I assembled my car after restoration and have a difference in the wheel base front to back of 1 inch, what could it be? The frame was square before I put the body on
I have never measured the wheelbase front and rear, it it could be normal.
Front radius rod bent on one side?
Rear axle radius rods bent or not adjusted evenly?
I would suspect Mark's answer "B"
Also make sure the front wheels are both pointing dead straight.
Front axle could have gotten turned around, that would possibly change the wheelbase if the perches weren't turned around accordingly. Check to see that the bosses on the perches are towards the rear. Jim
Front axel in wrong bent radiouse rods
Plus could been wear in every part you rebiult
Thanks guys for the advice I will let you know what I find. Happy New Year to all
If you don't have the front and rear axles supported by the radius rods, that can throw you off.
I found references (Vintage Ford & Ford Manual) to two (2) different measurements. One stated 99" while the other stated 100". I don't remember which was which.
You also didn't state if it grew or shrank. New bolts and bushings might explain a growth. Also rear radious rods out of their original position could cause either condition.
The wheelbase on my speedster grew when lowering the center of gravity. The angle of the drive shaft lessened this lengthening about 1/2" .
Craig, do you mean a 1" difference from left side to right side?
I never measured my Ts. Not sure of the source, specs I read long ago said WB is 100". A side to side difference isn't good, but a lot of Ts then and now "dog track" a little . . . "it don't hurt the runnin' of 'em none . . ."
Page 153 of The Model T Ford Owner by Murray Fahnestock, has a some measurements of the chassis. The wheel base is 99 inches on this diagram.
The Passenger side is 99!/2 the driver side is 98 1/2
Bent socket on oil pan or short radius rod to the rear axle, or possibly both
Might have a very rare trapezoid frame
