Hub Bearing Lock Nut Assembly for Nissan/Infiniti

This small but vital fastener secures the wheel hub bearing preload so your wheel runs true and safe. It keeps the bearing torqued to spec, prevents play, and protects the axle shaft, brakes, and ABS tone ring.

Why you need it

Install a fresh lock nut whenever servicing hubs, replacing bearings, or removing the driveshaft. New threads and the integrated locking feature stop torque loss from heat, vibration, and road shock.

How it works

After the bearing is seated, the nut is torqued to factory spec and then staked or locked. It clamps the inner races to the hub, sets preload, and maintains alignment. Quality steel with anti-corrosion finish holds clamp load for long service life.

If it’s worn or damaged ⚠️

Watch for wheel wobble, humming or growling, wandering steering, uneven pad wear, ABS warnings, hot hub, or metallic dust near threads. Driving like this can ruin the bearing, strip splines, or in extreme cases cause wheel separation.

Pro tips ✅

• Always use a new lock nut; never re-stake an old one.
• Clean and inspect threads; lightly oil only if the manual specifies.
• Torque in steps and align the lock exactly as designed.
