16 should be the thread count. If the shaft has been out for any amount of time I would run a tap through the holes first.

Found em. They're UNC (Unified Coarse), the ones I had were UNF (Unified Fine). Anyway all sorted now so thanks for the advise. Got the driveshaft on.

Next question!!!!...
Is there any way of telling if my locking hubs are engaging???

if both are lock your front shaft will be locked with the transfer case in neutral

So would I be able to tell by putting it in 4 HI, then put the transfer case in neutral, jack the front axle and try to rotate one of the wheels by hand. If it doesn't budge the hubs are locked???

Put your transfer case in neutral, lock the hubs, jack the front end up and turn the wheel. If the drive shaft turns then they are locked. Make sure the truck is not going to roll, too.

Or you can jack each wheel up separately. Lock the hub rotate the wheel. If the axles turns its engaged. Unlock the wheel should roll without turning the axle. Transfer case does not need to be in neutral.

If they are manual locking hubs just lock one and reach around the tire and try to rotate the axle.

the lock pushes a sleeve with spines on both sides inward and that in turn locks the wheel hub to the axle shaft. its more simple than most would think
thanks ej
it pretty much pushes 11 into 12

11 and 12 mesh together when locked, and 13 pushes 11 out when unlocked. 11 grabs the axle shaft, 12 grabs the hub.

Thirsty's way works too, but have had them have a bad spot in the hub. They could be locked in that postion, but partly, or completely disengaged in others.

Thanks, so presumably when the drive shaft rotates, by 4wd being engaged, it locks the hub.

its gets locked when you turn the dial. when you turn the dial, it pushes #12 in, which meshes with #11. #13 spring pushes #12 out when the hubs are unlocked. #11 is stationary.
