Broken Spring
 

I never noticed the front was cracked until I took it apart. I was surprised at how little tension there was and then I found several cracked. Strangely enough all the broken ones are replacements (i.e. have the square ends). Anyone ever experience the replacements break but the originals are still good?

Personnaly I have no experience, but I know someone who had 2x broken front springs in 1 year ! Don't know if they where originals or repro.

Either the arch was wrong, improper spring material in the first place, or someone didnt have the spring to fame u bolts tight enough.

Ive had plenty of broken ford springs. Usually the main leaf with the eyes.

A lot of the square ended replacements came from JC Whitney back in the day. I could see where they might have a different flex pattern and metallurgy as compared to the original Ford spring leaves. After thousands of flex cycles they might not be working together so well as a mixed assembly.

I have not experienced this with a Model A, but some 50 plus years ago I used to transport my racing motorcycles in a 1960 Ford (UK) Thames van. It was typically overloaded and driven far too fast. I had to make a series of repairs to the rear springs, each of which failed rapidly. Usually the failure was breaking of the replacement leaves, I finally replaced both springs with totally new material. Never had another problem. I have no explanation what was going on.

Thanks for the feedback - sounds like I should just replace the whole thing

Weird, I wonder if it has to do with one is being made into a specific part designed to carry a specific load (spring pack) so it may follow a very specific recipe to the steel and temper while the add a leaf or single leaf is a generic spring steel recipie. Im guessing they snapped right at the center hole?

All of the the original leaves, squatted out and useless, now replacement wrong leaves doing all the work.
