Magneti Marelli wheel-end product performance and quality begins by ensuring that bearings and hub assemblies meet O.E. specifications and incorporate only premium components. Complete O.E. specification hub assemblies include a pre-attached ABS tone ring, encoder seal or sensor, wire harness and connector. All individual bearings — and bearings incorporated into hub assemblies — are manufactured using only premium-grade steel and are matched for even loading of rolling elements. All raceways are highly finished for smooth, quiet, long-lasting performance.

FEATURES

  • Exclusive seal design eliminates contamination, prolonging bearing life and ABS performance
  • O.E. design eliminates the need for re-lubrication and Magneti Marelli hubs feature cooler-running non-metallic retainers
  • Integral raceways provide proper clearance between bearing and the raceway for smooth, quiet operation
  • All ABS equipped hubs and bearings include O.E. ABS sensors and/or plugs for O.E. fit and function

BENEFITS

  • Rigorously controlled manufacturing processes ensure exact matching of bearing raceways and rolling elements to consistently deliver superior performance and minimize noise and vibration
  • 100% post-assembly hub inspection ensures proper ABS signal and quiet operation
  • All Magneti Marelli hub assemblies and bearings start with premium steel and undergo computer-controlled heat treatment to deliver lasting performance
Installation Tips
  • Use an Axle Nut Socket to remove the axle nut
  • After removing the brake caliper, suspend it using a Caliper Hanger to avoid damage to the brake hose
  • A Wheel Hub Removal Tool can help remove a stubborn wheel hub assembly from the knuckle
  • During installation, use a Torque Wrench to tighten the axle nut to the manufacturer's specification. Do not use an impact wrench as it is easy to over tighten the axle nut. The torque specification can be found in your owner's manual
Symptoms Of A Failing Wheel Bearing & Hub

Wheel hub units are low maintenance parts, but that doesn’t mean they last forever. Uneven road surfaces, heavy driving conditions (such as towing or racing), and under-inflated tires put extra strain on the hub bearing and can lead to premature failure. Common signs of a bad hub unit include:
  • A humming, rumbling or growling noise that increases with acceleration
  • A loud constant whining or grinding noise when the vehicle is in motion
  • Excessive play in the steering wheel
  • Steering wheel vibration that changes with the vehicle speed or as the vehicle turns
  • ABS system malfunction

How To Identify The Faulty Wheel Bearing & Hub

It is often difficult to pinpoint which hub unit has gone bad while driving because noise and vibration travels through the frame of the vehicle. Here are a two tests you can do to help identify which hub unit has gone bad:

Shake Test: Identifying Play or Looseness
  1. Lift your vehicle so the wheel is off the ground
  2. Place your hands on the sides of the tire and try to shake the wheel
  3. Now place your hands on the top and bottom of the tire and try to shake the wheel again
  4. If you feel movement in both directions, you have play in your bearing and it needs to be replaced
  5. Note: If you feel movement when shaking the wheel left to right, but not top to bottom, you could have a worn out tie rod end. Similarly, if you have movement top to bottom, but not left to right, you may have a worn out ball joint.
Spin Test: Identifying Noise or Grinding
  1. Lift your vehicle so the wheel is off the ground and can spin freely
  2. Spin the wheel, in either direction, and listen for a grinding or howling noise
  3. If you hear a loud grinding or howling noise, that increases with the speed of the wheel, you have a failed bearing that needs to be replaced
  4. Note: It is best to test both front or both rear bearings at the same time so you can compare the difference between the two sides. If you have a failed bearing, there will be a noticeable difference in the amount of noise you hear during this test
