@@speedkar99 thanks for cutting it to pieces so l don't have to. I can see a lot of different uses for this setup other than steering a car that will come in very handy.
@@speedkar99 To me the quirky part is the twist you seem to always add referance to some relatives clothing item and also specilty tools = angle grinder. Very nice fun addition!
thank you for creating educational content that’s very approachable and beginner-friendly, while also not feeling condescending. as a car enthusiast who is in no way a mechanic; i appreciate you.
This explanation is really good, but think of how talented the people were that designed that steering and made it work flawlessly. Kudos to them and their ingenuity.
You are amongst the very best few automotive video producers on You Tube. My guess is you have an engineering background as well as being a mechanic. I am grateful for the time you put into these educational videos.
My 2020 RAV4 has this electric assist. I really like it! So smooth, center's real well, no pump, hoses, fluid and valves in the rack. Oh ya, no pump whine at full turn lock! Thank you for this video!
I'm kind of a tinkerer. There are multiple projects I've wanted to make that have been beyond my price range due to the cost of parts. Yesterday it occurred to me to see if I could use parts from junked cars. You helped me see it's totally possible. Thank you!
Thanks for taking time to dissect the system for everyone. Looking at the substantial motor armature I see why this system tends to damp rack movement. Good for passenger cars and trucks.
I'm working in the automotive industry, especially in the EPS electronics R&D field. The way you opened the PCB at 9:25 simply brought tears to my eyes 😂😂😂😂😂
hi.. pls help me.. my car has a electric power steering.. i start my car in a morning my steering wheel is very tight. in two or three minutes its going back to normal.. what is the reason..??
speedkar99 what’s going on that ye car must be scrapped -crash damage ? The components are top quality- Seems recycling components isn’t a thing where you are
Been subbed since the Toyota/Lexus programming videos. Thanks for the great content, always something new to learn. This looks like a well-made unit also.
Thanks. I kinda drifted away from the how to videos as the how stuff works videos and mechanical reviews have caught on and become more interesting since there isn't too much like that out there.
This reminds me of citroen's hydraulic diravi steering. There was no physical linkage too, a kind of physical backup linkage would apply only in the case the hydraulic system would fail. It was very comfortable for the time it has been built but it was very soft and did give allmost no feedback from wheels to steering wheel.
great breakdown. those ball drive has me thinking would make great cnc drive.. can only get this info when someone does these breakdowns. thumbs up! and great little jokes.
Pretty cool. The *stator* is the field frame, and in this case has permanent magnets. It is a six pole machine. The armature (where power conversion takes place) is the part that rotates, in this case.
Your explanations are still pretty good and if you really wanted to, you could send the logic board for the steering controller to Big Clive but he may or may not want to reverse engineer it.
absolutely perfect, i've never seen one of these taken apart to such an extent before. ¿Why do you think they used spiral balls for the translation instead of a fixed bushing?, ¿is it to make the rack able to move the motor more easily in case of failure?, or to reduce friction?
Just want to give props: straight, to the point, without any long winded diatribe on the history or power steering or how Yakumi Honda married his wife.......great job! (I hate guys that drone on and on about superfluous crap lol)
Damn! Now I can't say I don't know how electric power steering works! Love your interrogation techniques. Just the right amount of savagery and brutality. 🤪
I have a 2015 Toyota Corolla LE with an electric power steering system. My first vehicle with an electric power steering system so this video was a good explanation. I have noticed that when going down the road the steering wheel gets stiff. Its almost like its trying to return back into straight position. This happens while driving on curvy roads. I have checked the suspension, tie rods are good, axles are good, and have looked at the ball joints. What do you think could cause this?
Great video! maybe you can help me I recently crashed my 2009 Acura tsx on the front driver side it wasn’t that bad but it lock my steering wheel locked . on impact it disconnected my battery do you link the eps stopped sending signal or should I just get a new rack and pion ?
Great explanation of the major components of a rack based EPS unit! I work for a major supplier of EPS units and found the teardown of this particular unit quite interesting. Brush type motor EPS motors are not common in newer vehicles for the very reason you pointed out. They are also typically noisier and have less consistent torque output over a range of conditions. The inline rack assist (rack through the motor) is also less common. I'm guessing there was a major space limitation due to the engine mount.
I think the torque sensor's metal ring goes up and down relative to left-right motion of the steering wheel. In order to know the driver's input is left or right and EPS module turn the motor clockwise or anticlockwise.
Sheesh, everything from a full mechanical disassembly to a complete view of the underlying electronics. Thanks again for a great video!
Thanks. Gotta understand the whole system to appreciate how it works

"So I'm going to use my special security bit to take these off..." *Angle grinder fires up*
Yep, that's my special bit!
@@speedkar99 I knew it was coming but I still laughed like a hyena anyways
Just wanted to drop a thank you. You give the absolute best expalination of how systems work, with a great addition of humor and quirkiness!

