94 rear solid axle size question

[Schurkey]

I'd expect that 2WD and 4WD 9.5" axle shafts are identical except for length.

Note that I've never had a 2WD 9.5" axle apart.

do you know if the 2wd 14 bolts have the same size axles as the 4x4 10 bolt? Pretty sure they are both 6 bolt pattern axles. Also if the splines are the same.

The 10 bolt and 14 bolt rear ends do not share common axle shafts. About the only thing you'll find the same would be the wheel lug pattern..

Alright thanks, do you know if they changed the length of the axle shaft throughout the years? Im still trying to figure out why it turned out short. They are both 10 bolt but one was a 88 and mine is a 94.

I thought we already discussed the axle shaft length issue to death right in the beginning of this thread?

Sorry i mustve missed one of your replies stating that the rear end mightve been swapped. Just to be clear any k1500 10 bolt from 90-98 should work as a replacement?

do c2500s have 6 lugs and same axle length of c1500 axle?

I thought C1500s had 5-lug axle shafts.

I'd expect a C2500 to have a 9.5", "14 bolt semi-float" axle in either 6 or 8 lugs, or an 8-lug 10.5", "14 bolt full-float" axle, where the 1500s have the craptastic 8.5" "10 bolt" axle.

I won't promise that the axle shaft length is the same between 8.5", 9.5" or 10.5" axle assemblies, even if the overall width is the same. In fact, I strongly doubt that the axle shafts are the same length among the three axles. The differential carrier is probably wider as the sizing goes up, leading to potentially shorter axle shafts for a given width and of course the full-float axle shafts are a whole different animal.

There are too many variables. Here's what I've gleaned, and it may or may not be correct.

Early 1500s came with 5-lug 10 bolts and later 1500s came with 6-lug 10 bolts, except that the 454SS trucks came with 5-lug semi-floating 14 bolts. Throw in that the four wheel drive 10-bolt rears were different widths and you now have 5 different rear axles, just for the half-ton trucks. The later 1500s had 6-lugs, and I think a 6-lug 14-bolt was an option on some of them.

Then you have the 2500 and 3500 trucks. The 2500s came with an eight-lug semi-floating-14 bolt while the 3500s had a full-floating 14 bolt, but you could also get a 2500 with the full-floater. I believe the 3500s were always full-floating, but then you also have commercial trucks with a narrowed full-floating axle. Do the four wheel drives have different widths on the larger trucks? I dunno. Don't forget that early 3500s had the Dana 70 which is an entirely different axle.

Dizzy yet?

In essence, @Jjbiskup, you're going to have to take a tape measure to your axle to get a measurement, and then you're going to have to get out your pirate map and try to find that buried treasure at the junkyard. If you can find a truck of the same year with the same drivetrain you might get the right axle. Fortunately, a '94 K1500 should be an easy find.

So my best bet would be to take my axle back out and measure it it seems.
