Active Wheel Speed Sensor Diagnostics

There are two “types” of sensors generally found on the modern car – the passive speed sensor and the active speed sensor. They both perform the same function, but work entirely different. The passive speed sensor uses a magnet with fine copper wire wrapped around it to create its own alternating magnetic field. The polarity changes from positive to negative as the tone ring passes by the magnetic field. This frequency changes with wheel speed.

Tech Tip: Frequently Asked Questions About Hub Assemblies

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.

Servicing Wheel Bearings And Wheel Speed Sensors

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.

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.

Memory Lane: Nuts, Bolts And Screws – Finishing A Chevy Restoration Project

Gary Goms discusses the mechanical challenges of restoring a truck that he began maintaining when he went to work in a gas station – back in 1957!

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.

2009-’10 Honda Pilot Clicking Noise Coming From the Front Suspension During Acceleration or Braking

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.

Bearing Diagnostics: Brinelling and Non-Noise Failures

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.

Mazda3i Vehicle Maintenance Checks

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

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

Tech Tip: Preventing ABS Sensor Failure in Pigtail-Style Hub Assemblies

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.
