2003 GMC Sierra truck, steering, has a clunking noise started about 5,000 miles, told by mechanic to take to a dealer, was not the first time he had heard of this problem and was not something he wanted to undertake due to liability, another problem with to much play or (slap) in the drive shaft, took it to dealer they replaced drive shaft, did not solve problem, so apparently they did not know how to solve problem and basically were grabbing at straws, I still have problem, front running lights keep burning out (electrical problem).

2003 GMC Sierra 1500 pu truck - corroded and failing hydraulic brake lines. This truck was purchased new by me in October 2003, and now has only 23,700 miles on it. A line near the fuel tank, which feeds the rear wheel calipers, rusted through in January 2009. Other lines in numerous locations also show signs of corrosion which will lead to future failures. Mechanics in this area tell me this is very common, even on some newer GMC (and similar Chevrolet) vehicles. Some of these mechanics replace the faulty lines with tubing which is more corrosion-resistant than provided by the manufacturer. A couple of weeks ago, one of the rear, rear wheel emergency brake cables on this vehicle also failed due to corrosion, and the other one showed signs of the same failure impending. Both were replaced. A serious, fundamental and compound hazard exists under this scenario. The manufacturer should be required to recall thee vehicles and replace all critical brake components subject to corrosive failures with corrosion-proof (or at least highly corrosion-resistant) parts.
