What to know about the Wheel Bearings:
Wheel bearings allow wheels on a car to spin freely and stay secured to the car. Cars have four wheel bearings, one situated at each wheel. If the wheel bearings wear out, you will feel the wheels and steering wheel shake. Do not drive the car in this state and have it checked out as soon as conceivable by a professional mechanic.
Facts to Note:
There are two kinds of wheel bearing designs:
1) The bearings can be repaired by taking them apart, cleaning them, and re-packing them with fresh grease, or
2) The wheel bearing is of a “sealed” design that needs no service other than replacement when found to be faulty.
How to Fix:
Confirm faulty element.
Take away and change the wheel bearing.
Torque wheel bearing, fasteners and wheels to factory specifications.
Examine suspension and steering systems for any worn or brokenmechanisms.
Test drive vehicle.
On most cars manufactured before 1997, there are two wheel bearings per front tire (1 inner and 1 outer). Most car manufacturers recommend wheel bearing cleaning, re-packing with grease, and having them inspected every 30,000 miles. This is normally done with a brake service. Most cars manufactured after 1998 come with one wheel bearing in each tire, called a hub and bearing assembly. This is a sealed unit and cannot be serviced. When the wheel bearings go bad, they are simply removed and changed with new ones.
Common symptoms indicating you may need to change the Wheel Bearings:
Grinding, squealing, or abnormal noise from tires when you drive.
Steering wheel shakes when you drive the car.
If wheel bearing is locked up, the wheel will not easily move forward.
Importance of this service:
Wheel bearings permit the wheels to spin freely and at the desired speed. They’re also in control for keeping the wheels attached to the vehicle. As the bearings startto wear out or become broken, they impact the wheels ability to spin smoothly, freely, and securely. When this happens your vehicle will become shaky, and your wheels will not be secure.
