The wheel hub hex nut secures the hub assembly in position and helps maintain the correct clamping force on the related wheel hub and bearing components. A correctly fitted hub nut is essential for safe wheel rotation, bearing support, and reliable road wheel location.

Functions
•  Replaces the wheel hub retaining hex nut
•  Helps secure the wheel hub assembly
•  Supports correct wheel bearing and hub clamping
•  Helps maintain safe wheel and brake assembly location
•  Used during wheel bearing, hub, brake, and suspension service
•  Replaces worn, damaged, rounded, corroded, or previously removed hub nuts
•  OE Match replacement for Porsche hub assembly repair.

Why Replace This Part?
Wheel hub nuts are highly loaded fastening components and may be damaged during removal, become corroded, lose correct locking integrity, or show thread wear over time. Reusing a worn or damaged hub nut can affect correct hub clamping and may compromise wheel bearing service work. Replacement is recommended when the hub nut is removed during repair or when its condition is in doubt.

When to Replace This Part
•   The wheel hub or wheel bearing is being replaced
•   The hub nut has been removed during service
•   The original nut is rounded, corroded, damaged, or worn
•   Thread condition is poor or uncertain
•   Brake disc, hub, or suspension work requires hub nut removal
•   The vehicle is undergoing Porsche brake, hub, or suspension restoration.

Where it fits on the car
This hex nut fits on the wheel hub assembly. Fitment position can depend on model and axle layout, so the vehicle parts diagram should be checked before ordering and installation.
