I just got my truck(2005 lly 2500) back from the shop, It was in for steering shaft lube, and the diesel tech also says I need to get a few new injectors. My big complaint was when I was in 4X4 slowing down to 20km and then hitting the gas a loud bang/clunk comes from the front end of the truck, but the tech says 4X4 is OK, any suggestions would be appreciated. Cheers!
