Front Wheel Hub 40mm
OE Match 40mm front wheel hub for Porsche
356C, early 911 and 912 models. Designed as a replacement for worn, damaged or
corroded original hubs, this component provides the mounting point for the
front wheel and brake assembly while supporting the wheel bearings.
Fits:
- Porsche 356 C 1964-1965
- Porsche 911 (with VIN F >> 030 5100) 1965-67
- Porsche 912 Coupé (with VIN F >> 035 4000) 1965-67
- Porsche 912 Coupé (with VIN F >> 0458 100) 1965-67
Diagram ref no 8
The front wheel hub is an essential part of the vehicle's front axle assembly, allowing the wheel to rotate smoothly while maintaining secure attachment to the suspension and braking system.
Manufactured as an OE-style replacement, this 40mm hub is ideal for classic Porsche maintenance, front axle repairs and restoration projects.
What Does the Front Wheel Hub Do?
The front wheel hub connects the road wheel and brake assembly to the front axle through the wheel bearings.
It provides a secure mounting surface for the wheel and brake disc while allowing the assembly to rotate smoothly around the stationary stub axle.
A correctly functioning hub is important for maintaining wheel alignment, consistent braking performance and predictable steering response.
Why Does It Fail?
Front wheel hubs are designed to withstand considerable loads, but damage or wear can develop over time.
Common causes include:
- Worn or incorrectly adjusted wheel bearings
- Corrosion around bearing mounting surfaces
- Damage from potholes or heavy impacts
- Distortion caused by accident damage
- Wear to wheel stud mounting holes
- Incorrect bearing installation
- Damage during previous repairs
- General age-related deterioration
A damaged hub can affect the correct seating of the wheel bearings, brake disc and wheel assembly.
When Should It Be Replaced?
Replacement should be considered if:
- The hub is cracked, bent or visibly damaged
- Bearing mounting surfaces are worn or scored
- Wheel stud holes are damaged
- Excessive corrosion is present
- The hub has been distorted by an impact
- The wheel or brake disc cannot be correctly mounted
- The original hub is unsuitable for reuse during a front axle rebuild
Excessive wheel movement, vibration or bearing noise may indicate a problem with the hub assembly, although these symptoms can also result from worn wheel bearings or other suspension components.
Checks During Replacement
When replacing the front wheel hub, also
inspect:
- Inner and outer front wheel bearings
- Wheel bearing races
- Front stub axle
- Wheel studs and retaining nuts
- Brake discs
- Bearing seals
- Hub grease cap
- Bearing retaining and adjustment hardware
Wheel bearings should be inspected, correctly lubricated and adjusted to the manufacturer's specifications during installation.
Porsche 356C / 911 / 912 Front Wheel Hubs & Bearing Components
The front wheel hub is a critical component of the classic Porsche front axle assembly. It supports the wheel and brake disc while working with the wheel bearings to provide smooth rotation and secure wheel mounting.
On older Porsche 356C, 911 and 912 models, wheel hubs can become damaged through corrosion, worn bearings, incorrect installation or heavy impacts. Damage to the hub or its bearing mounting surfaces can affect wheel rotation, braking consistency and steering stability.
OE Match 90134106509 provides a 40mm replacement front wheel hub for selected Porsche 356C and early 911/912 models. It is particularly suitable for front suspension repairs, wheel bearing refurbishment and classic Porsche restoration projects.Related reference numbers

What Does a Wheel Hub Stud Do?
Each wheel stud passes through the hub and provides a strong threaded fixing for the wheel nut.
When the wheel nuts are correctly tightened, the studs provide the clamping force required to securely hold the wheel against the hub.
A correctly functioning wheel stud helps:
- Secure the wheel to the hub
- Provide the mounting thread for the wheel nut
- Maintain correct wheel clamping force
- Allow safe wheel installation and removal
- Keep the wheel correctly seated against the hub
Why Do Wheel Hub Studs Fail?
Wheel studs are strong components but can become damaged through repeated wheel removal, incorrect tightening or corrosion.
Common causes include:
- Damaged or stripped threads
- Cross-threaded wheel nuts
- Excessive wheel nut torque
- Corrosion Impact damage
- Incorrect wheel installation
- Repeated use of unsuitable tools
- General wear from frequent wheel changes
Using an impact wrench incorrectly or overtightening wheel nuts can stretch or damage the stud and its threads.
When Should a Wheel Stud Be Replaced?
Replacement should be considered if:
- Threads are stripped or damaged
- A wheel nut will not tighten correctly
- The stud is bent or distorted
- Heavy corrosion is present
- The stud has been cross-threaded
- A stud has broken
- The stud is loose within the hub
- Damage is discovered during wheel or brake servicing
A damaged wheel stud should not be reused, as correct wheel clamping depends on the condition of both the stud and wheel nut.
Important Wheel Mounting Checks
When replacing a wheel stud, inspect the wheel nut and hub for corresponding damage.
Wheel nuts should thread smoothly onto the studs by hand before final tightening. Always tighten wheel nuts to the correct specified torque.
If several studs show similar corrosion or thread damage, inspect the remaining studs and consider replacing any that are no longer serviceable.
Wheel Studs
Wheel studs are an essential part of the wheel and hub assembly on many classic and modern-classic Porsche models.
Although designed for long service life, repeated wheel removal, corrosion, cross-threading and excessive tightening can eventually damage the threads or weaken the stud.
When carrying out wheel, brake or hub maintenance, each stud should be inspected for damaged threads, corrosion or distortion. Replacing defective studs helps ensure the wheel can be correctly and securely mounted.
