Timken NP372019 Differential Race - Rear

Timken NP372019 Differential Race

The Timken NP372019 differential race is a tapered roller bearing cup for rear differential pinion applications. It is built for vehicles that need reliable support under combined radial and axial loads, including Ford F-150, Ford Expedition, and Lincoln Navigator rear axle service.

Key Features

• Timken tapered roller bearing component for differential pinion support
• Outside diameter: 3.780 in. / 96.00 mm
• Width: 0.728 in. / 18.50 mm
• Bearing cup radius: 0.059 in. / 1.50 mm
• Engineered for load handling in compact driveline packaging
• Cross-reference: Schaeffler NP372019

Detailed Description

Timken NP372019 is a differential race used in rear axle assemblies with a 9.75-inch ring gear. As the outer cup for a tapered roller bearing, it works with the matching cone to support the pinion shaft and maintain proper bearing geometry under driving load. Timken’s tapered roller bearing design is known for handling both radial and axial forces, which is important in Ford truck and SUV rear differentials where pinion stability affects gear mesh and driveline smoothness. This part number is commonly selected for Ford F-150, Ford Expedition, Ford E-150, and Lincoln Navigator rear differential service.

What It Helps Address

• Rear differential pinion bearing wear
• Noise from a worn or pitted bearing race
• Excessive pinion play or looseness
• Rough gear operation caused by damaged bearing surfaces
• Service needs on 9.75-inch ring gear rear axles

Installation Notes and Tips

Replace the cone and cup together to maintain bearing match and reliability. Confirm the axle uses a 9.75-inch ring gear and verify the bearing dimensions before installation. Proper setup of pinion preload and gear contact pattern is critical after differential service. Fits 2003-2006 Ford E-150, rear. Fits 1997-2006 Ford Expedition, rear. Fits 1997-2006 Ford F-150, rear.
