National 471847N Differential Pinion Seal - Rear or Rear Outer

National 471847N Differential Pinion Seal

National 471847N is a differential pinion seal built for rear outer applications that need a precise seal at the shaft and housing bore. With a 1.375 in. shaft diameter, 2.565 in. outside diameter, and 0.500 in. width, it is sized for specific Mitsubishi axle and differential setups found in Mitsubishi Eclipse, Galant, Outlander, and related Chrysler, Dodge, and Plymouth applications.

National has supplied sealing solutions for more than 75 years, and this seal reflects that focus with polyacrylate sealing material and Redicoat surface treatment for dependable sealing performance in driveline service. This part cross-references BBB Industries 13878 for the same application.

Key Features

• Part number 471847N differential pinion seal for rear outer driveline service
• Polyacrylate sealing material for consistent oil sealing performance
• Redicoat finish for improved sealing surface characteristics
• 1.375 in. shaft diameter and 2.565 in. outside diameter
• 0.500 in. width for the specified housing bore and axle fitment
• Compatible with Mitsubishi axle and Mitsubishi differential applications

Detailed Description

National 471847N is an oil seal engineered for the pinion area in rear differential assemblies. Its dimensions include a 34.930 mm shaft diameter, 65.150 mm outside diameter, and 12.700 mm width, with a 65.050 mm housing bore specification. These measurements matter for proper sealing at the differential pinion location, where gear oil retention and contamination control are critical.

Fitment includes 2004-2006 Mitsubishi Outlander, rear outer; 1992-1998 Mitsubishi Eclipse, rear outer; 1992-1995 Mitsubishi Expo, rear outer; 1993-1994 Dodge Colt, rear outer; 1971-1980 Dodge Colt, rear outer; 1992-1994 Mitsubishi Expo LRV, rear outer; 1992-1994 Plymouth Laser, rear outer; 1992 Mitsubishi Galant, rear outer; 1984-1991 Dodge Colt, rear outer; 1990-1991 Mitsubishi Eclipse, rear outer; 1990-1991 Mitsubishi Galant, rear outer; 1990-1991 Plymouth Laser, rear outer; 1987-1989 Chrysler Conquest, rear; 1983-1989 Mitsubishi Starion, rear; 1983-1987 Hyundai Pony, rear outer; 1985-1987 Hyundai Stellar, rear outer; 1984-1986 Dodge Conquest, rear; 1984-1986 Plymouth Conquest, rear; and 1978-1979 Dodge Challenger, rear outer.

What It Helps Fix

• Gear oil seepage at the differential pinion area
• Fluid loss from worn or hardened seal lips
• Contamination entering the rear differential housing
• Noise or driveline issues caused by low lubricant level
• Seal leakage on Mitsubishi axle and Mitsubishi differential setups

Installation Notes and Tips

Confirm shaft diameter, housing bore, and seal width before installation to match the differential housing exactly. Inspect the pinion surface for wear, scoring, or corrosion before fitting the new seal, and verify that the sealing surface is clean and dry. For vehicles such as Mitsubishi Eclipse, Mitsubishi Galant, and Dodge Colt applications, confirm rear outer or rear differential position and axle configuration before ordering.
