10 bolt front under 1970 c-10? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

dmigura · 07-22-2005, 10:13 PM

Just exploring more options. I want to Change my front d44 drums to disc brakes, and I am starting to understand the parts swap from a post 71 dana 44. But I have another option just sitting in my back yard. I have a 1980 3/4 ton w/a 10 bolt front and a 14 bolt rear. both are solid axles. I think I would have to move the perches on the rear, but is that all. Is the front a direct bolt in? Steering and all? If so this seems cheaper and easier for me than trying to round up new d44 break parts? Also would these axles be and upgrade or is the d44 a better axle.

Thanks

I think the front would be a simple swap, though i have never owned or seen someone do the swap. The rear will need perches moved, or get a 1 ton 14 bolt which will have the same perch width. Any one correct me if im wrong, this is just stuff ive heard.

I agree. See how it works, I used my drum brake master cyclinder w/ disc up front and have had no problems.

The front should bolt directly in. The only issue with the rear aside from the perches will be the parking brake cables, you may have to move the anchors on the frame and get a longer intermediate cable.

the front will bolt in, i got a parts blazer, and the p/o alreay swapped the 44 for a 10 bolt in it..
good luck

also, the 10 bolt will be stronger than the 44 because the axle u-joint is larger. You'll also gain a few degrees of turning radius.

It sounds like the 10-bolt might be an upgrade. Also is there any issues with the u-joints, I mean can I use my oringinal drive-shafts (front and Back)?

Thanks for the help

The 10 bolt is a direct bolt in, but the 14 bolt will need the perches moved. That's what is in my truck in my avatar pic. Since you are currently running half ton and switching to 3/4 ton, you are going to have issues with shafts and u-joints. Someone correct me if I'm wrong on the shafts....... Good luck

i think big70 is right on the drive shafts,they usally take the bigger yoked shafts, but you might be able to just change the yokes off the axles to match your tranny/xcase but it won`t be as strong....

you can also get a special u-joint to go from 3/4 ton axles to 1/2 ton driveshafts, it has 2 large caps and 2 small (about $17 each)
