Its castellated design allows the nut to be secured with a locking pin, helping prevent loosening during vehicle operation.
What Does It Do?
The castle nut secures the rear wheel hub to the axle, maintaining the correct fastening of the hub assembly.
Its slots accommodate a locking pin, providing a mechanical safeguard against the nut loosening.
Why Does It Fail?
Common causes include:
- Damaged or stripped threads
- Corrosion and age-related deterioration
- Incorrect tightening
- Damage during removal or installation
- Repeated servicing and wear
When Should It Be Replaced?
Replace if the nut has damaged threads, excessive corrosion, deformation or worn locking slots.
Inspection is recommended whenever the rear hub or axle assembly is dismantled.

Tighten to the specified Porsche workshop torque and secure using the correct locking pin. Never reuse a damaged locking pin or nut.
