Front Suspension Strut Mount Bearing for Nissan

This strut top bearing sits inside the upper mount of a MacPherson front suspension. It lets the spring and strut turn smoothly with the steering while carrying the vehicle’s weight. With a healthy bearing, steering is light, quiet, and precise, and road vibration is filtered before it reaches the body.

Why you need it

It reduces friction between the strut and mount, keeps alignment stable, and prevents stress on the shock piston rod. A good bearing protects tires from scrub, cuts steering effort, and keeps your front end silent on bumps.

How it works ⚙️

The unit uses hardened raceways and steel balls inside a sealed cage. It sits between the upper mount and spring seat. When you turn the wheel, the bearing carries axial load while allowing smooth rotation. Factory-grade grease and seals block dirt and water for long life.

What happens if it’s bad ❗

Expect heavy or notchy steering, spring “twang” when turning, clunks over speed bumps, and “memory steer” where the wheel won’t return to center. Left alone, it can crack the mount, twist the strut rod, wear tires unevenly, and loosen other suspension joints.
