Suspension Noise problems of the 2007 Hyundai Santa Fe

2 things are concerning. One, when driving over small cracks, bumps in roadway the suspension makes a noise that makes me think it is unstable. It is also a louder than average noise, compared to past vehicles that I have owned. Second, driving at speeds below 60 mph, everything is normal. Once speeds above 60 are reached, the steering column shakes and vibrates. The noise described earlier in paragraph one is heard. Alignment and balancing are normal. Tire tread is also normal. Neither of these two are acceptable and in my opinion is a risk.

When driving at any speed and going over any minor irregularity in the road surface, distracting noises from the front suspension. . . Squeaks, creaking and thuds are best word to describe. Very disturbing as nothing is visible according to mechanics but there is an internal problem due to the hundreds of on line complaints I'm seeing.

Owned vehicle since new and have had all services performed. Currently 72,000 miles. Car has been plagued with clunky, noisy suspension problems since about 35,000 miles. Noises and ride at all speeds are so bad that this has to impact potential safety. Dealers have replaced power steering rack; pinion; p/s sway bar; link assembly; lower control arm (2x); p/s front stabilizer link; l/f control arm, bolt and nut. None of the "fixes" have lasted more than a few thousand miles, and we were right back to where we were. We are "easy drivers" who do no offroad or rough road driving. Were it not for these issues, this would be a "decent" SUV.

Second set of tires cupping. First set replaced at 23000 miles. Current tires bad at 58000 miles. Have no reason for this. Tire rotation done every 5000 miles. Tires not over-inflated. Not alignment issue, although alignment was done and bolts replaced at 23000 miles. Sounds like a Hyundai suspension problem.
