- Two material options: 65Mn version for OEM-level toughness and impact resistance; custom materials available upon request.
- Rigorous sealing performance testing – simulated torrential rain and dust storms ensure lubricating oil won’t leak or emulsify in harsh weather.
- Long service life – fewer replacements, less repair time, and reduced worry about breakdowns.

- Verify your vehicle is a compatible Lexus GS, Lexus IS, or Toyota Mark X model before ordering.
- This assembly fits both rear driver and passenger sides. Sold individually.
- Ensure the hub mounting surface on the axle beam is clean and free of corrosion before installation.
