Nettet10. apr. 2024 · Shifting between two-wheel drive and four-wheel drive modes is accomplished using a vacuum-operated system – which works by using a vacuum pump to generate vacuum pressure. That vacuum pressure is used to activate a diaphragm inside the IWE hub assembly, which engages or disengages the hub.

If a ground driver fails in the PCM, an open or erratic circuit will occur. NettetThe Integrated Wheel End (IWE) is a component on any 4-wheel drive vehicle that allows it to shift from 2-wheel mode to 4-wheel mode and vice versa. It looks and unlocks the front hub to do this. This component is … Nettet13. mar. 2024 · In 2wd, you won't always have vacuum to the IWEs.
