OK so I have a high pitch wine starting on the 2011. I changed VTM-4 as it's been 30-40K miles, it was clean and did nothing. Last time I got this type of noise my drive shaft was seizing and stressing things so I checked that. Unbolted front and rear and U-Joints are moving fine center bearing is tight and no slop. I jacked it up and spun and push/pulled on all the wheels and no play in bearings, they are tight, things spin fine BUT there was a slight drag on one brake half way around each rotation that may be a slight rotor warp. Would that be enough to have a loud whirring/wine at 50-70 MPH? I will pull that wheel and address the drag with a grinder if need be but what else could this be I might be overlooking. It starts at 30 and builds to 70 and is pretty consistent. As you come to a stop you can hear it whirr down until 30ish then goes quiet. If it was pully's or alternator etc. I would expect it to change with RPM on the engine and it doesn't at all. Revving at a stop = no noise. Have to be moving. A bit stumped. Gonna pull the wheel with the drag and try and fix that but give me thoughts on other things. Maybe it is a bearing and it's just not gone far enough to have play, but how do I find which of the 4 to change. 136K Miles on original wheel bearings.
