Steering Column problems of the 2006 Chevrolet Silverado

About a year and a half ago I started hearing and feeling a light knocking in my steering column when I would make a turn. It took several months for it to get consistent for anyone else to hear it then it began to get a lot worse. I took it by my mechanic and he told me that it was in the steering. He said that they use to just lube them again but now you have to order a kit from the manufacture. He knew what the problem was immediately after driving it through the parking lot because he had the very same problem on his chevy truck in the past and had seen several others since then. He informed me it was safe to drive for now and I have yet to get it fixed. You can tell it is a lubrication problem because it is not as noticeable in the winter vs. The summer when it is hotter and the lube flows more freely. Now I see the same complaint on here and other web sites regarding this same problem and that it will keep happening over and over. The knocking has become very loud when I make a turn either way now. If this is a known problem with this model then why has it not been recalled? especially if a owner has to continually have it fixed after every 10-20 thousand miles. I am afraid that if it is not fixed soon I may lose control of the steering. I have also noticed a lot of wear on my tires that should not be there after keeping it continually maintained. My truck is five years old but it only has around 25,000 miles on it. Please I urge you to look into this problem before someone does end up hurt.

The contact owns a 2006 Chevrolet Silverado. While driving 25 mph and making a right turn the steering wheel locked. The contact was able to slow down and come to a complete stop. The manufacturer was not informed of the failure. The dealer diagnosed the failure and repaired the steering column but the contact is concerned since the repair didn't correct the failure. The steering wheel has continued to lock while driving. The VIN was not available. The failure mileage was 2000 and the current mileage was 89397.
