....2009 Silverado 3500HD, DRW, CC, 4x4. 32609 miles, it's not a daily driver and sees mostly camper hauling or trailer towing duties. The idler arm and pitman arm are toast. /rant off.
We have a 2003 2500HD duramax. Our truck had the same issue at 43.000 miles. a 1500$ repair bill ouch. GM did a good will repair and picked up all the costs but the the new tires and 150 labor. I have 129,000 on the truck now and have not had any problems but an injector go out! a whole other story. But Ten years and still going I love the truck.
