This is probally a stupid question but i need to know in a hurry and cant run to the shop right now. On a GM 10 bolt front differential can i swap 4.10 gears from a 3/4 ton to my 1/2 ton? are the bearings, gears, housing, everything the same? I am looking to just drop the 3/4 ton carrier and all into my axle, will it work?

Again i know this is probally mundane for you guys but chevys are new to me. I used to be a Ford guy!!!
 
They are interchangeable...

Probably be easier/cheaper to swap the axle housing out and put your outer stuff on it to make it 6 lug. You'll already have the axle and brake stuff already tore down anyways.. not too much work to swap the housing in beyond that.

Removing the gears and setting them up in the new housing will be a ton more work than just changing from 8 to 6 lug.
 
Agreed just change the outers unless something is wrong with the housing to prevent that.
 
Agree with the above regarding swapping the entire axle and converting it back to 6-lug versus swapping just carriers/gears.

There is no difference between the gears and carriers of a 1/2 vs. 3/4 ton 10-bolt. The only difference is the 3/4 ton has 8 lug wheel hubs, rotors, and different (taller) brake caliper mounts but they are all interchangeable.

The only difference to look for with the gears and carriers of 10-bolts are the years, as around '89 they switched from 28-spline to 30-spline shafts. Again, everything is interchangeable.....if you have a 28-spline carrier you need 28-spline shaft, etc...

Solved the problem. Found a 10 bolt with 4.10s and a lockright out in the back of the shop after moving some other axles:D. thanks for the help:bow:
