Default Front end tollerences...

Most of us, if not all, would like to have the front end assembly, when attached to the front cross member and measured from equal points, A to B, left and right, be almost equal.

However sometimes they are not equal.

In other words, pick a point on the front end (A) and measure to a "given" point (B) on the frame, left and right. They should be equal or darn near close to it but sometimes they are not.

With that said...Just how much of a tollerence is acceptable if one can not adjust the "problem", if in fact it is a problem, to get to where both sides are equal? 1/16"?, 2/16"?, 3/16"?

Thanks.

Pluck

Before trying to get that exact on the bumper measurement, put a bag of beans or something similar to 3/4 of the weight of the average weight of a 1929 adult male in the drivers seat. Common practice for alignment if going by the book.

Never heard of that before but it sure makes good sense. Thanks

If I'm making or pulling a frame I like it to be within 1/16"


When doing alignments If the vehicle is used mostly by one person I leave the pass door open. Of course for crowned roads I set camber and sometimes caster different on each side.
