incredible. it was so clear, well timed, prepared, to the point, just incredible, people with natural teaching abilities dont come often.

After wasting way too much time trying to find out how power steering works, I found this. Thank you very much for the very informative video and your Star Trek references were fine.

That device you mentioned helps the fluid flow valve return to center.

I've been replacing seals on these gears and I've been swapping these gears for 45 years and until now have had no idea how they actually worked. Thanks for educating me.

You taught an old dog something new. Awesome description of operation. 👏🏼👏🏼👏🏼👏🏼

Great explanation overall. There is one slight problem and it has to do with the components you were unsure of at the end. If you are turning the friction on the outside of the sleeve is enough to cause the misalignment and open the valve as you described. When you stop steering the spool/sleeve combo returns to open center as you described. However, it’s the sleeve that rotates to catch up with the position of the spool. The springs you mentioned at the end are centering springs which provide the force required to re-align the spool/sleeve. That’s why the power steering will shut off at any wheel angle is your angular velocity is zero.

Thumbs up right to the point and an extra bonus for Star Trek

Your a lot smarter than I look . For the first time, I have an understanding of how these things work. Thanks!

What a hidden gem! Nothing useful comes up when searching recirculating ball steering but then this thing gets recommended! That was a really well-done explanation, thank you!

Excellent description of how this works! I love the detail and the cut open steering gear. Makes it very easy to see what is going on! Thank you for the videos!

I predict this will be one of the biggest channels in the history of KZfaq wants the word reaches the masters you guys are absolutely incredible

Wow! Thank you for being so clear and concise! This is by far the best description and explanation ever and I’ve been in this automotive life since I was 10 lol! Thank you!

Nailed it bud. I hope you keep videos coming. Thanks a ton helps immensely

Picked up a used one for my dodge 2500 to rebuild and I've been dying for an explanation of its guts. Thank you, subscribed.

Thanks! This was excellent and very clearly explained. It really helps me when I can fully understand how components work before I work on them so I know how to work within their limitations and design.

Thanks Josh, This is great. I'm debugging a steering problem and this kind of information and rare and essential to avoid just throwing expensive parts at the problem.

“Yeah you may want to watch this video a couple times” that hit me personally 😂 this is a great video thank you for the time it took to make it! Some much info

Where has this been?! Life saver!!

Thank you for the excellently executed video! I've been searching for Hydro Assist diy instructions for my 2006 F250 I'm going to hydro assist with my 40" tires for moose and caribou expeditions in Alaska and this is a great *assist* in that process. 👌

Absolutely fantastic work. Seriously.

Thank you sir! You did in 8:04 what was taking me close to an hour. Your sense of humor was better received than mine also.

Nice job, most importantly is how well you cut it in half

Fantastic explanation! Awesome work.

Great explanation Josh! Thanks!

Great video, explained everything very well. Thank you for posting it!!

Super informative video! Thanks for taking time in explaining.

Excellent chalkboard explanation! Also...."I'm an Engineer, not a miracle worker." Live long and prosper.

Well done! Very good engineering analysis.

Appreciate the comedy made the video more enjoyment and yeah it was confusing but you explained it well thanks again

Power steering is so much more complicated then I thought it was. Omg that poor little deflection rod plays such an important part

Great job, you made it very easy to understand! Thank you!

Im about to replace my seal gaskets on my gearbox 1978 460 engine F100 Lariat.Great explanation.Merey Christmas from Houston Texas.

Great vid, great info and laughs. Kudos for all that editing!!! Came out a great vid

Great content hope you stay at it brother I just found your channel I own a 2001 f250 7.3 and ready to install a new gearbox

this is what I'm watching before my Canadian red seal (national) exam in automotive, thanks man and God bless bro

Awsome and very simplified for my understanding!

Y'all rock for this.

Good video and great explanation.

The best video explaining the function of something ever! Subbed!!!

Good explanation, this was very interesting. Great cut out on the gearbox.

The clearest explanation. Thanks a lot.

Great video Bro, Really appreciate the effort, Now I know how this thing works

Thanks for this, it was ultra helpful and really informative

best explanation on KZfaq. thank you

your star trek impersonation is spot on. people give me flack for my impersonations too , but I ignore those fools, as should you. Keep the faith and may the force be with you. ( Over time , I have found out that it's perfectly okay to mix and match star trek and star wars impersonations, language, etc.. If it annoys anyone I say send them to their mother in law's Uranus. " I think she's gonna blow , captain.". " It's about time, Scotty, cuz her daughter's sure don't.". ( Intergalactic humor and not much of it.)

excellent explanation of these steering units thank you

Thanks for the show and tell.

This is a complex topic. Great explanation

THanks for explaining, very easy to understand this way

That’s a really good explanation man. Thank you!

Awesome tutorial on how a steering gear box works.

Excellent explanation. I am researching hydro assist and it's difficult to find an actual explanation on pirate4x4 or other sites beyond "drill here". I actually feel like I can take apart any steering box and figure out where the assist ports need to be drilled after watching the video. Thanks!

