I NEVER knew how this worked!! You have the BEST way of describing how things work. Almost too quick, but fast enough to not lose people like me with short attention spans. Brilliantly done!
The most amazing thing about power steering to me is the simple fact that they always tend to be so reliable. Even when they do go out it usually takes a long time.
Been a mechanic for pushing 30 years now. Always had a pretty good understanding of what's going on inside a rack even though I never had one fully apart. This was a good video. In addition to being very informative, it was also good instructional lesson on how to use the proper tool for the job.
I retired from a Ford dealership. In old days we had to reseal power racks... I got really fast at it after doing a few. Great video and great explanation on the torsion bar input shaft.
Holy pepperoni power steering is more complicated than I expected. The genius of the torsion bar system is truly amazing that someone designed that decades ago. My tacomas pump is whining and in a few hours I coulda been fixing it I spent learning the exact way the system works. Quite fulfilling to learn. Thanks
Your a great teacher. Your English is awesome. You are the first person that don't say "um" between words. I can really understand your video. Specially with your details description on each components and it's purpose. .
I'm sold, straight forward explanation, 8 min vid of your vid is typically 15-20 min from the other guys without the extra movements and talking. Love the dirty toothbrush pointer.
I've been learning everything I can about cars for 15 years and never knew this. I had no idea that power steering was so complex. Thanks for making such a great video!
Excellent videos. You sir, gave me the courage and instruction to perform a complete timing belt and water pump service on my 1MZ-FE V6. So... thank you! I saved over $1500 that I would have spent at my Lexus dealer.
I am a student at universal technical institute and this is far more helpful than what I've been learning in class. thank you and keep doing what your doing
speedkar99 I’m with Eddy. I’m not really a car guy but your videos are incredible. I watch a lot of videos on how things work and this is some of the best stuff I’ve seen regardless of subject matter
These videos are amazing! lol I love the humor it amazing... and the toothbrush hahahaha I literally can't stop laughing but i'm trying not to because the information is so good.. well done explaining something that is very technically complex in such a digestible manner. Your videos are great keep up the good work.
As a former rack and pinion steering engineer for an OEM, I commend you for your explanation. Very well done. The only correction is that the steering fluid flows thru precision metered lands on the edges of the slots in the input shaft.

One of the best explanations of rotary control valve operations. Many youtubers skip that part bcz they don't understand themselves the operation and importance of this part as the heart of power steering system.
I worked in TRW, one of the largest steering gear manufacturer in the world, for 20 years working on the hydraulic steering gear. Your explanation is THE best I've seen on the Internet. I don't think some of my colleagues at work couldn't explain it as well as you did. I don't know where you got your training but this video is A+. VERY WELL DONE. IMPRESSIVE! One additional info if I may... at 6:40 where you explain the inner workings of the valve... the "slots" you see on the input shaft has really tiny chamfers along the edge, called "metering edge" which is ground to micron precision, give you a precise amount of assist proportional to the "relative twist" of the input shaft and pinion. That "metering edge" is the heart of the hydraulic power steering system.
Wow thanks very much for that information and feedback, it makes sense that that controls the sensitivity. I would love to work in tier1 or OE one day!
This guy really knows his stuff. This is the clearest video on power steering I've seen. Once you get past that toothbrush, these videos are worth their weight in gold.
Awesome video!! I just found your channel and i think we’re similar in the sense that we’re very “resourceful” when we work on our machines and we aren’t afraid to tear them apart to see whats inside. Thats the best part about working on cars. There are so many parts working together and they’re all fascinating. i try to impart that enjoyment on friends when they get work out of me but it takes a specific person to understand and care about whats going on instead of just mindlessly throwing parts at a car to fix a problem - or worse yet, taking it to the dealer for something that otherwise would cost no more than the parts themselves, a morning or two on a weekend, and a pair of dirty hands.
I've always scratched my head at how power steering works, even after getting so-called explanations. This video is the first COMPLETE explanation I've seen. Thank you for making it.
Yes, I don't know what there is not to like about this video, why would you even watch it if it is not to your liking or interest is beyond me? There are plenty of weirdos out there.
I can't thank you enough for the fast pace and high info density. When I'm looking for this kind of video, it's usually because I'm in the middle of a repair and I'm stuck. On most channels I end up watching at 2x speed just to get to the info I'm looking for. Thank you for taking the time to research, plan, disassemble, film, and edit!
This is a fantastic description of how power steering works. Even a complete amateur like me could understand it all first time round.. You are a brilliant teacher.
