Sedans Hyundai Sonata Hyundai Sonata Front Suspension "Thunk"

I've begun this Discussion topic since the thump/clunk issue relating to the Sonata suspension has been largely addressed in these forums as relating only to the rear suspension of 2006 models and a few early 2007s. However, it also seems to be appearing in the front and/or rear suspension of 2007 models - namely in mine. I have a Limited- manufacture date Aug 2006 which has the "thunk" largely in the right front, but exists to a lesser degree at all three other suspension positions. So far, I have examined on my own (since Horne Hyundai in Apache Junction AZ said, "We can't hear anything.") the lower control arm strut bushing (as advised in other posts for clunking Azera's) without seeing any visible space as the writer of that post did in his. Next I plan to retorque the upper strut mounts to factory torque and will report my findings. Since the problem is easily reproducable on certain bumps on which I travel almost daily I plan to ask the dealer mechanic to ride with me while I drive over those areas instead of simply dropping the car off at the dealer as I did last time. In the mean time I'd like to open this up for anyone else who has experienced the "thunk" in front positions (or rear positions if it also occurred in the front and both were fixed, or you have information which might relate to front suspensions) for 2007 models. As others have reported, when we have evidence that this is not an isolated incident then we have a much better chance of getting Hyundai to address it as an issue. Thanks for your input.

Replying to: comet64 (Apr 10, 2007 5:53 am) In response to "comet64": regarding your rear thunk that was fixed. Do you know what they did to fix the problem? Did they replace the shock portion of the strut with different ones, or just tighten something? If you do not know, could you possibly find out? Thanks in advance. FYI: My "thunk" problem is able to be demonstrated every time on a road indentation (or weries of them)like a pothole that still has pavement in it, or a smooth manhole cover that has not been leveled to the road surface well. Holes which are severe also cause tire and body noise which tends to mask the "thunking" to some extent. I recently had occasion to drive on a road that was a solid city block just full of temporary paving and patches due to a utility construction project. It constantly "thunkity thunked" all the way down the block. It sounded like a 10 year-old car with worn out ball joints rather than a new car with only 3000 miles on it. Unfortunately it is a long way from a dealer. My next project is to find a street that will produce the "thunking" near a dealer.
