Steering Tie Rod Assembly problems of the 2004 Chevrolet Silverado 1500

After purchasing a 2004 Chevrolet silverado z71 in November 2004, my 1st complaints were in November 2004 for a rear clunking. After several trips to the dealer the driveshaft was replaced, along with recalled tailgate support cables, rear bumper (rust), spare tire guide retainer, license plate lamp lens, and transfer covers, and, except for my time, all were covered under warranty. In February 2005 I complained of a grinding noise in 4 wd. 4wd transfer case fluid was drained & refilled. In June 2005 I complained that the 4wd switch went into neutral; 4wd software was replaced. In August 2005 I complained of clicking in steering wheel, burned out light bulb, and clunk in driveline; steering shaft was lubricated, bulb was replaced, and driveline splenes lubricated. Driveline splenes again lubricated in September 2005. Transfer case fluid changed. Complained that 4wd high inoperable when I couldn't pull my boat out of a lake, but dealer found no problem. In January 2006, both outside heated mirror glass assemblies and left side heated mirror assembly were replaced; the ignition lock cylinder was lubricated due to key getting stuck; 4wd transfer case fluid drained & refilled; transmission column shifter assembly replaced. In may 2006, flasher module assembly was replaced due to flashers going on when signaling; tow haul mode switch assembly was replaced due to indicator staying on. Purchased a 24-month warranty. In October 2006, the blower motor resistor assembly was replaced as fan only worked on setting 5 (I was charged $40. 26 for a resistor). Remotes were programmed for lights to flash with keyless. In March 2008, left front hub assembly was replaced due to a grinding noise; due to clunking noise, both inner tie rods were replaced; steering wheel noise was still there. In April 2008, heater control head assembly replaced. The steering wheel still clunks and vibrates when turning. I feel it is a serious safety issue.
