Yup, almost 2 gallons. I bought one at the parts store that night before I tore it apart, about 7:30 PM. By the time I got to filling it back up, around 9:30, after the parts store is closed, I find myself rather lucky to have an extra gallon stashed in the underbody box... it took over 7 quarts, the 2nd gallon only had a little bit left when I was done.

So how long can I get away with this lighter oil? I haven't been pulling anything, just daily driving. The ammount of noise the pinion is making makes me uncomfortable, but it's not so bad you can hear it over the noise of the truck while driving. I only heard it 'cause I had a sethoscope and was under the truck while it was on a lift, running. Everywhere I put it, brake backing plate, center section housing at the axle tubes, and at the pinion, the center drive shaft support bearing, the transfer case tail housing, all had a nice smooth hum, exept the front of the pinion snout buy the yoak. Noticeable diffrence there. And this is with the drivetrain running at 50-60 MPH... (I have to admit, I was scared... I don't like being under a 9K lb truck on a lift in the first place, but while running also?!?!?!)
