What to know about the Wheel Hub Assembly:
The wheel hub keeps a vehicle’s wheels in place. When correctly functioning, the front hub ensures that a vehicle’s tires turn freely, that the ABS system works properly, and that fuel efficiency is normal. A rear wheel hub provides a solid mounting point for the rear wheel to bolt onto and ensures smooth rotation at all speeds.
Facts to Note:
A worn out or loose wheel hub assembly can lead to a disastrous wheel failure. Since the wheel hub holds the vehicle’s wheels in place, it is a critical part and should be fixed as soon as possible. Wheel hub replacements should be done in pairs, because when one is worn to the point of requiring replacement, the other will generally have the same amount of wear.
How to Fix:
The vehicle is supported on jack stands and wheel is detached
The old wheel hub assembly is removed
The new wheel hub assembly is 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
If you suspect that your wheel hub assembly needs to be changed, you should schedule service from one of your expert mechanics straightaway. Replacement of a wheel hub assembly may need specialized tools that are best left operated by professional mechanics.
Common symptoms indicating you may need to change the Wheel Hub Assembly:
Whirring or grinding noise from the area of the front hub, located 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 apply
Importanceof this service:
The wheel hub assembly is avital 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 hazard, and repair should never be delayed.
