LOCKNUT - NYLON (Toyota TY0110311CE)

A damaged locknut can allow threaded fasteners to loosen under vibration, leading to mechanical misalignment or component separation. The Toyota catalog reference TY0110311CE identifies this part as an aftermarket replacement locknut with a nylon insert. This type of nut uses a nylon ring to create friction against the bolt threads, resisting loosening from shock or movement. A common failure consequence is that a worn or missing locknut may cause bolted joints to back off, resulting in rattling or detachment of attached hardware. During routine service, a locknut that spins freely without resistance indicates the nylon insert has degraded and should be replaced. Keeping a locknut in sound condition helps maintain clamp load on threaded connections over time. Verify the serial number or application, then call (562) 693-7748.
