Default Hum after rear-end gear change

Pretty much what everyone in this thread has said.

The best way to go about it is to get a complete used differential/axle
with the ratio you want. Ford rear ends take a very long time to wear out.
The only one I ever had that made any appreciable noise was an 8" that had
over 600,000 miles on it. The 8.8 in my '71 Galaxie has over 240,000 on it,
and is quiet as a mouse.

On the other hand, mechanics who don't understand how to set a rear end up
properly (and they are few and far between now) can cause a lot of trouble
in a heartbeat.

I read over the procedure in my 1969 Chilton's book, and it isn't anything
I would want to tackle.
