wheelbase
what is the right way to figure wheelbase?
axle nut of the steer to axle nut of the last axle on my wrecker it is 25'' and when I scale up I get 29'2'' or 350'' im thinking I could go longer for the wrecker |

Re: wheelbase
Thats the way I would work it out ctr front axle to ctr rear axle
As over all length would be front of the vehicle to rear of the vehicle Cheers Tracy

Re: wheelbase
I could be wrong but I think it is measured from the front axle to the center on the tandems(trunion). That's the way it was measured on the 850 KW's anyway. I thought it was measured from the front to rearmost axle and had to redo my frame length twice because it was too short!lol

Re: wheelbase
Reg is correct, steer axle center line to rear suspension centerline.

Re: wheelbase
The lift axle wont make a diference it is to the center of the drive axle or axles.

Re: wheelbase
I could be wrong but I think you measure a wheel base from the center of the front axle to the center of the rear most axle. Ed

Center of steer to center of tandems. If it were tri drive? I'm not sure. But likely still center of rear two axles.

Re: wheelbase

OK......so what is the difference ? they talk about wheelbase but mean axle spacing ?! even more confusing !? |

Re: wheelbase
In the manufacturing arena, axle spacing would be the distance between the center line of the drive axles in the case of a truck and the "spread" of the axles on a multiple axle trailer. If you've heard of a trailer suspension referred to as a three nine, that just means 3 axles 9 feet apart. This used to be popular with steel haulers.
As far as what the DOT does...... well that's a whole new ball game |

Re: wheelbase
There is a kind of explanation on the model magazine forum, scroll down 1/3
and look at the picture. http://www.modelcarsmag.com/forums/t...bius-lonestar/ It's funny to see that nobody or everybody knows what is the right or wrong method is And DOT in each country does not make it easier either exception is lurking around. |

The wheel base is always measured to the center of the main drive axle suspension. |
