4X2 Hub Conversion questions

[oneluckypops]

Ok gang, my truck has a fulltime front axle in it. As most are aware I am running a NP241C Transfercase. I am wanting to get a set of lock out hubs put on this. I had 1 other full time truck that i put hubs on and I know the warn 9072 part number is the 1 i need, BUT the cheapest I have found is 192.00, I am looking for alternative ideas, such as mile marker. I looked on there website but couldnt come up with any information as to them having the external bolt on hubs.

I really want to get this takin care of before I make the drive to get the parts from hotrodpc, so any information or ideas would be appreciated.

Warn #20990 for 77-87 3/4 ton chevys are closer to $100. If it's a 10-bolt I'm not sure what the real difference would be between the 1/2 and 3/4 tons. #9072 says it's for 60-76, Dana 44 possibly? If it's for the K30/ D60 model #38826 price is through the roof. I guess really we need to know what front axle it is, since the 20990 would be a lot cheaper if it's 10-bolt.

well the truck is an 85 K30 it should have a Dana 60 in it. BUT someone already swapped a Dana 44 into it.

If you dont really want to do high-dollar right now Rugged Ridge brand hubs might be more in the ballpark...

I dont have experience with them to really give any feedback but it would get you by.

These stainless steel MMs look great but I see it requires a spindle nut conversion kit or something...

Here's a cheaper verson of the MM with a plastic knob...
http://www.shopatron.com/products/p...rt_number=302/4888.0.1.1.58687.0.0.0.0?pp=12&

That should give you a few options and model#s to google.

I thought about swapping the knuckles from a 10 bolt taht already has the hubs in it, But dont know if the Knuckles will interchagne between the 10 bolt and Dana 44

Is it external because the spindle nuts haven't been converted? Or because it has bud wheels? (Not sure if it has bud wheels or not) My D60 has internal hubs, I reused them from when it was DRW to the SRW swap.

Here's a set of D44 external hubs that wont entirely break the bank... http://completeoffroad.com/i-123158-warn-premium-locking-hubs-dana-44-wrn20990.html

thanks I will check into them more tommorow when I have more time.

BTW Pops, if you would, whatever you decided to do here, Take some pics of what you have now, and do us a write up if you would. I'll be in the same boat soon. When I get that 14b FF 4.10 axle in the K10 frame, I have a feeling I'll have better luck finding a 3/4 ton D44 with 4.10's already set up and likley to be a 76 or earlier truck that had a NP203 will full timers on it and it'll need converted too. Or, I guess I could have as much of a chance to find a 10bolt from a 3/4 ton with 4.10's too. Being I need to convert to 8 lug, and 4.10's I think it'll be easier to find a 3/4 ton front axle.

It's external because they are the '73-'77 K20 hubs. The spindle nut conversion only applies if you are replacing the factory automatic locking hubs (like with the 208/241).

I have the stainless MM hubs on my K30 and they are great. They work nicer than the Warns, IMHO.

As for swapping the hubs, it shouldn't be much trouble. You just need the 8-lug stuff from a later 10 bolt, the hubs, bearings, and the spindles. Your stock knuckles can remain, as well as the caliper brackets, calipers, and I think the rotors too.

That's the info I was trying to think of how to spit out. I'm sure he has an axle that originally came out of a full time NP203 transfer case truck. And what else bucket is saying, if I understand correctly, is 10 Bolt and D44 Hub parts are interchangeable.
What did you do with the axle that was in your 79 with the NP205? Those hubs should fit this D44??? Frankenstein it.

the 10 bolt and D44 stuff is the same stuff, when it's the same year range. The biggest difference it the early K20 external hubs and their different bearings. We've discussed it before, but I think the spindles are different too, if equipped with external hubs.

6-lug stuff is the same, and all knuckles are the same. For example, I had two '77 Blazers at the same time. One was a D44, the other is a 10bolt and all the outer parts were the same. I also pulled the driverside knuckle from my Burb's original 10 bolt (6-lug) and gave it to a guy that installed it on his 8-lug D44.

Right, but 8 lug stuff is the same too right? So you can take 6 lug off D44 and put on a 6 lug 10 bolt, and vice versa, and you can also do 8 lug D44 to 10 bolt 8 lug and vice versa right?
So what all has to be changed if I have a 6 bolt hub, then I put a 14b FF in the rear and want to convert the front to 8 lug? More than just the rotor I do beleive.
Not that it matters to me much, my 6 lug is 3.08 and I want a 4.10 8 lug and most 8 lugs are 4.10 so I think that is my best way out. Find an 8 lug 10b or D44. And I'll find a spare too. After seeing prices for D60, and D60 parts, I think I can break and buy several 10b and D44's and still be ahead of the game, along with more ground clearance.
