So I’ve had multiple issues and repairs on my 2014 express 1500 v6. Rebuilt transmission, just had a whole new rear differential installed, now it’s making a rubbing noise when turning either direction at low speed. Weird thing is after I drive a while, it doesn’t do it anymore. When it sits on a job site for a few hours, it’s quite loud again until after a while of driving again. Any ideas? 241,000 miles.

 

"rubbing noise" could be a lot of things. Best thing to do would be get up on a lift, or crawl underneath and look for signs of scuffing. Since it's only while turning, I'd focus on the front wheels + tires.
