Give the rear differential's inner pinion bearing a fresh running surface with the Schaeffler Differential Pinion Race NP434567, the tapered roller bearing cup cataloged for the rear inner position. It is a direct-fit replacement for many vehicles, among them the 1997-2006 Ford F-150, 1999-2006 Ford F-250 and 1997-2006 Ford Expedition.
Schaeffler tapered roller bearings pair strong load-carrying capacity with a compact design. They are used in wheel bearings, transmissions, differentials, transfer cases and other applications, and Schaeffler makes more than 100 million of them each year. In a pinion bearing, the tapered rollers of the mating cone ride against this cup to support the pinion gear.
- Load efficiency: Well suited to applications that see complex loading conditions.
- Load distribution: A broad contact area helps spread stress more effectively.
- Durability: Engineered with high-grade materials for reliability and service life.
- OE expertise: Designed and built to stringent OEM quality standards.
Signs a pinion bearing may need replacing: a whine or howl from the rear axle that changes between acceleration and coasting, a rumbling noise, or play at the pinion. Diagnose the cause before replacing parts. Inspect the matching cone at the same time, and follow the vehicle service information for pinion depth and preload.

Frequently Asked Questions
What does the Schaeffler NP434567 pinion race do?
It is the cup, or outer race, of the rear inner pinion bearing. The tapered rollers of the matching cone ride on it to support the pinion gear in the differential.
Which vehicles does it fit?
It fits many vehicles, among them the 1997-2006 Ford F-150, 1999-2006 Ford F-250 and 1997-2006 Ford Expedition. See the "Vehicles it fits" section for the full list and engine details.
Does this include the bearing cone?
No. This listing is the cup only, and the mating tapered roller cone is a separate part. Replacing the cup and cone together is common practice.
What are signs the pinion bearing may need replacing?
Signs include a whine or howl that changes between acceleration and coasting, rumbling, or pinion play. Worn gears can make similar noise, so diagnose the cause before replacing parts.
Is installing a pinion race a DIY job?
It usually means pressing the cup into the housing and then setting pinion depth and preload. Follow the vehicle service information, or have a qualified shop do the job.
