And it's not the beans...

The Previa has a rear end issue. I found a possible solution on the net with a loose pinion nut but I tightened it up and I'm still getting the roaring noise especially at highway speeds. I replaced the end seal at the same time because it was leaking badly. I wonder if it could just be the pinion bearing. I can feel a roughness when I rotate it by hand. It's so loud I'm beginning to worry about my hearing. I'm contemplating replacing the pumpkin. I guess I should try to get a peek at the gears to see if I can see any damage. I know the sound and feeling of a bad bearing and it seems to be similar but it could be the diff, I suppose. Is there any way to be sure without dropping the whole thing? Can a bad diff cause poor FE?

The good news is I found a rear drum dragging which I loosened up so that should help with the FE.

Hope your vehicles are running smooth.
