@independence31-2, Welcome to the VCCA's website!

I am moving your question to the technical forum for your year vehicle. I believe you'll get more 'eyes' on your topic there.

Cheers, Dean

I believe you will find that to adjust the camber on a straight axle you have to bend it. You can adjust caster with tapered shims between the spring and axle.

Hello Hans,

From what I've read, it appears that Dennis is correct that camber is changed and set by bending the axle. Cold bending seems to be recommended. Heat weakens  the metal. What model of Independence do you have Coach, Sedan, Roadster, Pick-up? Do you have a repair manual to reference alignment recommendations/specifications?

Edit: Chevrolet Repair Manual. Independence Model. Series AE-LT. Page 103 title: Straightening Front Axle "I" Beam

I won't copy word for word, but, this is the idea that is presented: Measurement is taken using the king pin angle by replacing king pins with guide pins centered in holes and extending upward (say 5") from both king pin holes. A predetermined angle tool is set down upon both leaf spring pads atop the i-beam to lay flat with the end of the tool having the proper angle matching the guide pin angle precisely. Do this for both ends to determine alignment issues. This method appears to be done with i-beam removed from vehicle. Here is the last sentence: "Remember to not heat Chevrolet front axles, straighten them cold." I don't believe this tool/gauge exists nowadays. Maybe you could make templates from both sides and compare identical angles or not to start with. Big truck repair shops do bending and may be of help to determine miss-alignment. Modern alignment shops may never have seen a straight axle before, but worth asking. Do you have steering issues or visible difference between both wheels when viewing from in front of vehicle?   

On my old ones with a straight axle I have found that camber was usually close and changing caster and toe in made them drive better. I have a caster camber gauge that has a magnet to go on hub. Also make sure there’s no extra play in the steering gear tir rod ends and king pins.
