Question about front axles ?
The '67 C20 I just picked up has a closed nuckle front axle.
Don't know if that is right or not, wanted to know the + & -'s for that type of axle ? Dose anyone know? Thank you Landon

It means that you can only run drums on it. If you want disks on the front, you will have to swap out to a 71 or newer axle. Don't know what else to tell you except that they work fine if maintained. So do the drum brakes if adjusted right. Jeff.

It is most likely a Dana 44 HD, which is what I have in my 1969 K20. I have had my truck for about two years now with no trouble until about two weeks ago. I had the internal u-joint on the drivers side break on me. I haven't fixed it as of yet. Other than that I've heard that they are good axles.

In the 44HD closed knuckle, supposedly the u-joint is stronger than the 73 and newer 297x u-joint.

I never had a enclosed knuckle frontend, but i read in "4wheel and off road" that they dont work well with lift kits. Has any body else read this?

I haven't heard of them having problems with lifts. Mine is doing fine. Like stated, the turning radius sucks and of course gets worse with bigger tires that you just gotta buy after the lift.
Mine will go bye bye someday so I can have disc brakes and something stronger.

ttt
I was thinking about turning it into a super stock pull truck. It is '67 C20 4X4. That is why I was asking about the + & -'s of the closed knuckle front end. And If I should ever get around to making this pull truck thing happen I will post pic's. I must get my truck done first. Thanks for all the input guys!!!

The closed knuckle I had in my 67 worked just fine. The only reason I could see to get rid of it (which I did) is to install a later model for the disc brakes. I still have mine, Dana 44 6 lug 4.10 gears. If you want to make the trip up from Hollister, you can have it.

Closed knuckles leak and wear
The 69 I have had a closed knuckle front end and over time and a lot of bush miles the "balls" on the ends of the axle housing where the felt seals go wore out (about a 1/8" groove worn in them). Consequently, I can no longer properly preload the felt seals and therefore the lube leaks out of them. When I did the frameoff, I replaced the front end with one from a 72 with disc brakes - imo, much better.

If one is not enough to inspire you, I will give you one too! I am about to take one to the salvage yard. I heard that the mudrunner guys like them because of the closed design but I don't know if that is true.