That's a really great video. One more bit of information: The control valve actually lets the steering pump free-wheel by letting the fluid flow easily from input to output when you're not using the steering wheel, so it's not all that in-efficient. It doesn't put much load on the engine until you begin to turn the steering wheel, and the control valve then blocks free-flow of fluid and forces it through the steering rack piston. That's why the engine RPM (at idle) drops a little when you turn the steering wheel, and if you turn the steering wheel all the way against the stop, the rack piston stops taking more fluid which causes the pressure to rise rapidly until the overpressure relief valve in the pump begins to let the excess fluid bypass the control valve. That's the hissing sound when you turn the steering wheel all the way. Thanks for the great video! I enjoyed every second and I enjoyed the fact that every second had something useful in it!
@@speedkar99 Oh, I see what you mean. Although with electric, you have to consider it's pump - an electron pump - aka the alternator - and it has to be larger to handle the increased load, and it's always turning and always sending full voltage to the electronic control module, which wastes some of that power all the time. The larger alternator puts more of a load on the engine, all the time. (Yes, a larger alternator has larger core losses even when producing small currents. Look up core losses in generators.) So the increase in vehicle efficiency isn't as great as you'd guess. But sure maybe you can get a couple percent better mileage - which could save you a few dollars a year - but my guess is that your entire savings is gone when you then also take into account the greater cost EPS to start with, and the greater cost when it dies and you have to replace it, and the much greater chances of it breaking: It's a very complex system involving wires, semiconductors, electromagnetics, and a computer chip more complex than the one that first landed on the moon: The average rate of failure and average yearly cost of EPS repairs per thousand cars FAR exceeds that for engine driven hydraulic power steering, and this cost severely consumes the slight fuel savings brought by EPS. Hydraulics last an extremely long time, are very simple, and nearly bulletproof.
ew.. dude, you also use his underwear, he wouldn't be making an appearance holding the seat down right? I bet you're Latin, Latin moms use old underwear as cleaning rags. represent La Raza! LOL.
Talk about Modern Marvels, it's truly amazing how engineers designed something as complicated as a "Rack and Pinion" steering system. Great Teaching Tutorial, Thanks !!
WOW ... the best (thorough and concise) explanation and demonstration of how a power steering (rack and pinion hydraulic) system actually works ! Bravo and thank you very much.
Thanks, I’ve suffered terribly with bad racks, leaky, hard to steer, etc. Now I know more. Didn’t know those holes the fluid moves through were so small by the pinion gear. Easy to clog.
Just replaced 2 racks in my truck because of defects in rebuilding process, someone be was sleeping on the job... Thanks for the education in how racks work! I'm subbed!!
You did a great job explaining the function of the hydraulic control valve. Some terminology was not correct, like lateral, but the hard part, you did a fantastic job with. No insult intended.
Very nice explanation. It deserves to be noted though, that when no torque is applied to the steering wheel, as in going straight down the road, there isn't any pressure in the system. Hydraulic fluid is flowing through the valve body, but not against any resistance. The pump and hydraulics are freewheeling, as it were. This is why you only hear a load come on the engine when you turn the steering wheel (like when parking, or other low speed maneuvering).
Ive looked at schematics a long time ago, but never heard about the torsion bar, so i could never quite understand how it worked. Very informative video!
Thank you , thank you! Best video on power steering that I have seen; your approach, humor and excellent point by point explanations are spot on. The magic happens at 5:50 👍
I work as a mechanic and I still have a lot to learn. My friends think I'm this master mechanic, I watch his videos and I feel like a noob hahaha. Excellent videos, its nice to see how components actually work vs. just replacing them and moving on. I have replaced about a dozen a/c compressors this summer and many of them leaked. Watching his a/c compressor video makes me wonder if an o ring or gasket was bad. I know time is money and I work at a very small "ma and pa" shop, but I can't help to think how many parts could be repaired and work just as well if not better as a replaced aftermarket or junkyard part. Keep up the very informative videos! And tell your brother to keep buying more socks haha
Finaly someone that gets on point and actually explains what we were here for and that's how steering rack work and how hidraulic (servo) steering works. ❤
Hey, its the guy reviewing the TH-cam teachers videos. My goodness. Such a great explanation especially with the diagram. I like how you had three videos that talked about ABS system. 10 out of 10 my friend. 10 out of 10.
Yes, sir!....the human heart is so inefficient.......it keeps pumping when you're just sitting there and not thinking about anything :) great video, informative and entertaining as heck, keep up the great work!!
Excellent presentation! I recently had the rack and pinion replaced in my old 4Runner.....seal was leaking....Had no idea of how this worked, so now....thank you!
Thank you for this. I always knew how it worked but had never seen the actual "guts". That valving operates with less motion than I thought. I think that there is not a lot of pressure in the system in the neutral position since the fluid is just routed through the valve back to the reservoir . If there were a lot of "do nothing" pressure' there would be very hot fluid.
