How to knowif wheel bearingis bad

Like all the components under the car, wheel hubs are continually exposed to water, dirt, dust, and other contaminants. They will corrode over time. Cars that live in cold climates are subject to salt and magnesium chloride. If you drive in the rain, some water may splash on the components in the undercarriage. But your wheel hubs get bathed in water. Wheel hubs are very exposed to the elements, so corrosion may cause problems sooner than it would for other components under the car.

MOOG’s commitment to continuous innovation means making existing designs even better. MOOG makes hub assemblies for a broad range of vehicles, so even older trucks can be fitted with our latest hub assembly innovations.

If you notice these symptoms during your test drive, it can’t hurt to physically inspect each wheel hub assembly on the vehicle. To do this:

Hub assemblies are critical for safe and reliable operation of a vehicle — and they're subject to some of the harshest punishments the road can dish out. High temperatures, extreme stresses, water and contaminants can take a toll on hub assemblies that aren't up to the challenge. That's why MOOG engineers continually introduce purpose-specific innovations that stand strong against harsh conditions — and make MOOG hub assemblies durable and reliable for years of hassle-free operation.

Whether you’re testing your own car or a customer’s car, you want to be able to detect the most common signs of a failing wheel hub assembly or a bad wheel bearing:

The wheel hub’s job is to connect the axle and wheel and to allow the wheel to spin smoothly. Most of the time a vehicle is traveling in a straight line, which puts only minimal stress on the wheel bearing. If your vehicle is out of alignment and pulling, you have to constantly turn slightly to keep the car going straight. Then the bearing is under the added stress of a slight turn all the time. This causes the bearing to wear faster.

Don’t forget to check the other components under the car! Worn ball joints and tie rod ends can cause symptoms like those caused by a bad wheel bearing.

No one likes comebacks, but they happen sometimes. You can reduce the number of comebacks your shop gets after a wheel hub assembly replacement with the three tips listed here.

4. Grime Defense Outboard Seal helps prevent contaminant buildup on the assembly exterior, working to shield bearings from friction-and corrosion-causing moisture and grime

In the early stages of bearing failure, you may hear the failure before you can feel it using techniques listed above. Another way to determine if the wheel bearing is failing is to measure the runout of the hub. Runout is a measurement of the amount of play in the wheel bearing. You need a dial gauge to precisely measure runout. The rule of thumb is that if the hub’s runout exceeds .004″, the bearing has failed.

If you’re looking for the key to reducing comebacks, it’s to use high-quality replacement parts. Installing a quality part means that there’s a low chance the customer will come back.

Good wheel hub assemblies are built like tanks. But sometimes they break or wear out, like any other part on a car. What causes wheel bearings to go bad though? There are three common causes of bearing failure: impacts, contamination, or improper alignment.

Sometimes when your tire hits a pothole, curb, or another large obstacle hard enough, your wheel bearing gets damaged. The bearing either breaks or becomes weaker, leading to eventual failure. Is your car driving differently after hitting a pothole or something else? Your wheel hub assembly may have taken a beating and need inspection.
