14 bolt question
How do you tell the difference in a full floater or semi floater?

Re: 14 bolt question
Full floater has axles that bolt to the hub from the outside. Semi the axles go in like a 1/2 ton.

Re: 14 bolt question
A full floater that I'm aware of has a very distinctive hub where the axle flange actually bolts in from the outside, and the drum assembly rides on a set of bearings, hence a floating axle. Will also have an 8 lug setup and rather large drums. At least my 1 ton 14 bolt does.
I'm not totally familiar with the semi float 14 bolt but I believe it wouldn't have any of the features I listed above, smaller brakes/drums, and the axle actually rides on a bearing like a conventional rear and uses C-clips to retain it. The ones I've seen have also been 6 lug, but may not always be. |

Re: 14 bolt question
Mines a 8 lug but i don't know if it's a c20 or 30. Anyway to tell that? It's In a crew cab but I think the PO said the rear end was out of a 3/4 suburban

Re: 14 bolt question
full floater = 8 lug
semi-floater = 5 or 6 lugs You can find a 14 bolt semi- floater in the 454SS pickups. RIZ |

Re: 14 bolt question
the semi floater 14 bolt [9.5"] 8 bolt is common in 80s suburbans and 3/4 pickups too. not all 8 lug are full floater. easiest way as said above is check the bolt on axles.. dead giveaway..
neat little video on full floaters |

Re: 14 bolt question
First 2 - 14 bolt Full Float - 8 lugs Only
The full float also has a removable pinion (bolts at yoke), where as the semi-float does not.

Re: 14 bolt question
I want one for my K5 too. So hard to find around here. I'd love to get one and put 4:56 gears in both for my new 35's.

Re: 14 bolt question
This might be the same video Speedmachine was trying to post. This is a great video explaining full-floating rear axles. The video is from 1936! The basic design is still the same today.
It floats