Excellent straightforward video!!! I have a steering rack problem on my 2006 Citronen C5 (260,000km) that is not covered by anything I have managed to find online! A few years ago the driver side front tyre wore out very quickly. I found out it was due to the rack on the pinion side had a vertical play. I could by hand move the rack up and down about 10mm wich caused the wheel to move, probably to one side while accelerating. And towards the other side when braking and decelerating... Causing the tyre to wear out almost evenly (in opposite to wear from faulty toe-adjustment) I opened up the "Rack damper screw" (some places called Yoke adjustment screw/plug) and applied new greas on the pinion plunger, and tightened up until the play disappeared. All have been fine until the driver side wheel now again have a bit of side to side play. I tried to tighten up the plunger a bit more, but that causes the steering to bind. And when backing of just a little so the steering wheel moves smooth again, play comes back.. My first thought is that the plunger that supports the rack against the pinion are worn, but I have not seen any spare plungers for sale. Is my thinking correct the also the plunger can wear out as with the bushing on the opposite side? Cheers Gunnar
This is a very well presented video. The explanations and drawings are done so well that a person with limited mechanical knowledge can grasp the concept of power steering. 👍👍👍
Thank you! I watched several videos on the subject but your hands on tear down coupled with a well worded explanation of the inner workings of each component put an end to my guess work.
I NEVER knew how this worked!! You have the BEST way of describing how things work. Almost too quick, but fast enough to not lose people like me with short attention spans.
Brilliantly done!
Thanks very much for your feedback!
I didn't know myself before cutting it open to find out.
The most amazing thing about power steering to me is the simple fact that they always tend to be so reliable. Even when they do go out it usually takes a long time.
Man, you are the best! Came in knowing nothing about steering and left knowing something! Amazing crash course!
Thank you so much!
i love how now you can learn more on youtube than you can in any class
Sadly it's true
Love how you explain things so plainly in your videos with toothbrush and all.
+Abdullah Al-Munim Thanks - I guess alot of people like my style
Exactly the tear-down I was looking for! Thanks for going into detail about the torsion bar and showing the diagram of the fluid flow.
Glad it helped. I too had to sit there and figure it out myself, it's hard to understand but not seeing the real thing.
This is hands down THE best explanation of a rack and pinion that I've ever seen!!! Great job sir!

This helped with mechanic college classes so much, youre a life saver. Thank you 🙏
Hey, its the guy reviewing the TH-cam teachers videos. My goodness. Such a great explanation especially with the diagram. I like how you had three videos that talked about ABS system. 10 out of 10 my friend. 10 out of 10.
Good explanation. I knew in general how it worked but seeing the various pieces as you took them apart made everything clearer. Thanks.
+Russel Brooks Hey thats what I'm here for, thanks for the feedback.
GREAT JOB!! FULL, Thorough, Explanation in just a few minutes.
Thanks. Short and to the point is my style
Yes, sir!....the human heart is so inefficient.......it keeps pumping when you're just sitting there and not thinking about anything :)
great video, informative and entertaining as heck, keep up the great work!!
Excellent presentation! I recently had the rack and pinion replaced in my old 4Runner.....seal was leaking....Had no idea of how this worked, so now....thank you!
Thank you for this. I always knew how it worked but had never seen the actual "guts". That valving operates with less motion than I thought. I think that there is not a lot of pressure in the system in the neutral position since the fluid is just routed through the valve back to the reservoir . If there were a lot of "do nothing" pressure' there would be very hot fluid.
Excellent straightforward video!!!
I have a steering rack problem on my 2006 Citronen C5 (260,000km) that is not covered by anything I have managed to find online!
A few years ago the driver side front tyre wore out very quickly. I found out it was due to the rack on the pinion side had a vertical play. I could by hand move the rack up and down about 10mm wich caused the wheel to move, probably to one side while accelerating. And towards the other side when braking and decelerating... Causing the tyre to wear out almost evenly (in opposite to wear from faulty toe-adjustment)
I opened up the "Rack damper screw" (some places called Yoke adjustment screw/plug) and applied new greas on the pinion plunger, and tightened up until the play disappeared.
All have been fine until the driver side wheel now again have a bit of side to side play.
I tried to tighten up the plunger a bit more, but that causes the steering to bind. And when backing of just a little so the steering wheel moves smooth again, play comes back..
My first thought is that the plunger that supports the rack against the pinion are worn, but I have not seen any spare plungers for sale. Is my thinking correct the also the plunger can wear out as with the bushing on the opposite side?
Cheers

This is a very well presented video. The explanations and drawings are done so well that a person with limited mechanical knowledge can grasp the concept of power steering. 👍👍👍
Glad it helped
This is wonderful, the first time I see every detail of the Steering rack, thanks buddy
Thank you! I watched several videos on the subject but your hands on tear down coupled with a well worded explanation of the inner workings of each component put an end to my guess work.
You are welcome, thanks for watching, I have alot more teardown videos coming soon.
You don´t need fancy special effects and computer graphics to make a great video. Thumbs up to you.
A good video forever until TH-cam runs. Thank you. Keep posting
Thank you for the great description of the power steering system operation.
Glad it was helpful!
