Haven't been on here since Google Chrome started blocking the page. I haven't been able to take any action to try to track it down, yet. I know my front rotors are warped, dunno if that'd cause a vibration?

I changed the diff fluids a couple years ago; kept 75w90 in there. No noticeable difference. Thought it was a wheel bearing for the longest time but the bearings are quiet. Made me think it might be a driveshaft u-joint or center bearing. Gonna try to swap out front axles soon and see what happens. Failing that, I'll drop the driveshaft and replace the u-joints and center bearing.
