full time to part time axle interchange ?
 

I have a 85 GMC with 10 bolt rears I bought a set of rears with 4.56 gears thr rear is a 14 bolt and will go right in the front is a 10 bolt (8lug) only question is these were from a full time truck so the font does not have hubs can I just put hubs in it ? does not look like they will fit ??? I did get the correct crossover rear u joint.

anyone know about this stuff?

10 bolt hubs
 

The 10 bolt front hubs that I've seen are all the same, 1/2 & 3/4 ton. Some of the full time 3/4 tons front axles were a Dana HD44, they have 6, 3/8 bolts holding the end cap. This cap can be replaced with the large Spicer hubs. Do you have pics of the axle & hubs?

yes !! mine have the 6 bolt end caps !!! where would one go to find hubs to fit it?
Thanks

Spicer hubs
 

I don't know about where you live, but in my area they are a wrecking yard item. Most adds I seen want to sell rotors with hubs for $250. 4x4 parts places have brand new replacements. Good luck!
