U-JOINT, DIFF., or TRANS
My '88 F250 custom has a winding noise when getting on the highway or when accelerating quickly from a stopped position. The faster I accelerate the louder and quicker the wind. I got an answer that it could be the U-Joints, or the Differential, or the Transmission - in that order. What is involved (how to) in determining or diagnosing and fixing the U-Joints or Differential if that is the problem.

First of all, unless your trans is slipping this is not it.
2nd you want to check all of your ujoints. You can do this by putting the truck on a flat surface, and blocking the tires. Set the parking brake and put the truck in neutral. (not running of course). now crawl under the truck and move the drive shaft up and down and try and turn back and forth, if you see any play replace the joint you see moving. check everyone and if you have a two piece drive shaft also check the support bearing.
If you dont find anything wrong with the joints, the problem will be the differential.

Just so happens that the airline was rusted at the converter and then the check valve on the other end to the O2 sensor come off and when I replaced the line and buttoned everything up the noise went away.
