Timken 4244 Differential Pinion Seal - Front

Timken 4244 Differential Pinion Seal

Timken 4244 is a differential pinion seal built for front Dana/Spicer 28 axle applications. It helps retain gear oil at the pinion area while keeping dirt and road debris out of the axle assembly.

Key Features

• Precision sealing design helps control lubricant loss at the pinion seal location
• Reinforced outer case resists 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 build-up

What It Helps Address

• Gear oil seepage at the front differential pinion area
• Contamination entering the axle through a worn seal
• Heat-related seal wear from poor lubricant circulation
• Leakage caused by minor surface imperfections at the sealing diameter
• Seal damage during installation on Dana/Spicer 28 axle setups

Installation Notes

Inspect the pinion sealing surface before installation and clean the housing area thoroughly. Confirm the axle is a Dana/Spicer 28 front application for your Ford Ranger, Ford Explorer, Mazda B4000, or related vehicle before replacing the seal. Proper seating is important for sealing performance and long-term durability.

Quality Assurance

Timken oil and grease seals use reinforced construction and contamination-control features to support reliable sealing performance in driveline service.
