Axle questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is my front axle (D44) a closed knuckle, or open? It has the balls on the end of the axle that the brake drums sit on, not the U-joints if that helps. Will drum brakes swap from a closed knuckle to an open knuckle axle or vise-versa?

Will my rear drum brakes bolt on to a Dana 60 form a F#rd truck, or are they different?

Sounds like you have a closed knuckle front. Not sure on the drums. I'm thinking they wont, Ferd used bigger hubs, and GM wheels won't always go on.....

your rear is an eaton, I agree, I don't think the drums will go onto a ford d60

You sure about my rear end being an Eaton? It looks like a Dana to me, and the trucks all original.

If it's a GMC then it would be the Dana 60, Chevy uses the Eaton. Either way I don't they will work.

Ok thanks.

I just purchased the exact truck you have as a parts truck for my '69.
Your truck should have the closed knuckle d44 front and full floater d60 rear as mine does. Good luck working on your truck.

Huh, thats pretty neat! Never did see a truck that was exactly like mine.

69gmcfleet · 02-28-2006, 05:14 PM

My '69 was exactly the same as your '68 when I bought it 6 years ago, plow and all. It was all original with very little rust. Then the V-6 died at 100,000 miles. I have since put in the 350 and changed the gears. I do not drive mine in the winter anymore. I consider these GMC's to be rare. I have never seen another one in my area and get many offers to buy mine. I was shocked when I found the '68 at a local repair shop in the back lot. I got it for $500. It will be my parts truck for my '69 since the running gear is all the same. I love the old GMC 4x4's. It is good to see another one kickin' around.
