I'm building... a thing. About 800lbs loaded and occupied. Powered by 2 12HP electric motors(front) and a 70HP motorcycle engine(rear). 22.5" tires.

I need something to hold the front wheels apart, steer, drive, and weld to. No wheel suspension. The cab will be suspended but 3 wheels remain in the same plane relative to the chassis.
Recommend a lightweight solid steering axle housing and all the bits from wheel flange to 5 on 4.5" wheel flange excluding the center section. So really, tubes, knuckles, bearings, hubs, some type of outboard CV, and axles. Tubes will be shortened and center section replaced by inboard electric motors, planetary gears, and brakes.

Basically any castaway undesirable front end like a Dana 25 will do, but I want it as light as possible and with the greatest steering angle possible. Is there anything lighter than Sami stock housings? Did any ATV/UTV ever come with solid axles?
Perhaps an AWD rally or drift car part? Sprint car? Maybe weld a cage to ball joints and use the uprights from wishbone suspension without the wishbones? The loads this will see are very small compared to any passenger vehicle.

Hoping to see links that help me visualize different ways to do this.

There are not many of these out there. But the Honda TRX 350 had a “solid” front axle.

Or you can get to cutting and welding and build a steer axle from a solid golf cart axle like I did..... (some assembly required)

The “Bad Boy Buggy” golf cart had one like the Honda 350, but they were cheesy with no bushings or ball joints and the bolts would eat the knuckles apart as you steered....

Thanks, the pictures help me get a sense of scale for the size of parts needed to handle less than truck weight. Not much different. Except for those U joints on the stub axles. What size are they and did they hold up? They look really small compared to the lug studs. Like steering shaft size.

They are the steering shaft u-joints... I’m just installing it now. I think they will be fine. My son’s mini Jeep only weights just over 400 pounds.

I'm loving that plywood Jeep body. I wonder how well that would work on a real trail truck? Bash a panel, route another one on a Maslow and be out again in minutes for the cost of a quarter sheet of plywood. I wouldn't even paint it.
I considered using some quality steering U joints then figured that they need to have little or no backlash so steering feels tight. I thought that might cause excess heating and breakage in a continuous application. But that was just speculation. I'd like to hear how they are doing after accumulating miles.

It’ll be a little while before it starts accumulating more miles... I’m updating the rear suspension to an4 link also and it’s been single digit temps here, so it’ll be a while before I can even paint my parts and do final assembly.

Just Google :
Ford tractor 1715 4x4

I think they were all full width straight axle.


If you need 5x4.5 hubs with the standard 1/2x20 :


The 3910 might be beefier then you want.

I have never used or even seen these in person, but, this smaller thing might be better suited for you.

2005 Kubota GR2100 AWD

I decided to go all hydraulic for my 6x6, so, I did not keep up on the smaller stuff.
