Nissan Xterra Leaf Springs

The leaf springs underpinning the chassis of your Nissan Xterra are very simple, tough, and inexpensive components invented centuries ago. But even today, this kind of a mechanical spring is widely used in large 4x4s and commercial vehicles. Working in tandem with shocks absorbers, the leaf springs form a flexible foundation allowing some limited motion between the chassis and the wheels. Although the leaf springs are enormously durable, they are still susceptible to weakening and phenomenon known as the metal fatigue.

With age, constantly bending metal loses its characteristics getting softer and softer. The resultant sag of the body warns that the springs approach the end of their service life. Concurrently, the leaves accumulate microscopic cracks – that’s what the metal fatigue is. Not dangerous at the beginning, those cracks grow, further weakening the structure and transforming springs into a ticking bomb. If not replaced, such leaves simply fail one day, when the cracks are big enough to cut the metal strip. What makes it especially dangerous is that failure always happens at the peak load – at speed, with cargo or passengers. Hence, don’t wait for too long having noticed the sagged back of your SUV, order and install our Nissan Xterra leaf springs & components.
