Product Description:

Basic Description and Technical Characteristics
Applicable System: Mainly used for the rear axle differential assembly or the transmission reduction mechanism of the transfer case, to achieve differential rotation of the left and right wheels and power output
Core Function: Receives power from the transmission shaft, through the planetary gears (ring gears) and the angle gears (small gears), to reduce and increase torque and distribute it to the two half shafts on both sides
Gear Parameters: Usually adopts a helical bevel gear design, with smooth transmission and low noise, the main reduction ratio is commonly 4.3:1 or 4.875:1 (depending on the vehicle model)
Connection Structure: The input end is connected to the transmission shaft through a flange fork, and the output end is connected to the wheels through the half shaft, with a drain plug and oil injection hole on the housing
Material and Process: The housing is mostly cast iron or aluminum alloy die-cast, the gears are treated with alloy steel carburizing and quenching, featuring high hardness and fatigue resistance

Core Advantages and Selling Points
Original Equipment Specification High Compatibility
Manufactured strictly in accordance with Toyota OEM standards, can directly replace the original vehicle parts, without the need to adjust the tooth side clearance or replace the supporting components.
Efficient and Stable Power Transmission
The helical bevel gears have a large contact area for meshing, high transmission efficiency, effectively reducing power loss, improving fuel economy and driving smoothness.
High Durability and Adaptability to Frequent Use
The surface of the gears is hardened treatment + precise gear grinding process, resistant to wear and impact, suitable for frequent starting and stopping in cities and mild off-road conditions.
Excellent Sealing Performance and Oil Leakage Prevention
The joint surface is finely processed, combined with high-quality oil seals and gaskets, effectively preventing oil leakage, extending the maintenance cycle.
Controllable Maintenance Cost
There are a large number of high-quality substitutes available on the market, the price is approximately 60%-70% of the original factory parts in 4S stores, significantly reducing maintenance burden.

Main Application Scenarios
Differential Assembly Replacement: Used to replace the original differential that has failed due to gear wear, abnormal noise, oil leakage or slipping, to restore the vehicle's driving capability
Four-wheel Drive System Repair: In RAV4, HIACE and other four-wheel drive models, as a key repair component of the transfer case's rear axle reduction unit
Accident Vehicle Restoration: After rear axle damage caused by a collision, replacing this reducer can ensure the safety of the power system
Used Car Restoration and Value Enhancement: Replacement significantly improves the driving system condition, enhances buyer confidence and residual value assessment
Automotive Parts Batch Supply: Due to the large global ownership of Toyota models, this model is one of the mainstream transmission components in the international aftermarket market
