Product Details

Mevotech Supreme hub bearing assemblies are engineered in-house with application-specific upgrades for durability and performance in high-use passenger vehicles, SUVs, fleets, and working trucks. The MB70309 follows that approach with a service-focused design that supports faster replacement work and consistent fitment on covered Audi and Volkswagen applications. This part cross-references PBR70309 for the same application.

Compatible With select 2016-2024 Audi and Volkswagen models, including Audi A3, A3 Quattro, Q3, RS3, S3, TT Quattro, TTS Quattro, and Volkswagen Arteon, GTI, Golf R, and Jetta, depending on position and brake configuration. The MB70309 is a practical choice when replacing a worn hub bearing assembly on front or rear service points listed in the fitment data.

Common Reasons for Replacement

• Wheel bearing noise or growling from the hub area
• Excessive wheel play or looseness
• Uneven brake feel related to hub wear
• ABS-related service where the sensor is not part of the assembly
• Hub corrosion or bearing roughness during rotation

Installation Notes

Verify position, brake configuration, and model-year fitment before installation. This assembly is pre-greased and does not include an anti-lock brake sensor. Confirm flange bolt hole count, stud count, and dimensions against the original part before service. The Labor Saver design language from Mevotech indicates a focus on easier installation, but vehicle-specific procedures and torque specifications should always be followed.
