Steering Knuckle And Hub Assemblies
A steering knuckle connects the wheel-end assembly with the suspension and steering linkage on a front steering application. Some listed rear knuckle assemblies serve the rear wheel-end location, where the mounting and brake arrangement can differ.
A-Premium offers single-side and paired knuckle-and-hub assemblies for selected vehicles. Choose the correct axle and side, then match the suspension, hub and brake connections.
Choosing A Loaded Steering Knuckle
A loaded assembly can include a hub bearing and dust shield, but the exact parts supplied vary. Check the wheel studs, axle nut and ABS sensor separately in the product contents.
Drivetrain, suspension equipment and brake type can affect the correct knuckle. Compare the listed mounting points and hub or axle connection with the vehicle's original configuration.
Frequently Asked Questions (FAQ)
Is the wheel hub the same part as the steering knuckle?
The knuckle provides mounting points for the wheel-end and suspension; the hub and bearing support the rotating wheel. A loaded assembly may combine these parts, while a separate knuckle may require them individually.
Does a loaded knuckle always include an ABS sensor?
The package varies. One listed Honda Accord knuckle-and-hub assembly specifies that the ABS sensor and axle nut are not included, so those items should not be assumed from the word loaded.
Are driver-side and passenger-side knuckles interchangeable?
Their steering, brake and suspension mounting features can be side-specific. Select the stated side or a pair that lists both positions for the vehicle.
Why can rear brake type affect a knuckle assembly?
The mounting arrangement must suit the brake system. One Subaru Forester rear assembly is listed for rear drum brakes and excludes rear disc brakes; that condition applies to that product.
Can suspension or steering work affect alignment?
Removing or replacing steering components can alter the wheel's alignment. After relevant work, follow the vehicle's alignment procedure; MOOG notes that outer tie-rod replacement can change toe settings.
