Front INNER Wheel Bearing
Sold each
Restore smooth and reliable front wheel rotation with this
OE Match Front Inner Wheel Bearing. The wheel bearing allows the front hub and wheel to rotate
smoothly while supporting the weight and cornering loads placed on the
suspension. A worn bearing can cause noise, excessive play and poor wheel
control.

What Does the Front Inner Wheel Bearing Do?
The inner wheel bearing sits within the front hub assembly
and works with the outer bearing to support the rotating hub.
A correctly functioning wheel bearing helps:
- Allow
smooth wheel and hub rotation
- Support
vehicle and cornering loads
- Maintain
correct hub alignment
- Minimise
friction during wheel rotation
- Prevent
excessive movement at the wheel
- Support
consistent steering and handling
Why Do Wheel Bearings Fail?
Wheel bearings are subjected to continuous rotation, road
impacts, heat and heavy suspension loads. Wear gradually develops with mileage
and age.
Common causes include:
- Normal
bearing wear
- Incorrect
bearing adjustment
- Insufficient
or contaminated grease
- Water
and dirt contamination
- Damaged
bearing seals
- Corrosion
- Heavy
impacts from potholes or kerbs
- Incorrect
installation or overtightening
Poor lubrication or incorrect adjustment can considerably
shorten bearing life.
When Should the Front Wheel Bearing Be Replaced?
Replacement should be considered if:
- A
humming, rumbling or grinding noise is present
- Noise
increases with road speed
- Excessive
play is detected at the front wheel
- The
bearing feels rough when rotated
- Steering
or wheel stability becomes inconsistent
- The
bearing shows corrosion or surface damage
- Inspection
reveals worn rollers or bearing races
Wheel bearing noise can sometimes be confused with tyre or
suspension noise, so inspection is recommended before replacement.
Important Front Hub Checks
When replacing the inner wheel bearing, the complete front
hub assembly should be inspected.
Check the outer wheel bearing, bearing races, seals, spindle
and hub for wear or damage. Bearings should be correctly lubricated and
adjusted during installation.
If the mating bearing race is worn, scored or damaged, it
should also be replaced rather than fitting a new bearing against a damaged
surface.
Porsche 944, 928 & 968 Front Wheel Bearings
Front wheel bearings are essential components of the Porsche
944, 928 and 968 suspension and hub assemblies, allowing the wheels to rotate
smoothly while supporting substantial vehicle and cornering loads.
As these models age, bearing wear, deteriorated grease and
contamination can cause increased noise, roughness or excessive wheel movement.
When servicing Porsche front wheel bearings, the inner and
outer bearings, races, seals and hub should all be inspected to ensure the
complete assembly remains in good condition.
