“Unusual noises” is quite vague, but for a good reason. There are many, many unusual noises associated with a worn wheel hub bearing. Some of the most common noises include:

How to tell which wheel bearing isbadwhile driving

This happens when the wheel bearing becomes bad enough. Most likely, you will hear noises before uneven tire wear happens. A worn wheel bearing makes the wheel loose. This causes the tire to wear out unevenly.

The crackling noise is a result of a worn or damaged outer CV-joint. It may also mean excessive bearing endplay due to poor clamping.

Covering applications for European, Asian and American brands, NSK produces more generation 3 hub bearings than any other manufacturer.

A worn wheel hub bearing is a pretty big deal. If you let it go on long enough, the wheel could literally fall off while you’re driving. That could cause a catastrophic accident that puts your life and others’ lives at risk. That’s why it’s important to watch out for bad wheel hub symptoms.

If you hear a grinding noise, that means there’s a loss of integrity in the steering or suspension system. For instance, there may be roller or raceway damage. When you have a worn wheel hub bearing, this noise is prominent when the vehicle is turning.

Many of the bearings have integrated magnetic encoders in the inboard seals to provide information to vehicle braking and stability control systems and most designs use ball bearings to reduce frictional torque and support low fuel consumption. For heavier load applications, such as some SUV and Pick-up applications, tapered roller bearings are utilised.

When a wheel hub bearing wears out, it puts extra stress on the CV-joint. That can cause the knocking/clunking noise when you turn the vehicle.

This noise is particularly prominent when the vehicle is traveling in a straight line. It gets worse when the vehicle is turning slightly at a speed of 15-50 mph. In a normal situation, you can pinpoint the problematic wheel bearing if you hear this noise. In most cases, the bad bearing is the cause of the rumbling noise.

NSK has introduced cold forming techniques to achieve more efficient manufacture and lighter, more compact hub units. Integrated sensors provide vital information to the various vehicle dynamic systems, and some of the most advanced sealing and lubricating technologies have been used to ensure excellent durability and reliability. This generation is the most straightforward to install, given its “bolt-on” arrangement.

The second generation Hub unit bearings from NSK integrate a mounting flange to the bearing outer ring. This facilitates mounting the bearings to the vehicle or to wheel the depending on the type.

The first generation Hub unit bearings from NSK integrate the previously separate bearings into one unit along with seals and pre filled lubrication.

Wheel bearings are to be found on each axle and have to withstand a whole variety of loads from forward propulsion, turning and stopping. And they have to be sturdy enough to not only support the various driving loads, but arduous environmental conditions too.

Worn bearings become loose. As a result, excessive runout happens. This causes the brakes to pulsate or pull. In other cases, a corroded or pitted bearing transmits the vibration through the steering. This can cause pulling to one side, too. Your vehicle will pull to the side of the failed wheel bearing.

When your wheel is vibrating and/or wobbling, the bearing is very loose. It’s because the bearing has lost its clamp. There may be some severe mechanical damage, too.

When a wheel hub bearing goes bad, you may feel some looseness in the steering wheel. When a bearing wears down, it becomes loose within the wheel hub and spindle. This will make your steering wheel feel loose.

The clearance is pre-set, leading to a more reliable and straightforward mounting, and the pre-lubrication by NSK with the latest greases means that mechanics can take the bearing directly from the package to put into the vehicle, thereby avoiding accidental contamination or filling with the incorrect quantity or quality of lubricant.
