a 2010.

I got a 2007 Hyundai Sonata Limited, 6 cylinder, 3.3L, at 110,000 miles and since I bought the car, I always had a vibration when the A/C is on. I can feel it in the front of the car somewhere where the pedals are. Ones I turn off the A/C I can feel how the vibration causing thing stops. Is it normal? Can it be one of the A/C motors?

My 2005 3.3 V6 NF Elite has developed a vibration under acceleration. Its not always apparent, but certain road surfaces, and certain rates of acceleration seem to make it worse, when it can be felt throughout the car. The drivers side CV is beginning to click, so will need replacing soon, and I suspect that some bushings around the suspension are worn, as they are squeaking. Could those issues cause such a vibration.

I recently had new rims and winter tires installed on my 2007 Hyundai Sonata 4Cyl from Walmart. When I left I noticed I had a vibration in the steering wheel at around 50-70 km/h so I took it back the next day and got them rebalanced. After the rebalancing I asked the tech. if it was off and he did say they were just a little bit off.
I took it out for a drive and the vibration is gone from 50-70km/h, now it is vibrating from 70-120km/h. I was about to take it back for another balancing, but as I was driving home today and had the car on cruise control and cruising at about 110-120km/h I noticed the vibration would go away sometimes to virtually nothing, then come back with very noticeable vibration.
So now I am beginning to think it has nothing to do with the balancing of the wheels but maybe something in my suspension. I am getting some clunking sounds when I hit bumps and you can feel it through the drivers floor, pedals and steering wheel. I had friends tell me that it may be a tie rod end or strut mounts.

I went for my regular oil change and I asked my dealer to look for a strange vibration coming from the front wheels mostly noticeable at 30KMh and over 70. He diagnosed a vibration coming from the tranny. Wheel bearing are fine and tires and brand new (Toyo Tourevo) and freshly aligned.
My dealer opened a case with Hyundai Canada to have my tranny changed. BTW, Sonata NF 2010 I4, 5 speed auto trans. 50,000KMs

I bought a second hand Sonata NF 2006. Excellent car. At the beginning to me was hard to tell if the car were running or started because of the silence and non-vibration at all.
but, recently I think that I can hear a little click click noise, no the normal one, another and some vibration on the steering wheel that wasn't there before.

My car has been vibrating under acceleration since past 2 months. It isn't present in first gear but is evident in second and third gear ,and increases with more acceleration. I replaced engine mounts as they were shot,and got the wheels balanced but the vibration still persists

I've noticed that when I am driving my car in the morning there is a slight vibration in the car, it feels like the rear, but it could be the whole car. After I drive it for a while this vibration goes away. The vibration never comes back again until the next morning, even when the car sits at work for 8 hours the vibration doesn't appear.
It's not a violent vibration, it's very subtle but it is noticeable. I'm thinking that most likely it is my struts and shocks, I know that they probably need to be replaced soon (with our shocks being crap).
I don't think my wheels are out of alignment as the car doesn't pull to any side at all and my brakes are also good and not sticking. The car has 86K on it. What is going on and if I should be more concerned than I am or is it just worn shocks and or struts?
