Knuckle Hub Assembly

Preassembled, bolt-on wheel-end solutions designed to simplify replacement.

Bolt-on corner unit

Factory-assembled

No bearing press required

Reduced install labour

Engineering & quality

Well built — and proven at every stage.

Engineered around the application and verified through the program, from raw material to final inspection.

Knuckle + hub, integrated

The knuckle and hub come together as one factory-validated assembly — geometry and fit set before the part reaches the bay.

Reduced install time

Replace one preassembled unit instead of pressing the bearing and hub into the knuckle and sourcing multiple individual components.

Validated fit & geometry

Components matched and checked as a unit for accurate, repeatable installation.

ABS integration

ABS encoder/tone-ring and sensor configuration matched to the application, where equipped.

Checked and tested at every stage

Component production
Heat treatment
Machining
Assembly
Final testing

Material & heat treatment

Components made and hardened to specification.

Eddy-current testing

Components scanned for surface cracks and heat-treatment consistency.

Dimensional inspection

Critical dimensions verified by gauge and CMM.

Assembly fit & geometry

Corner validated as a unit for accurate fit.

Bearing preload & rotation

Preload and rotation verified to the application.

ABS signal check

Wheel-speed signal tested on ABS-equipped units.

Seal & grease

Sealing and lubrication checked.

Coating & corrosion

Surface finish inspected and salt-spray tested to specification.

Final inspection

Visual and functional check before packing.
Critical checks are performed on every unit; durability and corrosion testing are validated on a sampling basis to program requirements. Backed by IATF 16949 and/or ISO 9001 certified quality systems.
Made for your program

Built to your brand, not a catalog.

Protective Coatings & Surface Treatments

Bosda offers multiple surface finishing options to meet performance, durability, and environmental requirements across different applications:

Regular

Our standard finish provides reliable performance for general applications, delivering consistent quality and corrosion protection under normal operating conditions. 

Black Oxidized

Our black oxidized finish enhances surface protection while improving resistance to wear and light corrosion, with the added benefits of a uniform appearance and increased durability.

ECoated

E-coating offers superior corrosion resistance and long-term durability, especially in harsh environments. This advanced coating process ensures even coverage across complex surfaces.
