SKF 29471 Differential Pinion Seal - Rear

SKF 29471 Differential Pinion Seal

SKF 29471 is a differential pinion seal built for driveline sealing performance where the pinion shaft enters the axle housing. It is designed to retain gear lubricant and help keep road debris, water, and other contaminants out of the differential assembly. This seal is a direct-fit service part for applications that call for a 2.938 shaft diameter, 4.943 outside diameter, and 1.375 width.

Key Features

• Part number 29471 differential pinion seal for driveline and axle service
• Polyacrylate sealing surface type for demanding sealing conditions
• 2.938 shaft diameter for application-specific fitment
• 4.943 outside diameter and 1.375 width for proper housing engagement
• SKF sealing design backed by long-running seal engineering experience
• Cross-reference part numbers include 47681 and 107368 for the same application

Detailed Description

SKF 29471 is engineered as a differential pinion seal for axle and driveline repair work where maintaining lubricant retention is critical. SKF has a long history in seal development, and this part reflects that focus with premium materials and a design intended to match the application’s operating environment. For technicians servicing a differential pinion seal on a Ford F-150, Chevrolet Silverado, or Dodge Ram application, correct seal dimensions are essential for reliable sealing and proper axle service.

The polyacrylate sealing surface type supports consistent contact at the shaft interface, while the listed dimensions help confirm the seal before installation. Use SKF 29471 when the vehicle specification calls for this exact size and design. The part number 29471 is also useful when cross-checking service references during differential repair or axle reseal work.

Common Problems This Seal Helps Address

• Gear oil leakage at the differential pinion area
• Contamination entering the axle housing through a worn seal
• Wet or oily residue around the pinion yoke and seal surface
• Noise or wear concerns caused by low lubricant level after leakage
• Repeat seal failure from incorrect size or worn sealing surface

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width against the original seal before installation. Inspect the pinion yoke and sealing surface for grooves, corrosion, or damage that can affect seal life. Clean the housing bore thoroughly and install the seal squarely to avoid distortion. Confirm differential fluid level after service and check for leaks during road testing.

Quality Assurance

SKF designs and manufactures seals to high quality standards using application-specific materials and bonding methods. The brand’s seal engineering heritage dates back to the first integrated shaft seal in 1928, and SKF 29471 follows that long-standing focus on durability, lubricant retention, and contamination control.
