Can possibly get a D60 and D70 very cheap, but I need to know a few things about them first.

They are both from a DRW truck, how hard and how much $$$ to make them work with regular wheels? I am wanting to stay about 83-85" to the outside of the tires.

Also, the front axle is a BALLJOINT D60, are they worth using? I know most people use the kingpin 60's. This would be under a Toyota with 4cyl, so not much weight at all.

Thanks

Hummer H1 double beadlocks have 7" of backspacing. An SRW D60 front is 69", DRW is about 78" if I remember. Since standard wheels are about 3.5" backspace, the H1 beadlocks make it about 7" narrower, for an effective width of 71". If you run a 14" wide tire, that makes you 85" wide.

Also, the balljoint 60 should be just fine on your rig. They are made to last on 1 ton trucks. The main advantage to the kingpin is the ease of mounting high steer and the cheap, easy rebuildability.
 
Theres a thread on Pirate about the conversion for the front hubs. Didn't look "that" difficult to change the DRW to SRW on the front, but you could always swap on some SRW hubs. I've "read" about people running the balljoint 60's with no real problems, but I'll let those with real world experience chime in. You could always throw some hummer wheels on there, and not mess with the hubs. Jim's got some for sale.....just a thought. If the price is right I'd say jump, but a 70 will be massive on your rig(maybe even overkill if there is such a thing).
 
Well I type too slow :). Yea the hummer wheels should be no problem, I've heard of some people having trouble with TRE interference, but I can't recall what set up and all they were using( just some thread I caught on Pirate.)
 
It depends on what make of D60 this is. If its a Ford, I'd just switch it to SRW. It's cheap and easy. If it's a Chevy or Dodge... the decision-making process is a bit more difficult, just because new hubs are more expensive.

You're also going to be skinny in the rear, since most dually rears are 63-70" wide, depending on chassis. You'll be ... something like 7-10" narrower in the back.
 
ok, so I can't use the D70 rear then, no big deal. As for the 60 front, if I ran hummer beadlocks, the hub itself would stick outside the wheel pretty far then probably, so converting to SRW hubs would be a must. It is a Ford axle as well, what would be involved in switching to SRW?

Thanks
 
Actually the hub shouldn't stick out of the wheel much at all. Try and find some pictures online and you will see what I am talking about. The dually adapter is a big metal piece that bolts on and essentially encloses the locking hub portion like a pipe over it.

i think that was with the srw setup. pretty sure parts mike makes arms that work with the stock hummers though.

Look at pics of StudNuts' old buggy - he was running DRW front with stock BS Hummer wheels, it didn't stick out AT ALL.

Supposedly you can use the hubs off a F250 with a D50 TTB. There is more to it than that though. Saf-t probably knows the details.

You could probably use a van 14 bolt to help even out the width front/back if you used the stock Hummer wheels on the DRW front hubs.
 
All things considered if i had to do it again i would 'try' to run the DRW hubs.

I have a good bit of time/money in my wheels and recenter plates etc.. With a drive flange (on the DRW setup) i think its about even with the stock H1 wheel..

The WFO arms I have will clear either wheel offset.

ya and the van axle is wider so that might work...

Yeah, they're exactly the same. There are some variations in brake hardware from year to year, so it's prudent to verify exactly what you have... but I put a D50 TTB hub on a D60. Brake hardware was all the same, rotors and everything.
 
im sure you already know, but depending on the yr model or the D60 & if its a ford, it might have a different lug pattern, and the hummer wheels want fit, prob not an issue but since it is a ball joint axle i thought there might be a possibility of that, just wanted to through that out there cause i know how easy it is to forget about the small stuff.
 
Well, I found an axle (again). It is a SRW axle out of an 88' truck (I think). BUT it is missing a few things:

Lower kingpins, 1 spindle, brake calipers, rotors, inner axles, bearings, U-joints.

I have a friend with a D50 TTB out of a 97' F-250. What all will interchange if anything?

Also, where can I get 30 spline drive flanges, or should I just search junkyards for trucks w/o manual hubs?

Not a lot. Calipers and rotors might swap. You'll have to check part numbers. Hubs probably swap. That would be all. Spindles will technically work in a pinch, but the boss isn't long enough to properly support it in the knuckle.

You don't want anything to do with 30 spline stubs. They break and take out the spindles. You'll end up having to cut the hub to get the busted spindle off of the knuckle.
 
hummer wheels would work well in the front. will make the rear a little narrow. you could run wheel spacers in the rear to even it out a little.
Or... you could have the DRW hubs machined down to SRW width. A buddy here in town had his done. Looked gooo, plus you keep the Beef of the DRW "pipe" out protectong the hub.
Or buy some srw hubs.
Give me a call sometime i've gor a hp 60 front, complete and a built 60 rear w/discs. i'll PM my number. dave
