This tech tip from The Timken Company is designed to help you install and maintain Timken bearings, seals and components to maximize the life and performance of those bearings and the systems in which they operate.
If you are replacing a wheel bearing on a late-model vehicle, you will be dealing with a wheel speed sensor. In the past decade, wheel speed sensors have been moving from differentials, axles and knuckles to inside or on the wheel bearing or hub unit. At this location, the sensors are more accurate and often more protected from the elements.
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.
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.
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.
If a 2009-’10 Honda Pilot owner complains that the vehicle is making one or more clicking noises from the front suspension while accelerating or braking, it could be due to a faulty front suspension rear lower arm bushing bracket. If this is the case, replace both front suspension rear lower arm bushing brackets, and check the wheel alignment.
In the good old days, most serviceable wheel bearings were maintained at least every 25,000 to 30,000 miles during a brake job. During this process, races, stub-axles and cages could be inspected for damage and replaced if necessary. Today, the average life of a sealed wheel bearing or hub assembly is about 85,000 to 100,000 miles. But they can fail sooner than expected without a whisper.
For this article, we’ll be looking at a 2006 Mazda3i. We won’t spend much time on performing routine maintenance services, as we should all be familiar with the nuts and bolts of the job. The most important thing to ask yourself is, why are you doing this service? Sure it’s important to get fresh fluids and
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
In this technical bulletin, SKF provides updated technical information for preventing ABS sensor failure in pigtail-style hub assemblies. ABS system failures that happen shortly after hub unit installation can cause concern and customer dissatisfaction. Several items should be checked during the replacement process to prevent additional unnecessary repairs.
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.
Signs of a worn wheel hub bearing vary in severity. Some may be difficult to detect, leading to damage before corrective action can be taken. The timeframe in which damage occurs is linked to driving conditions and/or the mechanical practices that were followed at installation. Noise is a classic sign of a bad wheel bearing
