1964 Valiant "Get Runnin & Drivin"
@qkcuda
Can't think of everything all at once.
If you pull your drive shaft. Then grab the pinion yoke by hand and rock it back and forth to feel the ring gear to pinion gear lash, should be around. 012 ths if this feels excessive there, then there is a good chance the carrier bearings are wore enough to send it out of spec and make it whine.
This happened to my 2000 Ford E150 van, put in new carrier bearings, and it broght the ring gear back into spec again and my gear whine went away.
Good luck on your project.
