Spring Service



Leaf Spring Diagnosistruck maintenance services

  • By disassembling your spring pack and visually inspecting the leaf spring, our spring specialists can identify degradation of steel (pitting), cracks, or broken leaves.
  • For springs submitted for bench repair (non-installed springs), free arch measurements can be taken and compared to the manufacturer free arch specification.
  • Inspecting the vehicle’s ride height is a critical component to determining potential leaf spring issues.
  • Over-loading (insufficient weight capacity) and uneven weight distribution can cause a vehicle to sag or lean.
  • Condition of the spring bushings, general age of the spring & condition of the leaves are all taken into consideration when determining if the integrity level of your spring has been compromised.
  • After all elements are considered; solutions can be offered to fix ride height and/or weight capacity issues.

Leaf Spring Arching (re-arch/de-arch)-

  • Arching leaf springs is a process or re-curving each individual leaf to a specific contour and free arch.
  • Vehicle ride height is determined by the arch of the leaf spring combined with the rate of the spring steel.
  • Modifying the arch will increase or decrease the ride height of the vehicle.
  • If a vehicle has a different ride height, either left to right or front to back, arching the springs can provide a solution.
