How many do you put in a rear for noisy bearings?

You fill up the rear differential through the upper plug. When the fluid starts running out of the hole, it is full. Make sure you are parked on a level spot. I doubt if it will help for noisy bearings unless you are really dry.

Can I use it for automatic gears?

I have a very tiny wheel bearing seal leak, would this work for my 2003 Grand Marquis Ls?

I had the same kind of leak in my 2000 Silverado with 240k. I changed the gear oil and added this , So far it has stopped the seal leak.
