OEM Hyundai Right Passenger Outer Axle Shaft 49501-2W650

Product Overview

The Right Passenger Outer Axle Shaft 49501-2W650 is a front right CV axle assembly designed for Hyundai and Kia all-wheel-drive vehicles. As an important drivetrain component, it transfers engine torque from the transmission/differential to the passenger-side front wheel while allowing smooth operation during steering and suspension movement. The assembly is catalogued as Shaft Assembly-Drive, RH and is also known as an Axle Assembly or CV Axle Shaft Assembly.

This 49501-2W650 axle shaft is manufactured as a direct replacement solution for worn or damaged front right drive shafts. With precise spline matching, integrated CV joints, and balanced construction, it helps restore smooth power transmission, reduce vibration, and improve drivetrain reliability for vehicle repair and aftermarket replacement applications. 

Product Description

The 49501-2W650 Right Passenger Outer Axle Shaft Assembly is engineered for Hyundai Santa Fe Sport and selected AWD applications. Positioned on the front right passenger side, this CV axle assembly connects the transmission output to the wheel hub, allowing continuous power delivery while accommodating changes caused by steering angles and suspension travel.

Designed for professional repair shops, distributors, and aftermarket suppliers, this replacement axle assembly offers reliable fitment and stable operating performance. It is an ideal choice when the original axle has problems such as CV joint wear, damaged boots, clicking sounds during turning, or vibration during acceleration. Before installation, buyers should confirm OEM number, VIN, drivetrain configuration, and vehicle specifications.

Solution:
Check axle alignment, spline engagement, and surrounding drivetrain components. Confirm the replacement part matches OEM number 49501-2W650.

Problem 3: Grease Leakage Around Wheel Area

Possible Causes:

• Broken CV boot

• Loose boot clamp

• Aging rubber components

Solution:
Replace the damaged axle assembly or CV boot before dirt enters the joint and causes permanent damage.

Problem 4: Incorrect Fitment After Purchase

Possible Causes:

• Wrong left/right side selection

• Different drivetrain configuration

• Regional vehicle specification differences

Solution:
Verify VIN, original part number, vehicle year, engine type, and AWD/FWD configuration before ordering.
