No matter how sophisticated your car is, your wheels turn smoothly thanks to its humble wheel bearings - opens in new window or tab..

There are various suspension designs for different vehicles. At the end of the day, they all have a wheel spindle that supports the wheel hub - opens in new window or tab.. When you tighten your lug nuts to hold your wheel in place, you’re connecting the wheel to the wheel hub. The wheel hub rotates with the wheel. The spindle stays in place with the rest of your car. At that interaction point, you have wheel bearings - opens in new window or tab..

These tiny parts handle constant levels of friction and intense loads to keep the wheels spinning as intended. However, these bearings wear out. More importantly for a DIYer, there are common signs of wear you can learn to spot.

How Wheel Bearings Work

Four different types of wheel bearings on a white background. — A ring of internal rollers allow wheel bearings to rotate smoothly.

Wheel bearings are part of the car’s wheel assembly. The wheel mounts to the hub. The hub mounts to the spindle. The spindle mounts to the suspension, and the suspension mounts to your car. Wheel bearings allow the hub to spin smoothly on the spindle and support the vehicle’s weight. They are also responsible for handling the forces and friction created by driving and cornering.

This gives you an idea of what goes wrong when a wheel bearing goes bad. The wheel doesn’t spin freely. It wobbles under the weight of the car and while turning. Even a little bit of wobbling or clunking means a wheel bearing is bad.

In the case of total wheel bearing failure, everything would be grinding away 24/7. There’d be metal-on-metal contact. It’d be a mess.

Where are wheel bearings located?

Rear-wheel-drive (RWD) vehicles may have two front bearings and one rear bearing for each wheel. Usually, the front bearings are in a cone-shaped assembly containing roller bearings in a steel frame. (Ball bearings are round like a ball. Roller bearings are little metal cylinders that roll.) The rollers come in contact with the spindle shaft and the race. Sometimes, this style is included with front-wheel-drive (FWD) vehicles on the rear wheels.

The location of the wheel bearings speaks to the job that the wheel must do. In a RWD vehicle, for instance, the front wheels turn. They deal principally with the side-to-side forces of going left and right. The rear wheels don’t turn and only have to contend with the forward-backward forces of acceleration under power.

Vehicles with an independent rear suspension use sealed bearings mounted into the spindle or wheel hub. However, with a solid rear axle, the bearings are pressed onto the axle shaft housing and aren’t sealed. Instead, they get lubricated with rear axle gear oil.

How Long Wheel Bearings Should Last

There’s no hard, fast rule about wheel bearing lifespan. They could fail after 50,000 miles or go for 200,000 miles. It mostly depends on the make and model of the vehicle, plus the way you drive the car. If you drive on rough or uneven roads, you’ll probably go through more wheel bearings than the daily highway commuter. All of this to say, be mindful of the clunking and wobbling symptoms of a bad wheel bearing. Don’t think of the mileage alone.

Putting excessive loads on the bearings also can lead to undue stress. Finally, misalignment or worn suspension components can add more stress to the bearings, causing them to fail prematurely. Bear that in mind if you’re modifying your vehicle. If you’re throwing big spacers on your wheels, keep a close eye on those wheel bearings.

Can you drive with bad wheel bearings?

Even if you think there’s still time left in them, don’t do it. Once the bearing gets bad enough, the brakes can lock up, the rotors can break, or a hub - opens in new window or tab. can fail. Your wheels can come right off the vehicle. It’s a very dangerous situation.

Signs of Bad Wheel Bearings

Most often, you notice bad wheel bearings by their sound. At first, they create a gentle humming noise. It changes with the speed of the wheels. As wear becomes worse, the noise turns into a louder groan, howl, or growl. There could also be a clicking sound when accelerating or reversing, but this is often confused with the sound of bad CV joints.

Vibration is another common symptom. You may feel the vibration coming through the steering wheel as the bearings fail. It may be more noticeable at higher speeds. The vehicle can also start pulling to the side of the bad bearings, making it harder to control.

Depending on how bad the wear is, the ABS light may turn on. This happens because the bearing becomes so far out of specification that the wheel hub is no longer spinning square.

How do you check the condition of your wheel bearings?

Wheel play becomes evident as the bearings fail. You can perform a simple wobble test to check the bearings.

Park the vehicle on level ground and turn the engine off.
Raise each corner with a jack, one wheel at a time. Secure the vehicle on jack stands.
Holding the top and bottom of the wheel, press at the top while pulling on the bottom.

If the bearings are in good working order, the wheel should not move. If there’s wobbling from top to bottom, the wheel bearings may be failing. It could also be due to worn ball joints. Check if they are cracked and worn out. They’re the rubber joints behind the wheel—typically one top and one bottom—where the suspension mounts on the wheel side, not the car side. Additionally, you may notice uneven tire wear if the bearings are failing. A bad wheel bearing can cause the wheel to go out of alignment.

How hard is it to replace your wheel bearings?

To replace a sealed wheel bearing hub, you may need an hour or two and it’s not a job for beginners. You may need to disassemble components from the drivetrain or suspension.

Replacing separate bearings involves less disassembly. You need to remove the wheel, brake caliper, and brake rotor.

In either case, follow our complete how-to guide and video - opens in new window or tab. for step-by-step instructions.

What does it cost for a wheel bearing hub replacement?

It’s important to grease - opens in new window or tab. the cone-shaped front bearings on RWD vehicles regularly, but if they need to be replaced, they should only cost about $20. Sealed bearings can’t be greased. If they’re bad, you typically need to replace the drive hub, which can run about $120. If the steering knuckle needs to be replaced, the price could go up from there.

Consider Changing These Parts at the Same Time

If the wheel bearing is integrated into the hub assembly, the entire hub needs to be replaced. It’s also a good time to inspect or replace the CV joints and axles - opens in new window or tab. if there’s any wear. At the same time, you should inspect the suspension - opens in new window or tab. and replace anything that’s worn, as these parts can lead to more stress on the wheel bearings.

Because you will be working with the brakes at the same time, you can also check the brake pads and rotors - opens in new window or tab.. It’s easier to replace them now than later.

You also may need to have a wheel alignment performed after replacing the wheel bearings. If you did any work on the suspension, something may be out of whack.
