When Should The Wheel Bearing Flange Be Replaced?
The hub flange is ground zero for pulsation problems. Any runout in the flange will be magnified by the rotor. But, when do you replace a flange, stub axle or an entire hub unit? The answer can be confusing and will take some math and a micrometer.
Wheel Bearings: Pressing Bearings In Less Time With Fewer Comebacks
Servicing these bearings requires a little bit more finesse and tools when compared to hub units or tapered roller bearings. With the right tools and information, these jobs can be moneymakers.
Five Wheel Bearing R&Rs That Have a Bad Reputation
Some wheel bearing jobs can take as many as three hours and require removal of the knuckle from the vehicle. Collected in this article are some of the most difficult vehicles as reported by technicians, labor guides and bearing manufacturers.
Live-Axle Wheel Bearings
In 1963, almost every car manufactured in the U.S. had a solid rear axle. There were exceptions like the Corvette and Corvair. Today, many light- to medium-duty trucks still use live rear axles. While the design differentials have changed, the ends of the axles have not. The improvements in have been made in the materials
Wheel Bearings
Wheel bearings can be of either ball or tapered roller type. The ball bearings used for front wheel bearing applications are an angular type. An angular-type ball bearing will accept greater thrust loads than a Conrad-type bearing, which will accept a 100 percent load in the radial or thrust position and any combination of a 100 percent load. A tapered roller bearing will accept both a radial and a thrust load. All wheel bearings come in sets.
WHEEL BEARING Q&A: What, When & Why
How much load can a wheel bearing carry? On a typical passenger vehicle weighing around 3,400 pounds, each pair of front-wheel bearings, as well as the rear-wheel or axle bearings, support around 850 pounds, depending on the weight balance and driveline configuration. If it’s a 6,000-pound SUV, each bearing might carry about 1,500 pounds. This

Tech Feature: Servicing Worn Wheel Bearings
When a wheel bearing goes out on a vehicle, it may or may not give much warning. Typical clues include noise from the vicinity of the wheel, possibly some steering wander or looseness in the steering, and/or some abnormal tread wear on the front tires. Also, an ABS light could illuminate.
Tech Tip: Diagnosing a Noisy Wheel Bearing
The classic symptom of a bad wheel bearing is typically a cyclic chirping, squealing or growling noise that changes in proportion to vehicle speed. The sound may disappear at some speeds or only occur at certain speeds. The noise may get worse when turning, or it may disappear momentarily. So it’s difficult to make a diagnosis based on noise alone.
