Timken 710429 Transfer Case Output Shaft Seal - Front Left or Rear

Timken 710429 Transfer Case Output Shaft Seal

Timken 710429 is a transfer case output shaft seal built for rear and front left applications on a wide range of Ford, Lincoln, Mazda, Mercury, and related vehicles. It is used where a precise seal is needed to retain lubricant and block road debris from entering the assembly.

Key Features

• Precision sealing design helps keep lubricant inside the transfer case and limits contaminant entry.
• Reinforced outer case helps reduce installation damage and adds durability.
• Ribbed rubber inner diameter seals minor spindle imperfections and supports positive seating.
• Internal contamination exclusion system helps block debris that can lead to leakage.
• Vent holes promote lubricant flow around the seal lip to reduce heat buildup.

Detailed Description

This Timken transfer case output shaft seal is engineered for direct-fit service on many Ford Explorer, Ford Taurus, Ford Edge, Ford Escape, Lincoln MKX, Lincoln MKZ, and Lincoln Continental applications, along with additional Ford, Mazda, and Mercury models. The seal’s construction focuses on maintaining a stable sealing surface, supporting lubricant retention, and reducing contamination at the shaft interface. Part number 710429 is also cross-referenced to National 710429 and Quality-Built 13757 for the same application.

What It Helps Fix

• Transfer case fluid seepage at the output shaft
• Contamination entering the seal area
• Heat-related seal wear from poor lubricant circulation
• Leakage caused by minor shaft surface imperfections
• Damage from worn or compromised sealing surfaces

Installation Notes and Tips

• Verify the position before ordering: this seal is listed for Rear and Front Left applications.
• Inspect the shaft surface for grooves, corrosion, or burrs before installation.
• Clean the sealing bore and shaft area thoroughly so the seal seats evenly.
• Use proper installation tools to avoid distorting the reinforced outer case.
• Confirm vehicle-specific fitment for your Ford Explorer, Ford Escape, or Lincoln MKZ before service.

Quality Assurance

Timken oil and grease seals use precision sealing geometry, contamination control features, and durability-focused construction for service in drivetrain sealing applications.
