SKF BR930343 Wheel Bearing and Hub Assembly - Front

SKF BR930343 Front Wheel Hub Assembly

SKF BR930343 is a front wheel bearing and hub assembly for select Ford Ranger and Mazda B-Series applications. Built with SKF X-Tracker technology, it uses a double-row angular contact ball bearing design to improve hub stiffness and bearing capacity for stable handling and braking performance.

Use this SKF hub assembly when you need a direct-fit front hub solution for 2000-2002 Ford Ranger, front; 2001-2002 Mazda B3000, front; and 2001-2002 Mazda B4000, front. The BR930343 is engineered for vehicles that require a precise wheel pilot, brake pilot, and hub pilot interface.

Key Features

• SKF X-Tracker high-performance wheel bearing and hub assembly
• Double-row angular contact ball bearing arrangement
• Improved hub stiffness compared with a tapered bearing hub design
• Front axle application for Ford Ranger and Mazda B3000/B4000
• Triangular flange shape for application-specific fitment
• Designed and manufactured to SKF quality standards
• Part number: BR930343

Detailed Description

SKF BR930343 is engineered for front-wheel service on the Ford Ranger and Mazda B3000 and B4000 platforms listed below. The X-Tracker design increases bearing capacity and supports more consistent steering response and braking under demanding driving conditions. Key dimensions include a 1.111 inside diameter, 2.770 wheel pilot diameter, 2.840 brake pilot diameter, 3.940 hub pilot diameter, 5.885 flange diameter, and 2.217 flange offset. The triangular flange shape is part of the assembly’s application-specific design. This part cross-references YL521104AA for the same application.

Vehicle Fitment

• Fits 2000-2002 Ford Ranger, front, X-Tracker; w/o Pulse Vacuum Hub Locks
• Fits 2001-2002 Mazda B3000, front, X-Tracker
• Fits 2001-2002 Mazda B4000, front, X-Tracker
• Fits 2000 Mazda B4000, front, X-Tracker; FROM 6/22/00

Common Uses

• Restores front wheel hub support when bearing wear causes looseness
• Addresses wheel-end noise from a worn hub assembly
• Helps correct vibration or roughness at the front axle
• Supports braking consistency when hub stiffness has degraded
• Replaces a damaged or out-of-spec front hub on Ranger and Mazda B-Series trucks

Installation Notes and Tips

Confirm the vehicle’s year, model, and front-axle configuration before ordering. This application excludes 2000-2002 Ford Ranger models with Pulse Vacuum Hub Locks. Verify pilot diameters, flange offset, and flange shape against the original part to ensure proper fitment. Always inspect related wheel-end components during installation and follow the vehicle manufacturer’s service procedures.
