Product Description
The 90311-45036 genuine TOYOTA differential pinion oil seal (Type T oil seal) is a precision sealing component of the vehicle's drivetrain. Its primary function is to maintain a reliable radial seal between the differential drive pinion shaft and the housing, preventing gear oil leakage and blocking external contaminants, moisture, and dust from entering the differential housing.
Technical Specifications
- Manufacturer: TOYOTA OEM
- Part Number: 90311-45036
- Part Name: Differential Pinion Oil Seal (SEAL, TYPE T OIL)
- Fitting Position: Differential input shaft / drive pinion shaft
- Design: Type T radial shaft seal with a metal reinforcing casing, garter spring-loaded elastomeric primary sealing lip, and integrated dust lip
- Fluid Resistance: Resistant to synthetic and mineral-based gear oils, as well as high thermal loads
Operation and Symptoms of Failure
The input oil seal is subjected to continuous friction, high rotational speeds, and fluctuating operating temperatures. Over time, the elastomeric material may harden, degrade, or wear, leading to a loss of sealing capability.
- Oil Leakage: An oil film or active oil dripping appears at the junction of the drive pinion flange and the differential housing.
- Insufficient Lubrication: Lubricant loss due to leaks can lead to premature wear and overheating of the differential bearings and gears.
- Noisy Operation: Increased friction resulting from low oil levels can produce a characteristic humming or mechanical whine in the rear or front axle.