This guy is amazing! Also, I've started using a toothbrush to point to everything while I teach. It's been very effective.
Thanks. Sure it's a good habit
Rapid fire details. I love it.
Everything I ever learned about how things work has come from taking things apart. The best way to learn.
This explanation is really good, but think of how talented the people were that designed that steering and made it work flawlessly. Kudos to them and their ingenuity.
Sure

It sure is mechanically simplier and more reliable. But it devoids it of steering feel

You are a very good teacher straight talking and no if and but could listen to you all day thanks

Hello, can you tell me what would be ideal EPS gear for electric vehicle ? Is it ball screw or worm gear?
Honda and Mazda do great Electric Power Steering, so much feedback for EPS.
It has to do with their suspension and tire tuning
Yep own a first gen mazda 3 can't tell the difference between that and mechanical sometimes lol
Bravo ! Very well done. I thought I had seen enough steering box's to last a life time. I was wrong.
Great video explanation. Answers a lot of questions. The real trick is putting that thing back together. Thanks!
Just got my first vehicle with electric power steering and I like it so far. The steering feel is really good and so quiet.
Nice teardown of an electric steering rack. Thanks
Thanks a lot for bringing that science to us !
Was wondering since a lot of time how the torque could be measured ^^
I just love your complete set of obscure removal tools; great video
Love the grinder too
that special security tool!!! Soooo SATISFYING!!!
Gotta love my grinder
Dude, Love how you went into the electronics of it. Cheers.
That was a great explanation of the EPS system! Thanks. Unfortunately I just keep seeing one heck of a linear actuator. :)
Thanks!
Bravo! Excellent video! Now I understand why my new OEM steering rack & pinion was so expensive...😫
Thanks! Yep they sure cost alot
Thanks for this. Love videos like this and learning. Finally started investing a bunch of tools to start. Next goal is to invest in some space
WELL DONE SIR , YOU MADE IT EVEN A CHILD CAN UNDERSTAND... GOOD JOB ...
You seriously deserve more subscribers, great job as always
0:17 That socket, by the pinion looks like an emoji jumping around ! Brilliant video, easy to understand and to the point. Subbed and binge watching !
Another good video you show us how things work in our car, thank you.
You are welcome
Great video. Full of info and concise. Loved the parts with the fancy special tools. Now waiting for the reassembling tutorial ;-)
No thanks
😂😂😂 I love that power snap ring tool! Looking forward to every video that you put up my man!💯👍
Electromechanical genius! Loved the explanation of the torque sensing system.
I love the toothbrush! 😂Excellent job!!! You are very smart AND a clear teacher!
I subscribed your channel when u hold the grinder. Absolutely technology is beautiful from inside
great video buddy
im getting a job because of your teaching realy apreciate the help
Wow, what kind of job? Glad I could help
That was awesome, I love how you dismantled every part, great video! 👍
Thanks
Great detailed description! This guy is really good!
Thanks and glad you learned something new
It’s such a shame destroying the latest technology comparatively.At least you documented it !
🤘🇬🇧
Destroying what would have been crushed as a scrap car?? I'm doing a favor here...

Superbly ordered and comprehensive
Thanks for your exalent video! Wish I had your video's 60 years ago? Keep it up!
Definitely no electric steering racks 60 years ago! But yeah every aspiring mechanic should be able to see these videos
Jeeze. You've got so many specialty tools.
Thanks for your elaborate of the EPS systems. I think my 2012 highlander has this system . I prefer the hydraulic ones.
I always enjoy the remarks about the wife's toothbrush or the brother's T-shirt, but I had a good laugh this time around about the security screw bit.
Hey it's all using what I can!
Thank you very much, now I know how it works and how to dissemble it, could you please make another video on reassemble?
🤣

The best ever
Great work on explaining it to us. Keep up the great work 👍 👏
Thanks
Seems like that Honda rack was pretty well built. You had to saw that sh!t apart.
It sure was. In fact most of the racks I've taken apart we're pretty sealed up, see my previous videos.
Superb! We hope your future videos will be full of new technological things. Good luck!
5:50 Even he’s just as amazed as we are 😲
Great video as always!
Hello sir, were still waiting for our Core rack.
I scrapped it
Great!! Now that I know how it works , I'm gonna be forced to explain it to someone, ah man... thanks a lot. Awesome video by the way!!!
Teaching others helps you to remember yourself

...it has a belt driven rack!
@@speedkar99 I'd love to see vw mk5 electric rack, as it seems it has a motor spinning all the time at certain rpm
Great video. I wish we could apply your special security bit to auto execs who replaced hydraulic with electric.
Why though? No more leaks

You'll probably need a new rack if it damaged it that bad!
Nice!
It would be interesting to see one that has the motor mounted on the steering column too...
Look up from the driver footwell of a 2018+ model year Nissan Versa.
Great explanations........Lets see you reassemble it 😉
Good one kept me focused as usual.👍
Thanks
Very educational, thank you.
You welcome
Keep up the good job mate!
Your brother's clothes though 🤣 🤣 always cracking me up!
Haha
Im definitely going to buy me a snap ring removal tool like you have. Can I use this to remove other things as well?
You should do a video on electronic throttle bodies. Always got frustrated with drive-by-wire systems haha
Haha, I found your video on the air intake covered it. Thank you for making these videos this one of my favorite channels
Thanks Yea the G35 was a pretty comprehensive video on air intakes.

Yes, and with two sensors, the computer can compare one to the other as a fail safe. Much like throttle control, two parallel inputs.
Yes and there's two coils inside the Sensor oppositely wound
Very cool explanation!
Thanks
