Balancer
Had mine replaced last year. THe GM tech said it was one of the most common problems in C5s. I had a squeel which we assumed was coming from the belts or tensioner. He showed me in spite of no vibration how it was wobbling under a light. I chose to go with a factory parts.

The steering rack is also about a bazillionth of an inch in front of it. The C6's were having problems with the bolts backing out, taking out the steering rack, spraying PS fluid everywhere. From what I read, the fix was a new balancer, bolt, steering rack and paint job on the car
