Power Rack and Pinion Steering System

Here's how a hydraulic steering rack works to turn the wheels on your car.
Hydraulic steering has been used for decades to provide assist to drivers turning the wheels of especially heavy vehicles.
Fluid is pressurized by a hydraulic pump and is sent to the rotary valve via the high pressure hose.
Depending on the direction, the fluid is pushed into the opposite side of the cylinder housing, pushing the piston. The piston is connected to the rack, which connects the tie rods and hence the wheels at the steering knuckle.
Its all explained in the video, Thanks

[@OluwaseunOlanlokun]

Great and very clear video. I perceived i interchanged the high pressured lines at the rotary valve section during rack installation, Please i like to know if the the steering system will still work fine ( i mean not hard to turn) if I leave it that way?

[@automotivespot]

Dear both the high pressure lines are same, so there will be no problem (hard steering) if you interchange these lines. The most important thing is tha if you Interchanged the place at valve you must interchange its place at rack too.

[@user-fc3fk1sg7l]

thank you so much sire very good explenation also you should mention about how the torsen bar work because its the key element of the rotatory valve when the driver exort too much force one the wheel the trsen bar would twist and it will make the orifices in the grooves inside to line up so the fluid will be flowing to the appropriate line depending on if that twisting is to the left or to the right thank you so much very nice video keep up with these videos they are so good and i love them i would like if you mad a demonstration about the automatic transmission and the torque converter thank you so much sir

[@harrys2960]

on my Sonata 2002 v6,16", there is a leak in either L or R metal line, I just want to replace the hose/Line Instead of changing the whole Rack & Pinion , which the mechanics do.What do you suggest.??

[@automotivespot]

No need to change the whole rack and pinion, if the leak is in the pressure line, just replace it with a new one. Thats it

Good explanation, but what I need to know is where does the fluid come from. Storage? How does one refill in a Toyota belta 2007 model, s2z engine?

[@automotivespot]

Fluid is stored in a small tank/bottle which is fitted under hood, it has marks of low and high fluid level, you can refill it from there. Thanks

[@pratikchandu7848]

I have tata Indigo car, the same hydraulic system is in my car, and my steering is hard, can you tell me the reason behind this

[@automotivespot]

You must check for leakage, if there is a leak, definitely it will result as a hard steering, the second thing is to make sure there must be enough grease in joints to make the steering smooth, Thanks

[@pratikchandu7848]

@@automotivespot there is no leake in the system, i will check the grease

[@automotivespot]

Also check if the oil is contaminated.

[@richsmith9063]

Good explanation. BUT please explain how the return pressure to the reservoir gets reduced from the pump ~1200 PSI down to LOW pressure

[@automotivespot]

There is a built-in spring loaded pressure relief valve, which operates when the pressure hits the preset limit. I hope you are clear now.

[@galihjatimerapi]

[@murtazaali3275]

Thanks Nice and clear demonstration, I have a problem, when I park the vehicle for 8 hours the oil level reach to maximum and once engine starts the oil level becomes at min level... please advise what could be the possible reason...

[@automotivespot]

The most likely reason for the power steering oil reaching the maximum level when the vehicle is parked for 8 hours and then going to the minimum level when the vehicle is started and driven is that there is a leak in the power steering system. When the vehicle is parked for an extended period, the power steering oil settles at the bottom of the reservoir, and any leaks in the system allow air to enter the system, which causes the oil level to drop. When the vehicle is started and the power steering system is engaged, the pump draws in air instead of oil, which causes the power steering to feel weak or "sluggish" and the oil level to drop further

[@safecarsforyou]

Is this a hydraulic power steering and not electronic as in my Toyota etios. I had a contessa years ago but it didn't have power steering and no way to lubricate with steering box oil so I suggested my mechanic who was a bit reluctant but finally agreed to do what I told him, I wanted him to make 2 holes in the rack casing ( housing) and give two grease nipples and after packing grease the steering was smooth as butter. Can I do the same on my etios which has power steering

[@automotivespot]

Not at all, power steering has its own lubricants with the power steering oil 🛢️

[@johndao4660]

the best system why rhey replace elctrice power steer alot prolem

[@automotivespot]

Electric power is more comfo than hydraulic, secondly innovation is important

[@rajeshindia3661]

Sir, Will it damage the system to turn stereing wheel left or right without starting the car...?

[@automotivespot]

No it wll not, because its the combination of power and manual, so it will work manually in that case 👍

[@Macgarage08]

Yes it is work. If the engine not running you will have heavy steering because the pump doesn't work yet.

[@nelsonmagalangjr.1933]

Hi. Do you a have a video of how to fix leaking power steering rack? Thanks

[@automotivespot]

I haven't shoot such video, but the possibility of leakage, is due to some crack , or loose fitting or maybe the yoke is not properly fitted at its place.

[@balsonnaoshekpam5680]

Thanks Please tell me the reason of my problem Why power steering is not returning full to its original

[@automotivespot]

Sticking or binding components, such as a king pin, ball joint, bell crank or even the steering column can prevent the steering wheel from returning to center after a turn

[@OpenKitchenByShaista]

Assalam O Alikum I have a problem with my elantra car steering wheel. during left or right turn i hearing rubbing/friction sound this sound is not from tie rod bush ( i changed all bushes 5 months back) if am feeling the sound coming from horn side of my steering. how to get rid of this sound. or what is the actuall problem please reply me

[@automotivespot]

W salam. If your steering wheel is making a loud rubbing noise when turning, the culprit could be the upper bearing on the steering column itself. This can cause the the plastic on the back of some steering wheels to rub against the cowling on the steering column.

[@Hilary-ys1gk]

So does the grease on the pinion gear ever touch the seal when the turning left or right

[@automotivespot]

Yes dear, but it has no effect on it 😊

[@muhammadawais6253]

if there is oil leakage around the rubber at the valve what could be the main reason, which part need replacement?

[@automotivespot]

The reason could be a damaged or worn-out seal within the valve assembly. Typically, the part that needs to be replaced would be the valve seal to stop the leakage. It's important to diagnose and address the issue promptly to prevent further damage to the power steering system.

[@sarbjeetsingh2825]

sir i want know how fluid get stop when stop rotate steering

[@automotivespot]

Fluid remains in the chamber, till we rotate the steering wheel.

[@angelabrandonsantacruz4596]

If I have metal shavings in my power steering system should I replace my rack and pinion or flush and replace pump only??

[@automotivespot]

Metal shavings in your power steering system could indicate a serious issue. It's recommended to thoroughly inspect the system to identify the source of the shavings. If the damage is extensive, replacing the rack and pinion might be necessary. Flushing the system and replacing the pump alone may not address the root cause.

[@afzaalkhan.m]

Replacement a must
