What is the Wheel Hub Assembly all about?
The wheel hub keeps a vehicle’s wheels in place. When properly functioning, the front hub ensures that a vehicle’s tires turn freely, that the ABS system works correctly, and that fuel efficiency is normal. A rear wheel hub gives a solid mounting point for the rear wheel to bolt onto and ensures smooth rotation at all speeds.
BEAR IN MIND
A bad or loose wheel hub assembly can lead to a catastrophic wheel failure. Because the wheel hub keeps the vehicle’s wheels in place, it is a critical part and should be fixed as soon as possible. Wheel hub replacements should be carried out in pairs, because when one is worn to the point of needing replacement, the other will generally have the same amount of wear.
HOW IT’S DONE
- The vehicle is planted on jack stands and wheel is removed
- The old wheel hub assembly removed
- The new wheel hub assembly is now installed
- The wheel is reinstalled and vehicle is removed from the jack stands
- The vehicle is road tested and checked for proper operation of front hubs and brakes
WHAT COMMON SYMPTOMS SHOW YOU MAY NEED TO REPLACE THE WHEEL HUB ASSEMBLY?
- Whirring or grinding noise from the area of the front hub, found near the center of the vehicle’s wheels, underneath the hubcap
- “Loose” steering, or steering that responds slowly
- Uneven brake application or excessive brake pedal travel before brakes are applied
HOW IMPORTANT IS THIS SERVICE?
The wheel hub assembly is an important component of any vehicle. If the wheel hub assembly is not in good operational condition, the wheel can separate from the axle. This is an extreme safety danger, and repair should never be delayed.
