Technician A says that if a tapered roller bearing is adjusted too loose, the bearing will bind and overheat. Technician B says that if a taper roller bearing is adjusted too tight, it will have too much side-to-side and up-and-down movement. Who is correct?

Both Technician A and B.

Explanation:

The tapered roller bearing clearance is too tight, the components will bind and overheat due to increased pressure. Overtightening adjustable tapered roller bearings is a common error that can lead to premature failure. If you notice a grinding or grating noise coming from your wheel or tire, take note that this is very likely caused by a bad wheel bearing—especially if the noise gets louder as the vehicle accelerates. Another revealing sign of bad wheel bearings: A car that feels loose as you drive it.

While, If the tapered roller bearing is adjusted with too much clearance that is loosely, excessive side-to-side and up-and-down movement will occur
