Power Train Components Differential Pinion Bearing

Power Train Components differential pinion bearings are replacement axle differential bearings that support the pinion gear shaft inside the differential housing. The pinion bearing, also called a differential pinion bearing or pinion shaft bearing, carries the pinion gear that the driveshaft turns. That gear drives the ring gear. The bearing helps the pinion rotate smoothly and keeps friction, looseness and wear low.

Key Features:

• Supports the pinion gear and helps the differential let connected wheels turn at different speeds
• Built to handle the combined radial and thrust loads that the pinion places on the bearing
• Designed to meet OE specifications for fit, form and function
• Special coating for corrosion resistance
• Made to the brand's strict specifications by Power Train Components, Inc. (PTC), which works with OE manufacturers

Replacing a worn pinion bearing helps restore quiet, efficient driveline operation. A worn bearing often causes a whine or howl during acceleration or deceleration. Pinion bearings need correct preload and setup during installation. Select the specific part number for your application from the options in this product line.
