My 1934 Master Coupe has a noisy rear end when applying power (silent otherwise). Kind of a low howl... Just did a frame off restoration - guess it was probably there but I didn't hear it before.
-Inspected and everything looks okay. Ring and pinion seem fine, no abnormal wear. Bearings fine - replaced axle bearings a couple years ago.
-Running 600W grease - changed from the 80W-90 that was in there about 5 years ago. Replaced last month anyway following inspection - no change.
Thoughts? Something I should worry about?
Thanks in advance.

If it wasn't there before and it is now and the only change was the viscosity of the lubricant that's where I'd look first. The manual say to use 160 weight, 90 in the winter. I'm no expert but 600 sounds way too thick to me.

First the gear oil has nothing to do with it,
A howl when applying power is most commonly caused by the front pinion bearing.
Can also be caused by a bad ring pinion gears or their addustment.
I used 85W-140 in my cars to cover all temps including my 1934 Master.
