The standard bearing seal consists of nitrile/BUNA-N rubber bonded to a metal washer. The washer is made of SPCC cold rolled steel for chrome steel bearings or 304 stainless steel for stainless steel bearings. High temperature PTFE (Teflon) seals or Viton seals are available on some sizes. The inner lip of the seal rubs against the bearing inner ring to provide an effective seal against smaller particles such as dust and moisture while preventing lubricant leakage. Contact seals produce much higher frictional torque levels than shields and reduce the maximum speed of a bearing. Below -40°C nitrile rubber and viton will stiffen and provide a less effective seal so PTFE seals or metal shields should be considered for very low temperatures.

How much is it to fix or replace a wheel bearing? That depends on the make/model of your car as well as the type of bearing. RepairPal estimates a wheel bearing replacement will cost you between $300 and $400. This estimate can be accurate for most vehicles. However, if we look at the pricing for the popular Toyota Tacoma, the price jumps as high as $740. Using a whole knuckle assembly from NAPA or other parts suppliers will cost between $250 and $500, plus labor. Like most repairs, if you do them yourself, you can save some money. However, when it comes to serviceable bearings and press-in bearings, we recommend you let the pros handle the repair, especially if you live in the rust belt.

Tapered roller bearings are serviceable, which means they can be removed, cleaned, and repacked with grease to prolong their life. Aside from lasting longer, serviceable bearings are cheaper to replace. However, over a lifetime of service, it may add up to maintenance services/costs. Unfortunately, the majority of vehicle manufacturers do not offer serviceable bearings anymore. Years ago, the Ford F-150 and Toyota Land Cruiser used this style of bearing. The biggest drawback of tapered roller bearings is improper maintenance. Overloaded or improperly pre-loaded bearings wear prematurely. Improper grease packing is another issue when it comes to maintenance.

Wheel bearings provide a mounting point for the wheels and allow the wheels to spin. Wheel bearings are either a tapered rolling bearing design or a ball bearing design. Ball bearing designs are either press-in or bolt-in. Let's take a look at each bearing design in more detail.

Rubber seal vs metal seal bearing

Wheel bearings can exhibit growling/howling noises and show no signs of play or wear, other than excessive noise. To diagnose these, you’ll need to drive the vehicle at various speeds in turns. A left front-wheel bearing that is worn may only make noise during left turns or right turns.

If the wheel bearing is worn, you will feel a popping as you move the wheel. Additional methods for inspecting wheel bearings include using chassis ears, a stethoscope, and a dial indicator (to measure the exact amount of wear).

We highly recommend you avoid driving with a worn wheel bearing. Wheel bearings can become so worn that the hub can fall out of the bearing, causing the wheel to detach from the vehicle. This is a serious scenario that you’ll want to avoid at all costs. Additionally, a worn wheel bearing will reduce the vehicle’s handling and braking abilities. If your wheel bearing is only making noise and does not exhibit any wheel play when inspected, you may have some time before you absolutely need to replace the bearing. However, if the wheel has excessive play due to a worn bearing, you’ll want to get it fixed immediately.

For high speed applications such as cycling and skateboarding, a non-contact seal is a preferable option. Offering greater contamination protection than shields, non-contact seals do not affect maximum speed or bearing torque.

Doshielded bearingsneed to be greased

These seals are also made of nitrile rubber bonded to a metal washer but do not rub against the bearing inner ring and therefore do not have the same effect on bearing torque and maximum speed as contact seals so can be used for low torque, high speed applications. They offer superior protection over metal shields but do not provide as effective a seal as the contact type. Some bearing types are available with PE, PEEK or PTFE non-contact seals for temperature extremes or increased corrosion resistance.

Shielded metal bearings can generally withstand higher temperatures than sealed bearings. For high temperature applications 440 grade stainless steel bearings can be used at temperatures of up to 300°C. Rubber or plastic may risk melting if subjected to extreme conditions and can cause the bearing to fail if pieces melt off and enter the raceway. In these scenarios, a shielded bearing is advisable.

If you notice growling or clunking noises, vibrations, abnormal tire wear, or excessive steering wheel play, your car may have one or more worn wheel bearings. Wheel bearings are what make our wheels go round, literally. Despite their simple design and purpose, wheel bearing replacements can be costly. The type of wheel bearing used is entirely dependent on the manufacturer, and you may pay more for a repair on a luxury vehicle. When it comes to replacing bearings, you can do this repair yourself on certain vehicles, while for others, you may need to recruit the help of the pros. In this article, we are going to cover what a wheel bearing is, how it works, the different design types, symptoms of a worn wheel bearing, how to check your car for a worn bearing, and how much it costs to replace a wheel bearing.

Open bearing vssealedbearing

For applications in the food and beverage or pharmaceutical industry, equipment must adhere to strict hygiene and safety standards. In these environments, contamination protection is of utmost importance, so opting for a contact seal is favourable to ensure dust does not enter the bearing. For equipment that deals with regular wash-downs, a contact seal will also offer effective water resistance. This will stop grease washing out of the bearing, the roller or balls skidding or the creation of excess heat. Many steel bearings for this industry need to be supplied with non-toxic lubricants approved to NSF (formerly USDA) H1 or H2 standards.

Sealed bearings

Bearings are available with different types of shields and seals, commonly referred to as closures. These closures are not always essential; however shielded and sealed bearings provide much better protection from contamination and help retain the bearing lubricant.

These are by far the easiest bearings to work with, as long as you do not live in the rust belt. Issues that arise from bolt-in bearings are bi-metal corrosion and cost. If your vehicle is equipped with an aluminum steering knuckle, expect a fight when removing the steel bearing. This mostly applies to states that suffer from increased levels of vehicle corrosion and rust due to the climate. Since replacement parts come as an assembly, the cost can be higher when compared to a press-in or tapered roller bearing. Vehicles such as the Jeep Wrangler will use these bearings on the front axle and vehicles such as the Toyota RAV4 will use these in the rear.

Ball bearing wheel bearings are cheaper to manufacture and maintain than their tapered bearing counterparts. Press-in bearings require the use of a hydraulic press to safely remove and replace them. On most vehicles, such as a Honda Civic or Toyota Camry, specifically for front wheel bearing replacements, the steering knuckle will need to be removed. Removing the knuckle will require wheel alignment afterward. Due to the need for a hydraulic press, the need for wheel alignment, and the depth of the repair, most people opt to let the pros handle it. There are options such as removing the steering knuckle at home and taking the assembly into a shop and having them press the old bearing out and the new bearing in. When it comes to press-in bearings, a replacement wheel hub will be the most expensive part. Aftermarket parts such as NAPA offer full assemblies for replacement. This may be the better option, depending on how rusty or worn your vehicle is.

Worn wheel bearings shouldn't be ignored. The cost of a wheel bearing replacement in front or at the back is a small price to pay for reducing the safety hazards that come with this component wearing out.

Most of our bearings are available with metal shields. Shields are designed to prevent larger particles from entering the bearing and also to keep grease inside the bearing. They may be pressed into the bearing’s outer ring (non-removable) or retained by a circlip (removable). As the shields make no contact with the inner ring, they do not increase starting or running torque. Shields on stainless steel bearings are generally made from AISI 304 stainless steel.

Checking wheel bearings for wear is easy and only requires the vehicle or wheel to be suspended. Follow these steps to check the wheel bearing on your car:
