Spindle design

[NOBLNG]

I see in most pictures that the "C" shaped kingpin bracket is welded to the frame, and the spindle and steering arm are welded to the kingpin tube. Is there any advantage to this over welding the kingpin tube to the frame (at the proper angles) and attaching the spindle to the "C"?

I think so......by reversing that it takes more leverage to turn the wheels.....and therefore multiplies the effects of rutts, bumps,ect.....as well....

There is a lot of information on how to set up the correct Ackerman, castor, and camber the normal way....but you would be on your own turning that around....

Also, I think it would put more stress on the steering linkage....

Usually with the C bracket welded to the frame or front axle would keep the pivot closer to the wheel center line which makes it a little easier to steer also I think the spindle shaft welded to king pin tube rather then the side of C bracket is a little stronger arrangement but ether way does work

Thanks, that makes perfect sense now that I think about it. It would indeed greatly increase the tire's leverage over the steering linkage. Back to the old drawing board!

apart from the above...

simple spindles do not run on bearings not even bushings sometimes.. so the TUBE will be the part that gets eaten away by the kingpin..

having it on the frame requires welding for replacement; having it on the spindle is much easier to fix (aka buy a new spindle)
