Mercedes Sprinter 2500 Front Left Wheel Bearing & Hub Assembly – OEM | NCV3 Standard Suspension | #9063304220 (2007–2018)

DESCRIPTION:

A worn front wheel bearing on a Sprinter announces itself clearly — a growling, humming noise that changes with speed and gets worse in turns, sometimes accompanied by an ABS warning light. Left unaddressed, a failing bearing can progress to wheel wobble and complete hub failure. This OEM-spec front left wheel bearing and hub assembly for the NCV3 Sprinter 2500 is a direct replacement for the bearing unit inside the existing steering knuckle — no knuckle replacement required when the knuckle itself is still serviceable.

What This Part Does

The front wheel bearing hub assembly is the rotating interface between the stationary steering knuckle and the spinning wheel. It contains precision bearings that support the weight of the vehicle while allowing the wheel to spin freely with minimal friction. The integrated hub provides the mounting flange for the wheel and brake rotor, and on ABS-equipped models houses the tone ring for the wheel speed sensor.

Hub Assembly vs. Complete Knuckle Assembly — Key Difference

This listing is for the wheel bearing and hub unit only — not the complete steering knuckle assembly. If your knuckle is still structurally sound, replacing just the hub bearing is the more cost-effective repair. If the knuckle bore is worn or the knuckle is damaged, the complete assembly (part #9063304920 for left side) is the correct replacement.

Common Symptoms of a Failing Wheel Bearing

• Growling, humming, or roaring noise that changes with vehicle speed
• Noise that increases or decreases when changing lanes (load transfer)
• ABS warning light with wheel speed sensor fault codes
• Wheel wobble or looseness felt through the steering wheel
• Uneven or rapid front tire wear

Configuration Specific

This hub assembly is for standard suspension Sprinter 2500 models only — without heavy duty suspension and without the 4050KG or 3880KG weight variant. Always verify your suspension configuration and VIN before ordering.
