#1316 of 1325 Improved Suspension & Less Noise
May 14, 2012 (8:46 am)
I own a 2006 Azera with 90,000 miles on it and the suspension has always been inferior. Tire noise both front and rear along with a rough sloppy ride. Replacing the tires will only hide the problem temporarily. Here is what helped the suspension and the noise more then I could imagine. I removed the front wheels and in the back of each wheel well is a plastic cover. Remove the plastic cover and using spray glue install Thick Dense Foam from top to bottom. The key here is Dense Foam. Then replace the plastic cover and seal the edges with a 3-M under-body coating. Now install a rubber coil spring doughnut between the springs at the very top. You will need some silicone and a piece of wood to bang the rubber doughnut into the springs after you get it started.
In the rear of the Azera use a Quality Sound Deadening Material. Remove both sides of the trunk panels and insulate both rear wheel wells. Also run the Sound Deadening Material in the space in front of the spare tire or right behind the rear seat. Now remove the rear tires and the plastic cover in the front of the wheel wells and insulate behind the plastic cover. Replace the cover and seal the edges with the 3-M under-body coating. Also install a rubber doughnut on the Bottom of each rear spring.
It's like a different automobile. Quieter, the front end is more stable and the improvement in the ride is amazing. A little work but so far well worth it. New tires, shocks and upper strut bars and I think that would really make it ride like a luxury car.

Just had one of these panels fail and was charged by the Dealer as my 07 azera has 63,000 and is over the warranty. Called Hyundai and they inform me there is no TSB for the 2007. If you have a TSB number, please post it so I canc all them back and try to recover the money I paid.

could you tell me what kind of rubber donaut did you put in your springs? did you put only in front or rear too? did it raised the car a lot? isn't it unstable beening higher?
i also did some mods to my azera. koni struts heavy duty strut bar and thicker sway bars. best result is from sway bar so i think the problem isnt in shock absorbers alone but more in too soft springs setting.
strut bar also did a lot to improving the ride.

Sorry for such a late response to your Question about the rubber doughnuts I put between my springs. I purchased them at AutoZone. They are round and about 4 inches in diameter with a concave groove on both sides for the spring to fit into. They are also split so you can kinda straighten them out to get the end started in between the springs. You have to remove the wheel and let the spring hang so the spring will open up a little to get them in.
If they raised the car it was only a quarter inch if even that much. I put them in the front at the top of the spring and in the rear at the bottom of the spring. You are absolutely correct, the springs are too soft.
Where did you find a thicker sway bar? I found a front upper strut bar that ties the two front shocks together under the hood without any modifications required. Just do a search for Hyundai Azera strut bar I think it was KFX.com $99.

Thanks for reply.
But i think i will not put anything into springs as i am going to sell the car. Beside the too soft spring there is another problem to the cars suspension which i detected and its difficult to correct as it is a a factory missdesign.
The thiker sway bar is all the way from korea from kspec.com site. Its quite expencive. Also i got the strut bar from Luxon Korea. No offence but the strut bar that you got is no good. It is too thin. First i got one like this and it did some efect but nothing like the super heavy duty luxon bar. I can send you some photos if you like my mail is viki6orgmail.com.
Also i can sell them if you like them. As i am going to sell the car with this upgrades so if you want them i can get them off the car.

This is THE solution to the problem. Thank you. So far, I've only installed the rubber donuts on my '06 Azera, but that alone made a huge difference--brought the suspension from "intolerable" to "acceptable." Rides less like an old Buick and is much less bouncy/wavy. The body rides about 1/4" higher, which is fine--even preferable, I think. Again, thanks. My wife and daughter no longer get car sick!
#1322 of 1325 Suspension Clunk
Mar 27, 2013 (8:00 am)
Okay...I'm proud to say that I've owned my '06 Azera for the last 7 years and put just over 146k miles on it. I've read all the posts about people complaining about the clunk noise, which I didn't experience until about 80-90k miles. All the years of going to the dealer and having them look at it, not one time did a mechanic ever mention anything about the sway bar bushings. My mechanic told me that sway bar bushings can wear out anywhere between 20-80k miles. So...I am going to order them and have him install them and I'll come back and let you guys know if it resolved the infamous clunk noise or not. I tried to find some silicone aftermarket bushings to no avail, so I will just try to order the best ones I can find.

I for one am looking forward to your next reply.
I just had my upper control arms replaced around 78K, on my 2006 Azera. I've been experiencing the "Clunk" for a while now and my Hyundia Advisor feels it's the Strut mounts. When I take it in for service next week, I'll have them to check the sway bar bushings.
Thanks for info.

Antonyr...initially I was experiencing squeaks and other noises that replacing the upper control arms took care of. While the strut mounts can produce noise, it would be a noise you would hear towards the "top" of your car. The sway bar, being underneath your car would produce that noise that sounds like golf balls loose in a box sound.
Unfortunately, I have to get my ignition coils replaced before I take care of the sway bar bushings. If you get yours done first, by all means let me know. Of course, I'll post regardless when I get that done.
Happy Easter if you celebrate, if not...have a great weekend.

...I am posting my results from getting the sway bar bushings replaced.
Sway bar bushings - $6.48
Labor for installation - $198
Clunk/rattle noise gone - PRICELESS!!!
For any Azera owners that have any front end noise (clunk or rattles), please do yourself a favor and get the sway bar bushings replaced. After 7 years and 150k miles, the suspension ALMOST sounds as good as it did when it was new. I guess I had gotten so used to the noise that I forgot how good & quiet the rode before. Truly a night and day difference.
Now I've got a few other things to tend to on the car and I think I'll be ready for another 150k miles!!! Just so you other Azera owners know...once you hit the 100k miles mark, start thinking about your 02 sensors, spark plugs, ignition coils and serpentine belt. Other things I have to replace are the engine/transmission mounts, an A/C pressure switch and the original rotors.
