When establishing shaft or housing sizes the effect of differential thermal expansion must be taken into account. If thermal gradients are present or dissimilar materials are used, room temperature fits must be adjusted accordingly. Approximate thermal coefficients for common materials are available from NHBB.

Generally, a wheel bearing replacement could cost anywhere between $150 to $800. The cost will vary as per the make and model of your vehicle, part price, and labor charges in your area.

The labor charges for a wheel bearing replacement can fall between $60 to $300. And changing the wheel bearing usually takes around 1 to 1.5 hours.

However, if the wheel bearing replacement cost is not a constraint, you should probably replace both. If one wheel bearing has reached the end of its life, chances are that the bearing on the other side would be nearing its end of service life as well. In that case, replacing both the wheel bearings together makes sense.

However, like any other car part, wheel bearings can wear out sooner if you frequently drive over potholes or drive too fast over speed bumps. Water, dust, sand, etc., can also get to the bearings and contaminate the grease that keeps them lubricated.

Some housings will not work with some insert bearings. Please notice the housing notes to the right of the picture to make sure the ball bearing housing you ...

A bearing that is fitted too tightly or too loosely, or is damaged during assembly by excessive force or shock loading, may degrade the performance of your assembly. Reduce this possibility by following some general guidelines during the design of mating parts and by observing the following four cautions during the assembly process.

Wheel bearings usually have a long life span of around 80,000 to 100,000 miles. Some may last for 150,000 miles too. There’s no standard maintenance schedule for wheel bearing replacement.

Fit tolerance

Below the caution statements are recommendations for shaft and housing fits for a number of different applications and a table of recommended shoulder diameters for select NHBB part numbers.

The bearing will be subject to early failure in most applications because it may already be overloaded. This problem can be solved either by a higher radial play or looser fit.

Replacing a wheel bearing is an intermediate job that requires specialized tools and car part knowledge. If you’re not sure, it’s better to have a professional perform the replacement for you.

When you hear a growling or grinding noise from your wheels, it could indicate that its wheel bearing is failing, usually due to a lack of lubrication.

Accurate shaft and housing fits are important for proper bearing installation and operation. In ordinary applications, miniature ball bearings are used with a light load, so a light interference fit to a narrow clearance fit is usually sufficient. Light cross section bearings, such as Torque Tube and Thinex bearings, are more sensitive to shaft and housing imperfections and require looser fits than heavier cross section bearings.

Wheel bearings are a set of steel balls or tapered bearings that roll around inside a metal casing called a race. This casing is located between the drive axle and the brake discs (or drums.)

If you hear a clicking sound that increases in frequency as the vehicle accelerates, there could be a problem with the wheel hub assembly. 4. Wheel Wobble.

L = Loose fit.T = Tight fit.d = Bearing bore as listed.D = Bearing OD as listed.+Bearings must be purchased with bore and OD coding. Example: To use SSR-2 bearing in a potentiometer, the shaft diameter should be .1250 –.0001 to .1250 –.0003 or .1249 to .1247. The housing should be .3750 +.0002 to .3750 –.0000 or .3752 to .3750.

Delaying a replacement could lead to excessive vibration in your steering wheel, or you may experience your vehicle pulling to one side. A damaged wheel bearing will also strain the hub assembly, CV (constant velocity) joint, and your vehicle’s transmission.

Wheel bearings are a vital part of your car’s steering, braking, and suspension systems, allowing you to turn your wheels smoothly with minimal friction.

Interference fit

If the outer ring or inner ring face will be clamped or abutted against a shoulder, make sure the shoulder configuration provides a good mounting surface:

Some cars come with a wheel bearing that you can separate from the wheel hub, while others may have the wheel bearing as a part of the hub itself. If it’s possible to separate them, you only need to pay for the wheel bearing, which is cheaper than buying the whole new hub. That said, it’s a more labor-intensive job.

Bearinghousing tolerance

When miniature and instrument bearings are interference fitted (either intentionally or as a result of thermal gradients) the bearing radial play is reduced by an amount equal to approximately 80% of the actual diametral interference fit. Thus:
