I'm glad someone sees my madness through the picture there I kinda figured if i drew it out, it would be a slight bit more imaginable.

What would you use for universial joints in the front axel? When I was considering this topic I thought of uni joints out of a car steering columb. Don't know how you would join them to the axel though - weld maybe, you would have to be a good welder and have a good rig to make sure it was straight. Or you could make your own uni-joints, If someone designs a good one they could post it up for others to copy maybe?? same for the spindles

Great idea though, I want to do it bigsmile

As for u joints, you can buy U joints that will fit over a 1" axle and lock in with a set screw. The knucles are what i think will be the trick.

This is my old rear axle with differential



So I can just cut the axle and slip those uni joints over them - awsome

I agree about the steering knuckles being hard, i still reckon it's doable though

It may take some looking around, but i know you can buy u joints to fit over 1" and 3/4" shafts. Steering joints off a car are 3/4" i believe. They would work well, only difference being they wouldnt fit over a round axle. The axle would have to have a flat spot on it, thats how it locks onto the axle.

After you come off the u joint with the shorter "wheel axle", you could put a bearing, then build a casing around the bearing for your knuckle.

So something like this is what we are suggesting? Please excuse the shoddy paint skills lol


You can add a diff, auctally i think it would be a must like the axle from my previous post

Lol you got to it before me, shows I'm a bit slow with the old paint, yours has better detail Phil
Posted on: 26-08-2007, 00:22:41
Phil the only thing I would add to yours is that I think i would 'stack' the spindles. So put both Blue bits under the Black bits (assuming they are two separate parts and not a big tube which the axle is housed in) to help carry the load. Like this one (from 4WD) -



and I would also add a bearing before the universal joint to position the axle and take the strain of the chain.

sounds good to me. My spindle setup was bassed on my T-drive setup posted earlier, so i wouldnt need the additional bearings (i dont believe).

You can get the CV/UV joint at www.surpluscenter.com they're around the 30-50 mark, and they have various models rated by the amount of HP they're able to handle.

I knew i seen some somewhere.

Those would be best for the 1" axle, the hp rating is good for what most of us would use.

The lower HP rated ones would even suffice, because remember, if you'd doing 4WD you're splitting the HP load into 4 tires, so theoretically you'd only need 1/4th of the rated HP of you're engine if you were running both F&R locked axles, 1/3 if you're running a locked rear and unlocked front, and 1/2 if you're running both F&R unlocked.

For my recovery mower (if I ever get to start that project!!!) I might be using 6 of the 28HP ones depending on how I decide to do the drivetrain badgrin

I think im gonna copy your recovery mower idea Chris, I got a 18horse opp. twin waiting for a job...

Ok i snapped some pictures of the front end on my 4wheeler to help clear things up instead of paint drawings.  Sorry its a little dirty, you really know you need to clean somthing when you have grass growing out of accumulated mud.

Would it be a custom jobbie? or just a transplant from a wrecked ATV
