9" rear in a jailbar truck

Sounds like you got it figured out Gary so maybe you already know this. Throwing it out there anyway.

Some of the gear lubes on the store shelves will have the limited slip additive already added but it will say so on the label. If you filled with oil that does not contain the additive you can buy just the additive and save draining your fresh oil. The additive is pretty smelly stuff.

Even after you add it, it takes a few miles to get soaked into the clutches and start working.

They ARE nice to have over an open diff. And not quite as harsh as a locker.

Yes, thanks Scotty, I'm getting educated in yet another new realm. Just made a run to napa and got the additive to mix in with yesterday's GL5. I found some photos on line of ford trac-loc differentials and compared them with a photo I posted on this thread after I uncrated the 3rd member fron Lanny. Sure matches up to be a ford trac loc. There is plenty written online about the noise and vibrations when the clutch pack does not have the friction modifier and it chatters on slow cornering. Supposed to add it to warm differential so the cabinet work will have to wait til I go for a warm up, then the mix, then the test drive. Sucks to be waiting for cabinets from Mt Pickett Woodworking... But a guy has to have his priorities straight.

5:40 am, 2 cups of coffee in and I'm heading down to the cabinetshop to make up for lost time. The additive did the trick and wife and I drove the woodie out to dinner, then up the winding mountain road in the state park, followed by a run down to the old boatyard at Obstruction Pass. Thanks to all who helped make this happen.

Sounds like you're all set for the big Fourth of July parade! I'm sure Woody is looking forward to riding on the front grille for all to see.
