10-bolt front end

[stm3784]

hey all,

I went to the boneyard today pretty much because I could. And they had 77 k20, with what looked like a10 bolt front axle. Anyway the question I have is. I know there are guys the would much rather the D44. But I’m trying to find out, and I know it’s dumb, I probably already know the answer but the 10bolt and D44 axle on the K series truck, were the SF, FF, or both? Also how can you tell? I know I rambled, sorry. I’m at work and bored.

I'm not sure of the technical term, but I'm pretty positive front axles are neither semi float or full float, not completely sure though. I say this mainly due to the fact that there isn't a straight axle shaft all the way to the hub flange where the wheel bolts up, so I feel like there's a different term for them. If not I'm sure they are considered "semi float" , if not they are extremely close to it.

Its kind of the same concept as newer cars just old school. Instead the weight of the vehicle being exerted on the axle shaft, like on a rear semi float axle, the weight is on the spindle and pressure is on the ball joints. The old school part is that there's a few bearings that work together to do the same job as the newer one piece unit bearings, then the axle shaft goes through the hub.

The axles don't carry the weight of the vehicle. They are full float.

In response to the reaper. That’s actually what I was kind of thinking.

The axles don't carry the weight of the vehicle. They are full float.

But I guess I learned something new. And with that being said are all front axles from the k series like that?

One would think they would have to be, although I haven't seen every front axle ever used. But the very first thing the GM manual for the 8.5 front axle says is that it is a full floating design. I'll grab a pic of it when I get to work.

Ok now I’m curious

Front axles are full float, they have a spindle that carries the weight.

Sorry, second thing it says. Second paragraph:
