45822-3B650 Transmission AWD Differential Cover For Hyundai Kia

Product Overview

The 45822-3B650 Transmission AWD Differential Cover / Differential Carrier is an internal component for selected Hyundai and Kia 6-speed automatic 4WD/AWD transaxles. Hyundai and Kia genuine-parts catalogs identify OE number 45822-3B650 / 458223B650 under the official description “CUP-DIFFERENTIAL CASE”, with part code 45822A. In the transmission aftermarket, the same component is also commonly described as a Differential Carrier, Differential Housing, Differential Case Cup, or AWD Differential Cover. 

Unlike an external cosmetic transmission cover, this component is part of the differential structure inside the automatic transaxle. It helps position the differential assembly, supports bearing and gear alignment, and maintains stable torque transfer to the drive shafts under acceleration, cruising, and cornering loads. Transmission specialists cross-reference 458223B650 mainly with A6MF1, A6MF2 and A6MF2H 4WD applications. 

Product Introduction

The Kingmay 45822-3B650 AWD Automatic Transmission Differential Carrier is designed for transmission overhaul and differential repair where the original housing has become worn, distorted, cracked, or damaged around the bearing, gear, or mounting areas. Correct differential carrier geometry is essential because even small alignment errors can affect bearing preload, gear engagement and power delivery.

For wholesalers, transmission rebuilders and Hyundai/Kia parts distributors, 45822-3B650 provides a convenient replacement option for selected Hyundai Tucson/ix35, Creta, Kona and Kia Sportage applications. Hyundai EPC data confirms that 458223B650 is used on certain 6-speed automatic 4WD configurations, while nearby numbers such as 45822-3B600 can correspond to 2WD versions, making OE-number and VIN verification important before ordering.

Product Features

• OE Reference 45822-3B650 – Matches the Hyundai/Kia CUP-DIFFERENTIAL CASE reference 45822A.

• Designed for AWD/4WD Applications – Used on selected 6-speed automatic four-wheel-drive transaxles. 

• A6MF-Series Compatibility – Common transmission references include A6MF1, A6MF2 and A6MF2H 4WD. 

• Precision Differential Support – Helps maintain stable differential gear and bearing positioning.

• Stable Torque Transfer – Supports smooth transmission of power from the final drive to the axle shafts.

• Direct Replacement Configuration – Hyundai catalogs classify it as a new direct-replacement component. 

• Suitable for Transmission Rebuilding – Ideal for automatic-transmission workshops, rebuilders, importers and wholesale parts distributors.

• OEM-Grade Supply Option – Kingmay states that its OEM-grade parts are sourced to match original-equipment fit, form and function requirements, with dimensional QC and traceability support. 

Product Parameters

For dimensions, HyundaiPartsDeal publishes 8.4 × 8.2 × 6.3 inches, which converts to approximately 213.4 × 208.3 × 160.0 mm, and a weight of 6.50 lb (about 2.95 kg). PartSouq independently lists the same OE number at 2.8 kg. Because these two reputable catalog references differ slightly, approximately 2.9 kg is the safest web-listing value until the exact Kingmay production batch is weighed before shipment. 

Important: KiaPartsNow currently shows a much higher database weight of 19.80 lb for the same number, which conflicts with HyundaiPartsDeal, PartSouq and several transmission-market listings. I therefore would not use 19.80 lb as the product net weight on the independent site.

Function and Application

The 45822-3B650 Differential Carrier performs several critical tasks inside the automatic transaxle.

Differential Assembly Support: It provides the rigid structural location required to keep differential gears and bearings correctly positioned.

Torque Distribution: During vehicle operation, torque passes through the final-drive and differential assembly toward the left and right drive shafts. The carrier helps keep those components aligned under changing load.

Wheel-Speed Compensation: During cornering, the inside and outside wheels travel different distances. The differential mechanism allows them to rotate at different speeds while still receiving drive torque.

Bearing and Gear Alignment: Proper differential carrier geometry helps maintain bearing position, gear contact and operating stability.

AWD/4WD Powertrain Support: Hyundai EPC references specifically identify 458223B650 on selected 6-speed automatic 4WD configurations. 

Transmission Repair: The component is commonly replaced during gearbox rebuilding when the original unit shows structural wear, bearing-seat damage, distortion, cracking or excessive internal clearance.

