Detailed Description

Timken SP450701 is engineered as a replacement wheel bearing and hub assembly for front driveline service on Nissan Frontier, Nissan Xterra, Nissan Pathfinder, and Suzuki Equator applications. The assembly uses OE-developed testing to guide design, materials, and manufacturing processes, with attention to runout control, seal integrity, and bearing surface finish. Those details matter in front-end service because they affect wheel smoothness, braking consistency, and long-term durability.

This hub assembly features a 114.30 mm bolt circle diameter, 140.00 mm flange diameter, 93.00 mm hub pilot diameter, and 65.91 mm wheel pilot diameter. The driven configuration, 29 spline count, and integrated ABS sensor make it a practical replacement for vehicles that rely on accurate wheel-speed input and stable hub support. Search terms such as front wheel bearing and hub assembly for 2005-2018 Nissan Frontier, front hub assembly for 2005-2015 Nissan Xterra, and 2019-2023 Nissan Frontier front hub replacement all point to this part number, SP450701.

Common Problems This Part Can Address

• Front wheel bearing noise, humming, or growling
• Excessive wheel play or looseness at the hub
• ABS warning light caused by wheel-speed signal issues
• Vibration or roughness from worn hub bearing surfaces
• Uneven braking feel related to hub runout

Installation Notes and Tips

Confirm vehicle year, model, and front position before ordering. Verify spline count, bolt circle diameter, hub pilot diameter, and ABS sensor configuration against the original part. Clean the mounting surface thoroughly, inspect the axle and knuckle for wear, and torque fasteners to the vehicle manufacturer’s specification during installation of Timken SP450701.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes for hub bearing assemblies. Premium seals, precision bearing profiles, and 100% tested ABS sensors are part of the product’s quality control approach for consistent front-end performance.
