Put a container under the gearbox to let the fluid drain. Disconnect the pressure and return lines. There is a bolt with a nut that goes through the steering coupler that has to be removed. Jack the car up on the driver's side. There is 3 bolts that come through the frame that you will have to remove. Do every thing in reverse to install the new one.jd
you have 2 hoses .a pressure line and a return line .the pressure line is steel while the return is rubber hose.
First, gauge connect with pressure line and return line. then turn on engine. you will see the rate of flow and pressure on gauge.
Usually the leaks are at the high pressure line or the return line of the power steering pump. Tighten all the lines at the pump.
your power steering fluid return line, also known as your power steering low pressure line, may have a hair line crack in it and need to be replaced.
Power steering systems can be diagrammed into two chief components. These are the power steering pump and the rack-and-pinion steering gear. The power steering pump sends pressurized fluid into the rack which moves the gear actuating the tie-rods, which moves the wheels in the desired direction. The power steering pump has a low pressure return line and high pressure out one.
High pressure at the rack is 14mx1.5 Return line is 16mx1.5 Now try and get them to not leak.
the return lines are 99% of the time the ones with the smallest diameter.(also are not bolted down like the high pressure one)
If it's the larger hose(pressure hose) it has to be replaced as a unit. The smaller(return hose can be pieced together with a plastic barb.
Firstly you need reservoir for hydraulic oil from there goes one line to inlet port of hydraulic pump (which is driven by a engine or electric motor) then the high pressure port from hydraulic pump goes to hydraulic steering orbitrol, which is connected by a shaft to a steering wheel and has usually 4 ports. One port is connected to a pressure port from hydraulic pump (high pressure). Second port is return line to a reservoir (lower pressure). The other two ports are lines that goes to a hydraulic steering cylinder (which delivers the turning force to steering wheels). Operation: When the hydraulic pump is running and has pressure on outlet port the hydraulic oil flows through hydraulic steering orbitrol and back to reservoir. And when you apply turns to a steering wheel the hydraulic steering orbitrol redirects specific amount of hydraulic pressure to a hydraulic steering cylinder and there you have a turning force. -_- max
I don't know mutch about a Lexus but the rubber hose is should be the return line. the pressurized line should be metal or steal bradedAnswerhose that connects directly to reservoir, is the retrun hose the pressure hose goes from pump to steering
Normally a High Pressure hose will have bigger hydraulic fitting than the low pressure or "return". In fact if the low pressure hose has been serviced sometime it will just have a standard hose clamp on it.
