Steering Linkages problems of the 2005 Chevrolet Malibu

For several months, I have both heard and felt a "creaking" in the front end of my vehicle as though metal parts are loose when the car is put in motion both backing and forward, turns in either direction. I did bring this condition to the attention the local Chevrolet dealership where I bought this car and where I have had it serviced since then. They indicated to me, they could not find a problem, could not hear or feel any condition, and further stated there was "no fix" from gm. However, this condition appears to be getting worse and not recognized by the service people at the dealership. My concern is, at some point, could or will the front end fail when the car is in motion which is a clear safety issue. The dealership did point out that the tires have some wear on them and it is my feeling the tire wear may be caused from this condition.

Steering pop when turning car, on 2005 Malibu maxx.

My Chevrolet Malibu maxx (2005, 17k miles) frequently has a clunking noise that appears to be coming from the left front suspension. The noise is often accompanied by the feeling of a "hit" underneath the driver's feet and on occasion seems to be connected to a steering input (steering wheel moves notably). This happens only at lower speeds (below approx. 35 miles/hour) and during or after left turns and is especially strong on uneven roads. I took the car to a certified Chevrolet dealer for repair and have been informed that this clunking is related to a problem with the intermittent shaft of the steering, that this problem is known to Chevrolet and has been assigned the number pic3747, and that no repair is possible at this time. They also told me that they have no data indicating that this problem is at the same time a safety issue. But as I have a notable steering input, and as the constant clunking is also interfering with concentration, I consider this a safety issue and thus filed this complaint regarding this problem.
