Spring suspension manufacturer maintenance recommendations include periodic checks of fastener torque values and usually include an initial re-torque after break-in. While regular preventative maintenance will keep the majority of spring suspensions rolling productively, there may come a time when a spring needs to be replaced.
Typically, a broken spring can be identified during a walk-around inspection. CVSA has out-of-service requirements for a spring assembly to identify an issue. These require replacement if:
• One-fourth or more of the leaves in any spring assembly are broken;
• Any leaf or portion of any leaf in any spring assembly is missing or separated; and/or
• There is any broken main leaf in a leaf spring.
Spring replacement is well within the capabilities of reputable trailer repair shops and within the scope of in-house work, as long as you have the right tools and training for your shop’s technicians. Safety, of course, is paramount.
