I recently installed a used 3.73 pumpkin into my Lincoln and it's making a speed-sensitive howling noise that comes on during acceleration, prominently around 30mph, and is less evident while coasting and decelerating.
The previous owner declared the rear end made no noise, so I'd like to rule out ANY other possible explanation before I tear down the rear end.
Thoughts include rear wheel bearings, halfshafts, driveshaft/u-joint issues. For reference, there was NO evidence of this sound previous to install.
I'd appreciate it if you guys could throw some possible explanations out there so I can rule them out.
Thanks as always,
Phil