This is the best video in the last fucking 50 I've watched on this

Thanks Josh, great video!!

Excellent description of the Saginaw steering box. You need more subscribers, I just subbed.

The best explanation on power steering rotary valves.. Thank you

finally a good one! It was just amazing....

Great video! Entertaining and attention keeping as well!

Very nice! I have wondered about these. Pretty complex

Great video! very well explained

Fantastic video. Best

wish I'd had this video to reference when i was doing my apprenticeship. awesome video dude!

Excellent explanation

thanks man, you are make me understand how power steering work subscribed and like the video, also ill use your vid to explain how power steering work to my friends

Thank you sir for sharing your knowledge..take care

AWESOME VIDS! You are a damn good teacher :)

Nice one mate, this helped a lot

You Created a Great Tutorial !! Thank You 🙏🎼🌹🎵🎶🛠🔥

CONGRATULATIONS. VERY DIDACTIC AND EXPLICIT. THANKS

Holy crap dude. That was perfect. Maybe not the "Scotty" but exactly what an explanation should be. Thank you.

Great tutorial my friend! I think this just told me what happened to the stering box in my mothers tractor, she sheered thebinput shaft, wonder if I can find just the shaft.

Awesome video my man. Thanks for the help! Liked and subbed.

Interesting video, ,thanks for sharing

Thank you for this. Seriously.

Good work!!!

Thanks for the excellent video!

Thank you very much for this great video.

Very good video sir

Wow! Very educational.

great explination and its never the wrong time for a star trek joke;)

Great video c, thank u!!

Fun fact: that rack/gear has an adjuster screw to take up the slack between the teeth when it wears out. And if you over tighten it by accident, it can permanently ruin the mechanism. So yeah, don’t go poking around your steering gear with screw drivers. Let a professional adjust the steering gearbox if needed.

Good video! 👍

Great!!!! Such a nice video!

Man I really thought that this video will be boring but oh boy I was mistaken this was very informative.

thanks for your great explanation,

Great video, very helpful!!

Nice job good communication skills.

Well done

Very interesting video

Great job and my wife loves the Star Trek part.

Good explanation.

Nice explanation

610: At time point 7:40, you ask what that spring clip does. I would like to try to answer that question. Back about 4:20 you have a very nice drawing of the valve, with the inner sleeve, the outer sleeve, and the fluid flow paths. You show the inner part, which is all white and blue lines and arcs, and the outer sleeve, which is white and red and yellow and green. The inner sleeve (blue and white part) MUST be connected to the steering wheel via the shaft in the middle of the steering column. Because this inner sleeve is connected to the steering wheel, it can turn perhaps 1 and 3/4 turns in each direction from center. If the outer sleeve is stationary, which it is not, the pressurized fluid would alternately be directed to the top of the piston and then to the bottom. Additionally, every 45 degrees of steering wheel rotation, the white part of the inner sleeve would absolutely block the flow of the pressurized fluid altogether, causing maximum pressure to build up in the high pressure hose and back onto the pump. Put another way the sequence of events would look like this, 1) pressure would be directed to one side of the piston. Then as the rotation continues, 2) the supply port would be covered and the pressure would rise to maximum. As rotation continued 3) the supply port would deliver fluid to the other side of the piston. Then 4) supply fluid would, again, be blocked completely. But this is not what happens. Instead, that outer sleeve "follows" the rotation of the inner sleeve and cannot be allowed to go too far out of time with the inner sleeve, one way or the other. There has to be enough relative motion between the two sleeves so that fluid can be directed properly, per your description. But there can be only so much relative motion between the two sleeves or the events I described above will happen. In other words there needs to be a little bit of play between the two sleeves, rotationally. The spring clip that you asked about, I believe, holds a pin into a hole in the input shaft. The outer sleeve is machined in such a way so as to not be rigidly tid to the input shaft, but to allow for a little relative movement between the input shaft (along with the inner sleeve), and outer sleeve, so that fluid can be directed as needed, but not so much that it can get "out of time". I believe the two sleeves are made so that the pressurized fluid will eventually return them to a relatively "centered" alignment so that when the steering wheel stops turning, the fluid flows through the valve without putting pressure on either side of the piston. Ideally, the outer sleeve rotation would be coupled to the turning of the output or sector shaft and not to the input shaft. This would allow for a more perfect positional feedback. But it would be difficult to implement. Further, the seals between the outer sleeve and the case probably provide a slight amount of friction to help slow the movement of the outer sleeve to help with the relative motion that directs the fluid. The pin under that spring just keeps the relative motion from getting too large.

This was the best explication I’ve seen that’s bud

That was awesome!!! Thank you!!!

well i was lookin to find out what thar adj does on the top,ie what does it tighten up inside and can that part get so bad that it cant adj whatever needs to be adj anymore

Damn, this is an old video but what the hell, Thanks for this i'm currently in school and this helped alot!

Awesome explanation!! Thanks..

Great video, I'm having trouble with my power steering I've been through 3 pumps and still no power steering ? What do you think ? Thanks
