There aren’t many components on a modern truck that can trace their lineage back to horse-drawn carriages of the mid-1850s, but that’s the case with the fifth wheel, which was adapted for motor vehicles in the early 1900s.

These days it’s near impossible to imagine life without the ease of coupling and uncoupling, not to mention the stability and manoeuvrability afforded by this device. But as handy and ingenious as the fifth wheel is, it is not a set and forget component. Far from it, because the fifth wheel is the key point of contact between your rig and trailer, so bears the brunt of the loads you haul, day in and day out.

Performing basic regular maintenance will help ensure your truck’s fifth wheel remains in good and serviceable condition, and that your fleet continues to run at optimal efficiency.
