I have a 2014 Sierra. For the last couple of months, there is a "rumble strip" type vibration that occurs seemingly from the center-front or front-right of the truck. It occurs at all different speeds, and happens a lot while coasting, or light accelerating. The biggest issue is, it happens randomly, sometimes only a couple times for a few seconds each if I am driving 15-20 minutes, so it's a hard issue to replicate for a mechanic. I dont want to take to dealership or mechanic and rack-up charges to try and diagnose. It would be great to at least point someone in the right direction.
I had the transmission rebuilt almost 1-year ago. The shop that rebuilt is 2-hours away, so I havent been able to take it back. However, the truck shifts totally fine and doesnt feel like transmission. I have a 1-year warranty, so I can take it back if needed, just doesnt seem to feel like a transmission issue.
I have replaced many wheel bearings over the years, it doesnt feel like that.
Has anyone had this issue before? Any thoughts or recommendations?
Thank you all so much for any help!
