am working on a 94 ford ranger with gearbox, if you turn left its fine but if you turn right its really hard to turn, i've already changed the hidraulic pump and still the same! i need some tips about this please! houses?? or the box?? i got tires bidding and nothing!! i'll wait antious for your answer!! kind regards from mexico!!^.-

@@gustavolopez3659 If you feel power assist in any direction then your pump is fine. There is a valve that directs the pressure in the gear and it is what is causing your headache. I've seen those valves fail and the steering wheel won't go left or right, the hydralic pressure locks it in place. Replace or rebuild the gear.

Got a question for you if you have the time! I have a 2020 silverado 2500. Need to replace the steering gear box. The one that’s currently in the truck has the plug for the electronic steering assist as well as a mounting point for the module. The one I bought does not. It seems like I can just take off the four bolts on the end (positive feedback valve?) and swap the two pieces, can I do this?

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.

Thanks. "However, it’s the sleeve that rotates to catch up with the position of the spool." Um.... I didn't say that? I feel dumb now. :) "The springs you mentioned at the end are centering springs which provide the force required to re-align the spool/sleeve." But dosn't the torsion bar in the input shaft do that?

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.

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.

The partial gear on the output shaft isn't a pinion, because it isn't a small gear. It's a sector gear (because it is only part of a circle), which is why the output shaft is often called a "sector shaft".

Well done!! absolutely fabulous, but ONE comment. At 8:04 you are going down the elements of the valve, you SAID "Piston Top" "High Pressure" "Piston Bottom" but you WROTE "Piston Top" 2x.The cutaways you did are clean and clear. I always love those but never understood how they were done so perfect. For those that do not completely understand hydraulics, this system works off the hydraulic principle of Force x Area = Pressure. Fluid is incompressible, so any force you apply to a closed container is transferred in all directions equally. If you notice the bottom of the piston is large surface area, so if you allow in pressured fluid at 100 psi, and you have a 1 inch area, you get the force of 100 pounds of force. If you have a piston like this with three or four inches, you get to multiply the force so 100 psi in, creates three hundred or four hundred pounds of force. If you notice that the of the one side of the piston is larger than the other side of the piston because the shaft is in the way effectively reducing the available surface area to press against this would potentially lead to an imbalanced feel turning left versus turning right. One side has a bigger piston than another side. I am interested to see how this is compensated for to give a balanced feel to the turning process. Thank you so much for doing these. I am going to look for more from your page.
