Wheel Hub / Carrier

Studs are 80 mm long, with a 35 mm thread length on the wheel side. Perfect for cars with wheel spacers up to 15mm thick.

These studs are made from Ti-6AL-4V alloy for extreme strength, and excellent rust
and corrosion resistance. Significantly lighter and stronger than steel, Ti6Al4V is ideal for
rotating parts. The studs are also vacuum coated for increased hardness and wear
resistance, and a sensational aspect
The bullet nose further makes for faster wheel changes, and a great look.

Check fitment for your specific vehicle (model, year, engine) before ordering. Confirm the axle position and wheel fixing arrangement against your vehicle before fitting.

What Is This Part?
This is a kit of components for renewing the wheel bearing and front hub together, rather than replacing the bearing alone. It combines the bearing and hub with a wheel-carrier-to-hub spacer, lock nut, four hub bolts and an additional component referenced below. These parts belong to the wheel-end assembly, where the rotating hub is supported within the wheel carrier. The kit contents should be checked against the repair requirements for your particular vehicle.

What Does This Part Do?

• Supports wheel rotation: The bearing supports the rotating hub within the wheel-end assembly.
• Provides the wheel mounting: The hub forms the central mounting interface for the wheel and brake disc.
• Renews associated hardware: The supplied spacer, nut and bolts accompany the bearing and hub during assembly renewal.
• Brings related parts together: The kit bundles the listed components for the same repair, allowing their fit and condition to be addressed together.

Why Replace This Part?
Replacement may be appropriate when inspection confirms bearing wear or damage together with deterioration of the hub or its bearing seating surface. Renewing the bearing alone may leave an underlying problem unresolved if the adjoining housing or hub fit is compromised. SKF recommends checking the housing and axle whenever wheel bearings are changed. 

Contamination, damaged sealing surfaces and incorrect installation can also contribute to premature bearing failure. If a previous replacement has become noisy again, investigate the mating surfaces and fitting method before installing another bearing. 

When to Replace This Part?

• Confirmed bearing noise: Growling or rumbling traced to the wheel bearing during diagnosis, rather than assumed from where the sound seems to originate. 
• Excessive movement: Measured hub or bearing endplay outside the vehicle manufacturer's specification. Wheel movement should prompt inspection of the complete assembly before selecting replacement parts. 
• Damaged hub seating: Wear, scoring or corrosion affecting the bearing fit.
• Distorted mounting surfaces: A damaged hub face or mounting area identified during inspection.
• Deteriorated fixings: Damaged threads, corrosion or other defects preventing correct assembly.

Where Is This Part Fitted?
Location: At the front wheel hub assembly on the applicable vehicle. The supplied front hub works with the wheel bearing at the wheel carrier, with the spacer and fixing components forming part of the associated mounting arrangement.
