Unlike electric power steering, hydraulic power steering has been around much longer and requires fluid for operation. Unsurprisingly, electric power steering is equipped in electric cars and thus, ...

Your power steering fluid serves a few critical functions. Its primary function is to turn the steering wheel via hydraulic pressure. It also acts as a lubricant for the pump, steering pistons, valves ...

WEST LAFAYETTE, Ind. -- Researchers at Purdue University have shown how to reduce fuel consumption while improving the efficiency of hydraulic steering systems in heavy construction equipment. The ...

It's important to follow your particular vehicle's maintenance schedule, but a general rule of thumb is to flush and replace the power steering fluid between about 40,000 and 80,000 miles.

DSA is a computer-controlled hydraulic variable-assist steering system that makes GM HD pickups feel just as nimble as their half-ton counterparts, which have programmable electric power steering.

The power-steering pump pressurizes the hydraulic fluid that helps the driver turn the steering wheel. Signs of steering-pump failure include leaks, noises or decreased assistance while steering ...

Rack and pinion steering systems work using a few key components. First, the system needs a power source. In most cases, that's either an electric motor or pressure created by hydraulic power ...
