SD axles in an obs

Hey guys. I'm making my truck into a 4x4 dually. I'm picking up a box this weekend. My question now however is how much work is it to install SD front and rear axle housings in my truck? Will they bolt in? I'm not looking at a coil spring setup, but leaf spring. I have to get a dually axle and wheels anyway, so thought I'd see what is all involved in putting front and rears in. I also want to stay with 4.10 gears, not wanting 3.73's. I think you could get 4.10's in a SD dually, couldn't you?

I'll probably end up going the cheaper way with an axle out of an OBS dually and change the front hubs, but figured I'd find out what would be involved for sure. This probably won't take place until next year, I'm just gathering parts and ideas.

Thanks.

The rear is a direct bolt in.
The front will need to have a spring pad moved on the axel if you stay with leafs

What I don't like with the Superduty front axle is the unit bearing hubs on it. They are spendy to replace. On the plus side they are easy to replace.

Could you use an RSK and then bolt the axle up right underneath?

I think the E99s have a bearing/race setup like ours. May be hard to find specifically though.

Why avoid the coil setup for the front? It is a great improvement of the leaf setup.

Cost, and work involved. Not all of us can find a good deal like you did Richard! I'm not in this for the ride anyway, or shorter turning radius. It's a tow vehicle, not much else. Nothing wrong with a leaf spring axle.

Thanks Mike, I now remember the spring pad movement that needs to be done.

Tom, I forgot about that unit bearing deal. I may have to look into that more.

I'll check into that E99 deal Jacob. Thanks.

I'll probably still end up with the obs setup. It was early this morning and had a thought. You know how that goes. I'll do some more looking though.

Just my opinion here, but I think you'd be better off cost wise and labor involved to just swap in a D60 and dually rear axle, or find some GOOD steel spacers for the rear (not the aluminum ones), and keep your axle. That way if your ever have an issue like William just had, a single wheel axle will be a lot easier to find than a dually axle.

I might be willing to part with my axles... I am not sure I will ever get around to the install...depends on the offer coming across the table.

PM me what you all have and your thoughts on how much you want when you have time Richard. I'm assuming they have 3.73's? I may be interested. Thank you. I'd have to figure out how to send all the parts with Glenn to South Dakota! JK Glenn.

Thanks for the ideas Bill. My problem with a D60 around here is as much as I've looked the problem I have when I find one is the price. Everybody knows what a D60 is around here and demand a big price for it. Are the steel spacers as good of a deal as a true dually axle? I'd assume a guy could use them on a set of axles like Richard is talking about too? Does a guy just use stock diameter wheels then? I don't know much about spacers.

Thanks again guys.

I'd like to think you can put the outers from the 4x4 sd dually on the D60... I assume the 4x4SD Duallys used D60 axle up front. I have been looking but cant seem to figure it out.

I am not sure Glenn has enough room... the two axles plus the frame and springs took me two trips and that was with nothing in the bed and he has a 5th wheel hitch and a toolbox tank.

If I sell them it will have to be an all or nothing kinda deal.

Richard

Ya, I know Glenn wouldn't be able to haul them, I was kidding. I don't think I'm gonna go that way anyway. The more I look at those unit bearings and so on I think I'll just end up with the dually axle and hubs for the front of my D50 for now. I really don't think I like the idea of spacers. I'm not worried about finding an axle, could buy one right now if I had some more money put aside for this project. They aren't that hard to come by.

I would not do spacers. I like unit bearings but they do not react as well as the other type to spacers.

I wish I knew what axle the SD 4x4 DRW trucks used. They did not offer a wide track front axle in the 4x4 DRW config. Was there ever a D70 or D80 ever available for front axle?

You may PM strokersace about this. I'm pretty sure he did a 99-04 SD axle swap into an OBS.
