Smooth Roads Ahead: Making Wheel Bearing Jobs Work for Your Shop

Wheel bearings are safety-critical components which feature precision engineering, robust construction, and a long service life. However, all wheel bearings will eventually need to be replaced. Wheel bearing or hub assembly replacement can present a number of challenges to technicians. This could be due in part to bearing design, construction, corrosion buildup, and/or replacement parts …

ADAS 101

ADAS 101 introduces students to Advanced Driver Assistance Systems (ADAS). The two lessons will inform students on the theory and operation of ADAS systems and the sensors that make these systems function. Also, we will cover why these systems need to be calibrated and the tools to perform a calibration. Approx. 10 minutes Sponsored by:

Reading Spark Plug For Oil Problems

If the spark plugs have a matte black or grey appearance, it could be carbon fouling —something typically caused by a fuel mixture that is too rich. In this video, we look at how to interpret spark plug electrode and insulators appearance to diagnose fuel conditions.  Approx. Course Time: 5 minutes Sponsored By:

Spark Plug and Coolant Leak Indicators

Internal coolant leaks can foul a spark plug and cause a misfire. The problem could be a leaking intake manifold or a head gasket. In this module, we cover how the appearance of a spark plug changes when coolant is leaking into the combustion chamber. Approx. Course Time: 5 minutes Sponsored By:

Measuring Brake Runout

Always check runout in the hub flange and rotor as part of any brake job. You may think you’re saving 10 to 15 minutes by not having to use a dial indicator and a micrometer, but your chance of a comeback can dramatically increase. In this module, we show how to setup and use a …
