Fit Guaranteed

  • These hub & bearing sets will install just as your originals do. You can use your existing hardware.
  • Save time and money with direct fit hub bearing assemblies. No trips to the auto parts store or extra time trying to match up and press bearings.
  • Hub installation is a degree more difficult than changing a tire on most vehicles.


  • Some shops and dealers charge more for parts and repairs when they think the customer doesn't know what is involved. Now you can get the value you deserve. Knowing what this repair entails can be the difference between the value of doing it yourself, or the pain of a costly part or repair bill.
