NSK KH20003 Wheel Bearing Kit - Rear

OE-Style Rear Wheel Bearing Kit

The NSK PROKIT KH20003 is a rear wheel bearing kit built for select Volkswagen and Audi applications that use ABS with a magnetic encoder. It combines OE-focused fitment with low-friction bearing performance, sealed-for-life construction, and corrosion-resistant sealing for daily driving and demanding road conditions.

Compatible with rear applications on Volkswagen GTI, Golf, Jetta, e-Golf, Golf SportWagen, Beetle, Clasico, and Audi A3 models, this kit is engineered for precise hub support and consistent ABS signal output. The NSK PROKIT line focuses on vehicle-specific service parts that match original equipment requirements.

Key Features

• Premium OE technology with vehicle-specific fit, form, and performance
• Superfinished, precision-matched bearing raceway for low-friction operation
• Advanced multi-lip seal design for water and contamination resistance
• Sealed-for-life construction with premium all-weather grease
• Integrated magnetic encoder seal for immediate ABS sensor response
• ABS equipped design with magnetic encoder type
• Rear, non-driven application

Detailed Product Overview

NSK KH20003 is a rear wheel bearing kit designed around the demands of modern compact and midsize platforms that rely on integrated ABS wheel speed sensing. The magnetic encoder helps maintain accurate signal delivery to the ABS system, while the sealed bearing design supports smooth rotation and reduced maintenance needs. As part of the NSK PROKIT line, this service kit reflects the brand’s OE manufacturing background and focus on bearing life and operating performance.

This part number, KH20003, is a direct-fit service solution for rear wheel bearing replacement on select Volkswagen GTI and Audi A3 rear applications, along with related Volkswagen Golf and Jetta fitments. It is also listed for rear e-Golf and Golf SportWagen applications where the same hub and encoder configuration is used.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Wheel bearing noise such as humming or growling from the rear
• Excessive wheel play or looseness at the hub
• ABS warning lights caused by encoder signal issues
• Rough wheel rotation from worn or contaminated bearing surfaces
• Water intrusion and seal wear in high-exposure driving conditions

Installation Notes and Tips

• Verify rear fitment by year, model, and suspension configuration before installation.
• Confirm the ABS encoder style matches the vehicle’s original setup.
• Inspect the hub flange, brake pilot diameter, and wheel pilot dimensions during service.
• Replace worn mounting components and clean the knuckle and mating surfaces before assembly.
• Use proper torque procedures for the CVJ bolt and wheel fasteners during reassembly.
