Because they’re absorbing so much energy on such a frequent basis, brake rotors wear out regularly and need to be replaced. However, driving on worn-out brake rotors can feel very similar to driving on a dead wheel hub. You may experience a wobbling feeling while braking—however, in the case of a dead hub or worn-out bearings, this may also be accompanied by a slight pull to the side with the damaged component. Take your vehicle to a mechanic to determine the exact cause of the problem and find out what part needs to be replaced.

Wheelhub bearing

The short answer is: Not for too long. Having bad wheel bearings can range from inconvenient and unpleasant to downright dangerous.

The major components of your wheel bearing and hub assembly are the bearings, hub, rotor, seal, and the drive shaft itself. Each of these parts must work in concert with the others to manage the forces that braking and cornering place on your vehicle during regular use.

The rotors on your vehicle help you brake while driving. Pressing the brakes in your vehicle causes the calipers to squeeze your brake pads against the rotors, creating friction that eventually causes the wheels to stop spinning and bring your car to a halt.

The hub is responsible for connecting the wheel to the axle of the vehicle. It also houses the wheel bearings. This metal casing typically comes in the shape of a disc with a slightly protruding midsection containing several studs. There’s also a hole in the middle for the bearing.

If water, grit, salt or sand get to the bearings, the grease in the hub assembly gets contaminated. This will wear down the bearings, and they will eventually give out.

Hubs can become stressed when the bearings they house fail. Since a worn out hub can make your vehicle extremely difficult to handle, you’ll want to replace your hubs as soon as possible whenever this happens.

Below, you’ll see a diagram showing the location of the wheel bearings and hub assemblies on a typical car. The hub, bearing, and rotor on each wheel is connected via a seal to the drive shaft (through the axle shaft). The construction of all wheel bearing and hub assemblies will look similar even when comparing large to small vehicles. For example, a Ford F-150 wheel bearing will be bigger, but look similar to a Ford Explorer wheel bearing.

Bearings generally come in the form of balls or tapers within a metal ring that rides on the shaft of the axle and fits into the hub. Due to the nature of the forces placed on wheel bearings, they are more prone to failure than many of the other components we’ll discuss here.

Drive shafts can become damaged in several ways, including when the wheel bearings or hub in your vehicle have begun to wear down. In this case, you’ll probably notice excessive vibrations when accelerating or braking, and might hear a knocking noise.

The seals that sit between your bearings and the drive shaft of your vehicle exist to keep out substances and materials that could cause the bearings to wear out faster—dirt, water, and other debris from the road being some of the most common.

Below, we’ve put together a diagram showing the different parts of wheel bearings and hubs, along with a description of each main component. Ready? Then let’s dive in.

Wheelbearing replacement cost

If you hear noises at the wheels, one explanation might be a need for a wheel bearing replacement at one or more wheels. The noises might be described as rattling, clicking, humming, growling, or squealing. It can be a real symphony of sound if you’re not careful.

For a national average across all vehicles, the average cost to replace the wheel bearings (for 1 wheel) is about $350 (including parts and labor). But KBB.com goes deeper than that. Based on analyzing 100s of actual repair orders, we put together the Kelley Blue Book Fair Repair Range to show you what you should expect to pay for this repair for your Toyota. Simply tell us the year, model and style of your Toyota and we’ll show you a fair price for the repair.

Recalls may not affect every vehicle of the same year, make and model. Use your VIN or plate to find out if your specific car has open recalls.

Wheel bearings and hub assemblies play a vital role in the performance of your vehicle, but they’re easy to overlook. After all, these parts are small and hard to see at a glance—so they don’t always get much thought. Still, you need to understand what they do and buy high-quality replacement parts when the wheel bearings in your vehicle wear out if you want to keep it running properly.

If you have bad wheel bearings, you might experience the vehicle pulling to one side, sloppy or loose steering, grinding and rattling noises, and uneven tire wear.

More than just noisy or bothersome, bad wheel bearings could also lead to real performance issues like inconsistent braking, spongy steering and handling, uneven tire wear and, in extreme cases, the wheels could fall off. No matter how much (or how little) you know about cars, you don’t want the wheels falling off, right?

Understanding where your wheel bearings, hubs, and related components are—and how they function—is vital for keeping your vehicle in proper working order. Use what you’ve learned above to keep a closer eye on these important parts and replace them with high-quality aftermarket components when required.

You’ll normally hear a rattling sound for some time before this occurs—so you’ll get plenty of warning. Still, it’s vital to replace a worn-out wheel bearing as soon as possible to prevent performance issues and more costly mechanical problems.

However, these seals also keep the grease used to lubricate your bearings inside the hub assembly. This grease is vital for prolonging the lifespan of your hub and bearings, so these seals need to be checked often and replaced if they have deteriorated.

In theory, wheel bearings could last as long as your Toyota. Unlike oil changes or tire rotations, there’s no standard maintenance schedule for replacing them. However, wheel bearings can be damaged if you hit a pothole, smack into a curb or bounce over a speed bump too fast.

The purpose of wheel bearings is to help the wheels of your vehicle turn with minimal friction when torque is sent to the wheels from the engine. When a wheel bearing begins to wear out, it becomes more difficult for the corresponding wheel to rotate, which can eventually cause handling problems and even permanent suspension damage.

The drive shaft of your vehicle is responsible for moving torque from the engine into the wheels, facilitating movement. The transmission sends kinetic energy from the engine through the shaft into the differential, rotating the axle shafts (which are connected to the wheel hubs on each side of the car).
