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.
