general problems of the 2004 Chevrolet 1500

Took the truck to the chevy dealership for pulsating brakes and a weird 'clunking' noise/feel in the steering when cornering. They replaced the rotor assembly, but never located the cause of the steering issue. This issue has continued to this day. Last week I met another chevy silverado owner who had experienced the same problem and had received a recall on this issue. I've never been notified nor have I seen the bulletin on this site (he recommended this site to obtain the data). His vehicle was the same make & model, but one year older (mine is a 2004). This 'clunking' noise/feel is consistent when turning corners in either direction. It effects the performance feel of the vehicle. And leaves us wondering if the steering box is about to fall apart at any moment. Please advise if recall has in fact been issued for this make & model year.

There has always been a knocking noise, that can be felt in the steering and brake pedal. The dealer replaced a shaft that connected to the steering sector. The fix corrected it for a while. The problem came back. I went back to the dealer and was told the part needed to be removed and greased every 15000 miles. I said ,why does it not have grease fittings? over the last 10 years I have talked to numerous people who have the same problem. I sent gm an e-mail about this problem, never got an answer. I do get letters from gm wanting me trade for a new one. Why pay $40 to $50 thousand for a vehicle that the manufacturer wont stand behind? thanks richard avery.
