NSK 40BWD17D Wheel Bearing - Front

Front Wheel Bearing for Toyota and Scion

The NSK 40BWD17D front wheel bearing is built for select Toyota and Scion applications that require ABS-equipped hub support and consistent low-friction operation. It is a sealed, vehicle-specific bearing solution for front-end service on models such as the Toyota Prius C, Toyota Yaris, Scion iQ, and Scion xD.

Engineered with an integrated magnetic encoder seal, this bearing supports immediate ABS sensor response while helping maintain smooth wheel rotation in demanding daily driving conditions.

Key Features

• ABS equipped with a magnetic encoder for sensor signal support
• Premium OE technology for vehicle-specific fit, form, and performance
• Superfinished precision-matched raceway for reduced friction and long service life
• Advanced multi-lip seal design for water and contamination resistance
• Sealed-for-life construction with premium all-weather grease
• NSK 40BWD17D front wheel bearing for select Toyota and Scion front applications

Detailed Description

NSK develops rolling bearing products for automotive use with a focus on bearing life and operating performance. The 40BWD17D uses a sealed design and an integrated magnetic encoder to support ABS-equipped front wheel applications. Its 40 mm inside diameter, 75 mm outside diameter, and 39 mm outer race width make it a direct-fit service part for the listed vehicles.

Compatible With 2012-2019 Toyota Prius C, front; 2007-2019 Toyota Yaris, front; 2012-2015 Scion iQ, front; and 2008-2014 Scion xD, front. The NSK 40BWD17D is a practical replacement when the original front wheel bearing shows wear, noise, or ABS signal issues.

What It Helps Address

• Front wheel bearing noise or growling during driving
• Rough wheel rotation caused by bearing wear
• ABS warning light concerns related to encoder signal loss
• Water or contamination intrusion at the bearing seal
• Excessive friction from an aging sealed bearing assembly

Installation Notes and Tips

Verify the vehicle’s front application and ABS encoder style before installation. Match the bearing dimensions and orientation to the original part, and inspect the hub, knuckle, and surrounding components for wear or damage that could affect service life. For best results, follow the vehicle manufacturer’s service procedure and torque specifications.
