After a review of the options regarding repair vs. rebuild the decision is to rebuild, then a few additional considerations are necessary. First, rebuilding a spring is more involved than simply disassembling the unit, inserting a new leaf or leaves, and bolting the unit back together. Leaves can be replaced in one of three ways, using the same thickness steel as the broken leaf or leaves. These are:

While it may seem to be a minor issue, attention should be paid to the how the ends are finished on the original spring, with replacement leaves following these guidelines:

	Blunt (square cut) ends should be replaced with Blunt ends.
	Diamond Points (corners cut) and Rolled Ends (rounded corners) should be replaced with Diamond Points. (Rolled Ends are not commonly available to the replacement market).

Fitting versus Re-arching/Refitting

A Professional repair center will "Fit" the new leaves to the existing arch of the remaining leaves prior to assembly - hence the term Fitting. This operation is highly desirable and gives you more value for your repair dollar.

Re-arching/Refitting consists of bringing a Used spring back to original arch according to spec through either re-heat treating and re-forming the leaves, or, by cold re-arching via the use of a hydraulic press.

While re-arching is not an uncommon practice, its value as a viable repair alternative is questionable due to the fact that heat treating of spring steel is a delicate process requiring proper furnace temperatures and quenching techniques. Further, cold bending can cause Stress Risers in the steel which will accelerate the potential for failure.

The bottom line on spring repair is simply this: Utilize a professional spring repair facility for the repair, or consider a complete replacement. Why risk safety or additional downtime?
