My opinion? If your vehicle has more than 50,000 miles or has been driven in harsh conditions, then it’s logical to replacing wheel bearings on both axles. However, if your vehicle has low mileage and the other bearing is in good condition, replacing only the damaged bearing should not be a problem.

Wheel bearings allow cars and trucks to run smoother and more efficiently by reducing friction and supporting vehicle weight.

Includes built-in ball bearing support. Supports HEAVY loads & has a high torque capacity: 53 to 588 Nm. Bore (ID) sizes: 10 to 60 mm (0.393 to 2.362 in)

No built-in ball bearing support. Good for large orders & low to high torque needs: 1 to 2673 Nm. Bore (ID) sizes: 2 to 240 mm (0.078 to 9.448 in)

NOTE: Whether you DIY or your mechanic replaces the bearing, always install a new axle hub nut. Most hub nuts are prevailing torque fasteners. They’re used on critical components, like securing axle shafts to hub bearings, where a loose nut could lead to disastrous consequences.

I’ve replaced hundreds, if not thousands, of wheel bearings. One thing I’ve learned: A bad wheel bearing always gives an indication it’s failing. These include:

This heavy-duty clutch (aka a hold-back clutch) is good for high torque operations and ensures motion freezes in place. Bore (ID) sizes: 15 to 40 mm. (0.59 to 1.73 in)

Driving on a bad or failing wheel bearing is dangerous. If ignored, it can quickly turn into a safety issue and an expensive repair.

Under normal driving conditions, wheel bearings should last 85,000 to 100,000 miles. They can fail for several reasons, including:

Designed with grooves in the outer ring to offer more protection (than our L-type seal) against contamination and direct spray liquids. Liquid gets pushed out through outer grooves when in rotation.

The best protection for your bearing. Easy to install with a simple “drop-in” next to your bearing. No added space needed. CF seals offer 100% sealing efficiency against splashing liquids.

In my 50 years in the auto repair industry, I can’t recall one good story about wheel bearings. Most involve some sort of brake system failure, tires exploding, or fire from a seized red-hot bearing igniting axle grease. Bad wheel bearings should not be ignored.

Our GMN Gap Seals are plastic and a great choice for washdown applications, such as food conveyors and food manufacturing facilities

However, on some vehicles, it can be less than $100 per wheel. And you can save hundreds in labor if you DIY. If you don’t have the tools, most auto parts stores will lend you the specialty tools and equipment needed.

The cage and rollers are held together inside a hardened metal ring called a “race.” The seal keeps grease in and damaging water and debris out. Wheel bearings are installed inside, and secured to, the suspension, either by press-fit, bolts or a snap-ring. Once mounted, the wheel bearing rides on the axle shaft, allowing the tire/wheel to spin effortlessly.

No built-in ball bearing support. Has no RPM limits & Supports high torque needs: 609 to 14,060 Nm. Bore (ID) sizes: 38.09 to 220 mm (1.499 to 8.66 in)

The average cost to replace a sealed wheel hub bearing is around $350 per wheel. However, depending on the make and model, the shop labor rate ($47 to $215 per hour, according to AAA) and any additional damage could push the cost beyond $1,000 per wheel.

Includes built-in ball bearing support. Supports MEDIUM loads & low to medium torque capacity: 53 to 267 Nm. Bore (ID) sizes: 17 to 40 mm (0.669 to 1.57 in)

Older rear-wheel-drive cars or trailers use a set of two tapered roller bearings that face each other. These should be routinely serviced every 20,000 miles, or once a year.

On modern front- and four-wheel-drive cars, wheel bearings are a set of permanently sealed, precisely machined steel ball or straight roller bearings. The balls or rollers are encased in a “cage” that supports the bearings, allowing them to rotate freely.

We know that not every application requires super, high-precision bearings. We stock other industrial parts from quality brands.

Never reuse any wheel bearing (sealed or tapered) that’s loose, worn, noisy or shows any signs of wear. Trying to fix a loose or damaged wheel bearing can result in an accident and severe injury. Even if a pro suggests repairing a bearing, don’t let them.
