49575-1U000 Center Support Bearing Fitment and Replacement Guide

The 49575-1U000 is identified as a center support bearing reference for certain Hyundai and Kia driveline applications, but the part number alone is not enough to confirm fitment for every vehicle. Before ordering, match the vehicle’s model year, drivetrain and VIN against a reliable parts catalog or the original-equipment reference, then compare the replacement with the removed assembly. This guide explains what to check, how replacement is generally approached, and what information to provide when requesting a quote. If you are sourcing for a Kia Sorento or another Hyundai/Kia vehicle, treat any catalog association as a starting point—not a fitment guarantee.

Who This Guide Is For

This guide is for parts distributors, repair businesses, fleet maintenance teams and procurement professionals evaluating a 49575-1U000 center support bearing. It is also useful for vehicle owners who want to collect the right information before speaking with a technician or supplier. The key objective is to reduce ordering errors by checking both vehicle application and physical component details. Installation should be handled by a qualified technician with suitable lifting and driveline service equipment.

What a Center Support Bearing Does

Basic design and function

A center support bearing supports an intermediate section of a multi-piece propeller shaft. Its bearing allows the shaft to rotate, while the surrounding support and rubber isolator help locate the assembly and manage vibration. The component works as part of the driveline, so condition and fit can affect noise, vibration and shaft movement. It does not correct unrelated issues such as damaged universal joints, worn mounts or a bent shaft.

Common construction and material considerations

A typical assembly may include a rolling bearing, an elastomeric support and a metal bracket, although details vary by vehicle and replacement design. Buyers should confirm whether the offered part is a complete support assembly or a bearing intended for a rebuild, since the service method and included components may differ. Material names alone do not establish suitability; dimensions, construction and vehicle-specific fitment must also match. Request a drawing or clear product photographs if the supplied configuration is unclear.

Confirming 49575-1U000 Fitment

Start with vehicle identification

Check the full 17-character VIN, model year, exact model and engine or drivetrain configuration before placing an order. A model name such as Sorento can cover multiple generations and driveline arrangements, so a broad model match may not identify the correct center support bearing. Confirm the OE part number through a vehicle-specific catalog, dealer parts lookup or other dependable parts reference. If the catalog lists superseded numbers, ask the supplier to verify the replacement chain rather than assuming that similar-looking numbers are interchangeable.

Compare the removed part and assembly

When the original component is available, compare its overall form with the proposed replacement and check that mounting points and bearing orientation agree. Useful measurements include the bearing inner diameter in millimeters (mm), propeller-shaft diameter in mm, and bracket mounting-hole spacing in mm. These measurements support identification, but they do not replace an OE-number or application check. Small differences in bracket shape, bearing width or offset can prevent correct installation even when the part appears similar.

Replacement and Inspection Guide

Before removing the bearing

First, confirm the replacement application and inspect the surrounding driveline for related damage. Symptoms such as vibration or noise can have more than one cause, so inspect universal joints, shaft condition, mounting points and other nearby components as appropriate. Photographing the installed orientation and marking relevant shaft relationships can help the technician preserve assembly references during service. Always follow the vehicle manufacturer’s service procedure and safety instructions for the specific vehicle.

General replacement sequence

1. Secure the vehicle using appropriate lifting equipment and follow the manufacturer’s safety procedure.
2. Record the installed component’s orientation and shaft relationships before disassembly.
3. Remove the propeller-shaft assembly according to the vehicle-specific service instructions.
4. Inspect the shaft, joints, brackets and mounting points for wear, damage or contamination.
5. Replace or rebuild the support using the method specified for the vehicle and the part supplied.
6. Reinstall the assembly, tighten fasteners to the vehicle manufacturer’s specification, and check operation after service.

This sequence is general guidance, not a substitute for a workshop manual. Some repairs require specialized tools or procedures, and incorrect shaft handling or assembly can create driveline vibration or a safety risk. Do not guess fastener torque, bearing orientation or shaft alignment values; obtain the applicable specification for the vehicle. If damage extends beyond the support bearing, address the full driveline condition rather than replacing one component in isolation.

Buyer Selection Framework

Match application, construction and supply scope

For a reliable purchase, begin with the OE reference and VIN-based application, then confirm the supplied product’s construction and dimensions. Ask whether the quotation covers a complete center support assembly or only a bearing, and clarify whether mounting hardware is included. For wholesale purchasing, also confirm packaging, quantity per carton, labeling and the supplier’s process for handling a fitment query. These details help align the ordered product with the repair plan and your inventory requirements.

Pricing, MOQ and lead time

Price and lead time can depend on order quantity, product configuration, packaging requirements, stock status and destination. Minimum order quantity (MOQ) and dispatch timing should therefore be confirmed in a written quotation for the specific part and shipment. Avoid comparing unit prices without checking what is included and whether the quoted reference matches the required application. For urgent repairs, confirm availability and estimated dispatch before arranging vehicle downtime or customer delivery commitments.

Supplier Evaluation Checklist

A supplier should be able to explain the basis for its fitment recommendation and identify what information it still needs to confirm the application. Ask for the product reference, available drawings or photographs, package contents and any applicable dimensional information. For repeat orders, clarify how revisions or superseded part references are communicated and how packaging is identified. Do not treat an unsupported compatibility statement or an unverified quality claim as a substitute for documentation relevant to your order.

• Can the supplier review the VIN, model year and drivetrain details?
• Is the offer for the complete support assembly or a bearing-only component?
• Can the supplier provide product identification and available dimensional details?
• Are MOQ, availability, lead time and packaging stated clearly?
• Is there a defined process for resolving a mismatch or fitment question?

How Shengfan Can Support Your Inquiry

At Shengfan, we can review a 49575-1U000 sourcing inquiry using the vehicle and product details you provide. To help us assess the request, share the VIN or confirmed vehicle application, OE reference, required quantity and any measurements or photographs of the original part. We can then clarify the product configuration available for quotation and discuss packaging, MOQ and lead time for your order. Final vehicle fitment should still be confirmed against the applicable parts information before installation.

Key Takeaways and Next Steps

The 49575-1U000 reference is a useful starting point for identifying a center support bearing, but it does not by itself prove compatibility with every Hyundai or Kia vehicle, including every Sorento variant. Confirm the VIN-based application, compare the OE reference and check the assembly’s key dimensions and supplied contents before purchase. For replacement, follow vehicle-specific service instructions and inspect the surrounding driveline rather than assuming the bearing is the only possible cause of vibration or noise. Send Shengfan your vehicle details, part reference, quantity and any available photos to request a fitment review and a B2B quotation.
