Alignments are an equipment-intensive business. Purchasing this equipment is often done with the state-of-mind of “who is the least expensive.” But, “least expensive” is a relative term that can be narrow or broad in definition and scope. Least expensive can be looked from two different perspectives. Short-term is looking at just the one-time purchase price.

Replacing Hubs with Wheel Speed Sensors

By Larry Carley, Technical Editor When engineers came up with the idea of putting the wheel speed sensor (WSS) and tone ring inside a sealed wheel bearing hub assembly, it seemed like a great idea. The sealed environment would help protect the sensor and make it less vulnerable to damage or contamination from the outside

This heat must be eliminated, otherwise the engine will overheat and self-destruct. The water pump keeps coolant circulating between the engine and radiator to get rid of the heat. The pump
