Automatic Transmission Differential Carrier Hyundai (45822-3B250)

Product Name

45822-3B250 Automatic Transmission Differential Carrier / Cup-Differential Case for Hyundai & Kia 4WD 6-Speed Transmission – 10-Hole, 47-Spline Precision Replacement

Product Overview

The 45822-3B250 Automatic Transmission Differential Carrier is officially referenced in Hyundai/Kia parts catalogs as a “Cup-Differential Case.” It is an internal transmission component used to support and locate the differential gear set inside compatible automatic transaxles. The part is associated mainly with 4WD/AWD 6-speed automatic transmission applications, and specialist transmission catalogs cross-reference it to A6MF1/A6LF-series applications. Hyundai/Kia EPC data also identifies 45822-3B250 as a direct differential-case component rather than an external transfer-case part.

For independent workshops, transmission rebuilders, wholesalers, and Hyundai/Kia spare-parts distributors, 45822-3B250 is suitable for replacing a worn, cracked, distorted, or spline-damaged differential housing. Its correct geometry is especially important because the carrier must keep the differential gears, bearings, and related drivetrain components correctly aligned while transmitting torque under acceleration, deceleration, and cornering loads.

Product Introduction

The Hyundai 45822-3B250 Differential Carrier / Differential Case Cup forms the structural body around the internal differential gear set. When the vehicle turns, the left and right drive wheels need to rotate at different speeds; the differential mechanism makes this possible while continuing to transfer engine torque to the drive wheels. The carrier provides the rigid and accurately machined structure required for this process.

Technical references for 45822-3B250 list 10 mounting holes, 47 internal splines, approximately 133 mm overall height, 62.90 mm and 65.05 mm neck diameters, a 16.85 mm pinion/satellite shaft hole, and approximately 162.10 mm mounting-flange outer diameter. These dimensions make part-number verification especially important because visually similar Hyundai/Kia differential cases can have different drive layouts or internal dimensions.

Product Specifications

Function and ApplicationThe dimensions and 3.15–3.30 kg reference weight are supported by specialist transmission/parts listings. One separate Kia catalog database lists 19.10 lb for the same number, so actual net and packed weight should be confirmed with Kingmay before calculating international freight. 

The primary purpose of the 45822-3B250 Differential Carrier is to provide a rigid and accurately located housing for the differential mechanism inside the automatic transmission.

Its key functions include:

• Supporting the differential gears: Keeps the internal gears and related components correctly positioned.

• Maintaining drivetrain alignment: Correct carrier geometry helps maintain proper bearing and gear alignment.

• Transmitting drivetrain loads: Handles mechanical loads generated while torque is transferred through the transmission to the drive wheels.

• Allowing different wheel speeds: Supports the differential mechanism that allows the inner and outer drive wheels to rotate at different speeds when the vehicle turns.

• Supporting smooth 4WD/AWD operation: Proper carrier condition contributes to stable torque transmission with reduced vibration and abnormal drivetrain noise.

• Protecting internal components: A structurally sound differential case reduces the risk of secondary damage to gears, splines, bearings, and shafts.

PartSouq's technical description likewise identifies the differential case cup as the structural part supporting the differential gears and helping distribute torque while allowing different wheel speeds during turns. 

Common Problems and Solutions

For transmission rebuilding, Kingmay recommends matching the OE number with the VIN, chassis information, old-part photo, and transmission specification before shipment. Kingmay's website states that its parts-matching team supports VIN, chassis-number, photo, and OEM-number verification. 

Installation and Fitment Notice

Installation should be carried out by a professional automatic-transmission technician. Before assembly, compare the replacement part with the removed unit and verify:

• OE number 45822-3B250

• 10 mounting holes

• 47 internal splines

• Neck diameters

• Bearing-seat condition

• Pinion/satellite shaft bore

• 4WD/AWD transmission configuration

• Differential gears and bearings for abnormal wear

Replacing only the carrier while retaining severely damaged bearings, gears, or contaminated transmission fluid may result in premature failure.
