Strand intermittent vibration
I have a 02 suburban. After driving for about an hour, there is a vibration that is not related to engine speed, but is related to wheel speed. It'* pronounced at high way speed. It'* similar to a rumble strip. It'* not a bearing, as it'* the same turning either way. Rotated tires, no change. I'm thinking u joint, front diff, or transfer case. Just had the trans pan off, pretty clean. Thoughts? Thanks!
