I have a 14 Bolt rear axle from a 78 3/4 ton chevy 2wd and I am looking to find out if it is a Full FLoating axle or a Semi Floating axle. Does anyone know if there is a website that may help in identifing it?

The axle is currently at Home in Sac but im at College in SLO so I can not actually get to the axle for 2 months to find out.

I cannot believe you asked this question. Try a search :rolleyes: :rolleyes:

I have been searching for hours but I can not find any definate answers.

I have read the entire article. It mentions that there are semi floating axles but it does not specify any information on those. The most I was able to get out of that site was the fact that a full floating axle is offered for that vehicle. (Well and a few other good ideas about what to do with my axle)

since your cluelessness seems genuine i'll help you further. if your 14 bolt doesn't have a hub like this pic it would be a semi floater. the pic shows a full float axle. the search is your friend.

edit: the pic came with the pink line drawn...ignore it,it has no bearing on what you need to know.

thank you

I'll add to this a little because I get the feeling from your posts that you are new to this and sound like your willing to learn. I think you need to learn some basic mechanical knowledge before you jump into anything.

A full floating axle has a spindle that is part of the axle housing. The hub/brake drum turn on the spindle. The axle shaft takes the torque from the differential and carries it to the hub/brake drum and turns the wheel. For a full float axle the axle shaft itself only carries the torsional load.

A semifloat axle has the wheel bolted directly to the axle shaft. In this case there is one bearing pressed onto the shaft and the axle shaft carries both the vehicle weight AND the torsional load from the driveshaft.

In the pic posted above you can see 8 bolts that connect the axle shaft to the hub/brake. Remove those 8 bolts and the axle shaft will slide out, but the hub/drum will still be held in place by at least one nut and one keyed washer. On a lot of older 14 bolts there are two nuts, a keyed washer, and a lock ring. Remove these and the outer bearing, then the hub/drum assembly will come off and you'll be able to see the spindle underneath.

Good luck.

On the older 14B and the eatons the outer bearing doesn't come out from the outside. Both bearing come out from the inside. Just about every other full floater comes apart the way you said.

Just to add a little something, IF the axle hasn't been changed, it's a full floater. GM didn't use the semi floaters till 81. So, all 3/4 and 1 tons 80 and earlier used the full floater. Just FYI.

Thank you all very much, I have learned a great deal and my answer has been clearly answered :)

I KNEW i could count and all of you! :D

You're right. The '73 I made my rear axle from was that way. The '89 and 2001 I have have in my shop both come out from the outside.

I tryed not to reply but you realy need some one to build this truck for you. You should consentrate on school and become one of those rich basterds who pay people like me to brake my knuckles. You obviously need help. If you got the cash I can make anything work.

You are right, stay in school so you can learn to spell correctly! Don't even try to "biuld" things on your own, you will fawk it up. :rolleyes: :rolleyes:

Actually your right, I do need to focuss on school which is why my truck is sitting in Sacramento till the end of summer where my friend is doing the frame work and installing the new axles. When I get home for the summer I will finish the project.

Oh and please, who really uses proper grammer and spelling on the internet. 99% of Americans are too lazy to hit the spell check, do you?