Common Problems and Solutions

PartSouq's description of this part also highlights its role in keeping the differential carrier aligned and notes symptoms such as whine, clunking, output play, oil leakage, metal contamination and vibration when the assembly is damaged or incorrectly supported. 

Installation Recommendations

Professional automatic-transmission installation is recommended. Before assembly, technicians should confirm the 45822-3B650 / 458223B650 OE number, transmission model, 4WD/AWD configuration, vehicle VIN and removed-part appearance.

The surrounding differential bearings, side gears, oil seals, pinion components and transmission fluid should also be inspected. Installing a new carrier while retaining damaged bearings or contaminated fluid can cause repeat noise or premature failure.

Quality Control

Kingmay states that its OEM-grade program emphasizes fit, form and function, with dimensional inspection, material certification availability, batch traceability and pre-shipment inspection. The company also offers OEM-number lookup and vehicle-fitment verification for B2B buyers.

For 45822-3B650, recommended inspection points include bearing-seat dimensions, mounting surfaces, differential interfaces, casting integrity, machined surfaces, dimensional accuracy, burr control and OE-number verification before packing.

Packaging and Private Label Service

Kingmay can support different packaging strategies for wholesalers and distributors:

• Neutral Packaging

• Kingmay Brand Packaging

• Customer Private Label

• Customized logo labels

• Customized cartons

• OEM-reference labels

• Export cartons and pallet packing

• Mixed-SKU container consolidation

Kingmay's public company page confirms export packing and labelling as well as private-label/OEM packaging on bulk orders, while its private-label program describes customized branding and packaging for long-term wholesale buyers. 

For differential components, reinforced internal packaging is recommended to protect machined surfaces and bearing areas from impact during international transportation.

MOQ and Wholesale Pricing

For this 45822-3B650 listing, the commercial MOQ can be set at:

MOQ: From 10 Pieces

The purchasing structure can be presented to buyers as:

• Buy More, Save More

• 10-piece trial/bulk starting quantity for this SKU

• Better unit pricing for larger orders

• Preferential pricing for repeat customers

• More competitive pricing for long-term annual purchasing plans

• Mixed-SKU orders supported

• Mixed cartons / LCL consolidation supported

• Full-container purchasing supported

Kingmay's website confirms a flexible B2B MOQ model, although its general corporate comparison currently states “from 50 pcs” for standard parts programs. A separate Kingmay sourcing guide shows 10 pieces per SKU for qualifying mixed orders, so the 10-piece MOQ should be treated as the specific commercial term for this 45822-3B650 listing and confirmed in the quotation, rather than a universal MOQ for every Kingmay product. 

Kingmay's private-label sourcing guidance also shows that committed-volume customers can negotiate lower pricing, supporting the commercial message that larger orders and long-term cooperation receive more competitive quotations. 

Logistics and Worldwide Shipping

Kingmay operates from Guangzhou, China, and shares export logistics through Nansha Port. Globalucar describes Nansha as its main South China export gateway, and Kingmay's ordering process states that parts are packed, documented and shipped through Nansha Port. 

For bulk 45822-3B650 orders, available logistics arrangements include:

• Sea freight

• LCL / groupage

• Full-container shipment

• Mixed-SKU consolidation

• FOB Guangzhou / Nansha

• CIF destination port

• Air cargo

• Express shipment for samples

Globalucar's current product process explicitly offers both FOB and CIF quotations. 

For Middle East customers, a practical sea-freight planning window is approximately 25–30 days, depending on destination port, vessel routing and transshipment. More specifically, current Globalucar route references show Nansha → Umm Qasr, Iraq at approximately 22–28 days, while Saudi routes vary by port and service, roughly 18–30 days. Therefore, “about 25–30 days” is suitable as a general planning estimate rather than a guaranteed transit time.

For Turkey, approximately 25–30 days can be used as a commercial planning estimate, but Kingmay's current public website does not publish a specific Turkey route time; the exact schedule should therefore be confirmed with the freight forwarder when quoting.

DHL / UPS Express Sample Shipping

For urgent trial orders and small samples, Kingmay can arrange express or air shipment rather than waiting for an LCL sea shipment.

