Exam 8: Wheel Bearing and Seal Service

One way to isolate a wheel bearing noise from a transmission noise is to drive the vehicle at the speed at which it is making the noise and then shift into a higher or lower transmission gear while _________.

When bearings are used in pairs, the individual tapered roller bearing assemblies are generally referred to as:

In a 3/4 floating axle design, there is a single bearing assembly (usually a ball or ________ style) between the outside of the axle tube and the hub.

Faulty bearings creates an unusual noise which usually can be heard once the vehicle gets up to _____ mph.

Tech A says that packing a wheel bearing assembly can be done by hand with proper results. Tech B says that packing a wheel bearing assembly with a bearing packer will get the proper results. Who is correct?

Two technicians are discussing how to install a replacement tapered front wheel bearing. Tech A says when installing a bearing race you should use a 5 lb hammer and a brass drift. Tech B says that you should use a hydraulic press or a hammer and bearing race installer, carefully drive the race until it is fully seated in the hub. Who is right?

In case of serviceable wheel bearings, the maximum allowable play is:

_________ refers to the absence of clearance in the bearing and the specified amount of pressure forcing the bearing components together.

It can be challenge is to distinguish between a wheel bearing noise and a tire noise. The best approach to this problem is to drive over different road surfaces. Tech A states that if the noise changes, it is likely a tire problem. Tech B states that if the noise does not change, it is likely to be a faulty wheel bearing. Who is correct?

Which component of a wheel bearing holds the rollers or balls in place?

Which type of bearing is recommended for a vehicle which is subjected to heavy loads and thrust during turning around the corners?

Tech A says that the best approach to determining if a noise is a wheel bearing or tire is to drive over different road surfaces such as asphalt and concrete. If the noise changes, it is likely a wheel bearing problem. Tech B says that the best approach to determining if a noise is a wheel bearing or tire is to drive over different road surfaces such as asphalt and concrete. If the noise does not change, it is likely a tire problem. Who is correct?

All of the following can be caused by a loose or worn wheel bearing, EXCEPT:

Tech A says that the wheel bearing can damage the wheel hub or spindle/axle in a vehicle. Tech B says that bearing failure involves the race spinning in either the machined bore of the wheel hub or on the surface of the spindle/axle. Who is correct?

________ can be damaged from excessive loads such as overloading the vehicle, shock loads such as hitting a large pot hole, improper adjustment, or just plain wear over time.

Tapered roller bearings are used typically in what configuration?

Because tapered roller bearing assemblies use tapered components, the wheel bearing assembly must be adjusted to have the proper ________ between the tapered rollers and races when the bearing assemblies are installed.

Tech A says when installing a bearing race you should use a 3-lb hammer and a brass drift. Tech B says that when installing a bearing race you should use a 3-lb hammer and a 3/8" drive extension. Who is correct?

Which of the following is a component of a typical wheel bearing?

What term is used to describe the outside component of a wheel bearing that has a smooth, hardened surface for rollers or balls to ride on?
