Here is that thread.

Could be a CV joint. It could be anything. I was reading another thread of a guy having a vibration issue on a 2500HD and the description on part of his problem fits mine some. I think my torque converter is making the same noise he hears on his truck. I guess it could be that. What is weird is does not do it all the time.

I just noticed I placed this in the wrong place. Sorry about that, I hope it can be moved.

I have a 2013 2500HD that I have owned since 2018. 180K miles. I have quite of bit of vibration at 60-70 mph. I replaced the tires and wheels several times. I was getting used tires and wheels now I have new Michelin defenders with 17" aluminum factory wheels. When I got the new tires there was no change. I took it back to shop and they found 2 things, worn bushings on the A-arms and the steering idler arm. I replaced those and they lined up the truck. It is better but still not as smooth a ride and I think it should be. Any other things in the front end on these trucks I need to look at? Any help is appreciated.