Typical options include:

• DHL

• UPS

• FedEx where available

• Air cargo

Kingmay's main site confirms express air freight for smaller auto-parts orders, and its order process allows samples to be dispatched before bulk production. 

This option is particularly useful when distributors need a sample for dimension checking, transmission-fitment verification or quality testing before placing a larger 45822-3B650 order.

FOB / CIF Export Service

For international distributors, Kingmay can provide quotations based on different Incoterms.

FOB: Kingmay handles the goods, export documentation and delivery to the agreed Chinese export port, with Guangzhou/Nansha being its standard South China route.

CIF: Freight and marine insurance can be included to the agreed destination port according to the customer's requirement.

Kingmay/Globalucar also supports commercial invoices, packing lists, Bills of Lading, Certificates of Origin and export customs documentation. 

Other major Chinese ports can be discussed when a particular route or consolidated cargo plan requires them, but Nansha Port is the primary published Kingmay/Globalucar export gateway.

After-Sales Service

For this 45822-3B650 independent-site listing, the proposed commercial warranty is:

24-Month Warranty

After-sales coverage can include:

• 24-month manufacturing-defect warranty

• Fitment verification before shipment

• Pre-shipment product inspection

• Product photos or videos when requested

• Batch traceability

• Technical support

• Quality-claim assessment

• Replacement or negotiated solution for verified manufacturing defects

• Long-term distributor support

Kingmay publicly confirms pre-shipment inspection, dimensional checks, batch traceability and quality-support processes. 

Accuracy note: Kingmay's currently published product pages commonly show warranty periods such as 12 months on individual SKUs. Therefore, the 24-month warranty requested for 45822-3B650 should be treated as this product's specific commercial warranty and should also be written into the quotation/PI before publication, rather than described as Kingmay's universal warranty policy. 

Kingmay Advantage – China Factory-Integrated Supply

Kingmay describes its model as factory-integrated sourcing rather than simple reselling. It coordinates manufacturing resources, suppliers, quality control and export operations from Guangzhou, giving wholesale buyers access to production-side pricing and centralized purchasing.

The wider Globalucar platform also explicitly promotes direct factory pricing with no hidden intermediary markup. 

For buyers, this means fewer unnecessary sourcing layers, faster specification communication, centralized QC and more competitive B2B purchasing.

Kingmay Advantage – OEM-Grade Quality

Kingmay specializes in OEM-grade replacement auto parts for Japanese and Korean vehicles, with particular strength in Hyundai and Kia applications.

Its published quality program includes:

• OEM-equivalent fit, form and function targets

• Dimensional inspection

• Material certification availability

• SGS/TÜV supporting documentation on request

• Batch traceability

• Verified supplier network

• Pre-shipment inspection

• OEM-number cross-reference support

This is particularly valuable for an automatic-transmission differential carrier, where incorrect geometry can cause noise, bearing wear or drivetrain misalignment.

For 45822-3B650, Kingmay can offer a 10-piece starting MOQ as the SKU-specific commercial term, while buyers can combine different part numbers in larger consolidated purchases.

Kingmay's website confirms consolidated shipment capability, allowing engine, suspension, cooling, electrical and other parts to be combined into one Guangzhou shipment, reducing logistics cost per SKU. 

This is especially suitable for wholesalers that do not want to purchase hundreds of units of a single differential part at once.

Kingmay Advantage – Neutral, Kingmay or Private-Label Packaging

Customers can select packaging according to their market strategy:

Neutral Packaging – suitable for general aftermarket wholesale.

Kingmay Packaging – suitable for distributors selling under the Kingmay supply program.

Private Label Packaging – suitable for importers building their own local automotive-parts brand.

Kingmay's public company page specifically confirms private-label/OEM packaging availability for bulk orders. 

Kingmay Advantage – Consolidated Container Purchasing

Kingmay can combine multiple product categories into one shipment rather than forcing buyers to source every component from a separate supplier.

For example, a distributor can combine:

• Transmission parts

• Engine parts

• Water pumps

• Gasket kits

• Fuel injectors

• Suspension components

• Steering parts

• Electrical parts

into the same LCL or container program.

The Kingmay website specifically highlights its consolidated shipment capability from Guangzhou, with one set of shipping/customs documents and lower logistics cost per item.
