Hey fellas, new to the site, this is my first post, hopefully I'm in the right section. I test drove a 2010 duramax yesterday. The truck has 150k miles on it. The truck ran fantastic. My only concern was the steering felt a little rough, it's kinda hard to explain. It turned fine driving or sitting still, the alignment seemed fine I took my hands off the wheel while driving and it stayed straight. It didn't have any noises or pops or anything it just felt a little rough. It has 20 inch denali hd wheels and tires on it. I'm not sure if that had something to do with plus this is the first duramax I've driven so I'm not sure if they just feel a little different than the gassers. Again it ran and rode great just fine didn't feel as smooth turning as my '05 2500 gas that has 210k on it. Is there something specific I can look deeper into on this? Thanks.
