Hi from liverpool England
So those parts essentially fix the rack in place? And it seems it's a adjustable arrangement. I may have to go back and see if this particular setup is put in place to simplify the machining process, reduce the otherwise stricter tolerance requirements of parts. It seems like a pretty smart solution that works.
Call me crazy, but, doesn't the simpler Toyota design seem MUCH more reliable over time? The electronics and the belt on the Chevy seem like a time bomb.
+Brian Day of course the simpler design will be more reliable. The Chevy steering rack may last the lifetime of the car though, which is barely 10 years or so...just check out all those 10 year old Chevy cobalts in the junkyard as proof.
Truth right there! I on the other hand, think 10 years isn't that old. My Toyota rack went out on my Lexus after 14 years/255 K miles. Wonder if any power assist racks can last that long or if the the down side to the new tech shortened life spans. Thanks for the reply!
+Brian Day New tech isn't meant to last as long as the old stuff. Cars are more disposable these days. To buy the inner tie rods for this car you have to buy the entire steering rack assembly! Therefore 10 years for a domestic car is normal. Japanese cars last longer and hold their value a bit more.
The first rack is from a Camry which is a much larger car and has the luxury of placing the motor upstream inside the vehicle. The Cruze is much smaller and I'm curious to know if the Corolla (Toyota's comparable version to the Cruze) has a similar setup?
Dude truly thank you so much for disassembling a unit .. you have the best explanation.. about the bearing .... I have a 2010 sho Taurus the steering rack is loud grinding sound I imagine I should be able to remove take it down to rack shaft and load it up with grease and hopefully get the horrible sound to go away ...
@@speedkar99 No, an engineer in CNC machinery, and these items are directly borrowed from CNC linear motion. In fact an argument could be made that electric power steering *is* a CNC machine, in a very real sense.
Another great video coming from you sir, thank you! I am wondering what happened to the electric motor that drives the Toyota steering rack as it never made an appearance in the clip though.
@speedkar99 - in 2:07 when you take the cover off, you have two rotors there both pressed onto pinion. The pinion itself is consisted of two pinions (upper and lower). Those two rotors, are simple magnets. The Pinions are pressed concentrically and are connected with a torsion bar. When turned, the torsion bar will allow a slight movement of upper rotor to inside lower rotor thus creating changes in magnetic field. Then the Sensor (which is called hall Call Sensor) reads those changes and translates this information for the computer. This system allows the EPS to "read the mind" of a driver, so the gear knows in which direction you want to turn.
Nice! Thanks for that information, pretty cool how it picks up that information. I thought it would have been a simple steering angle sensor further up the steering shaft.
thanks for the video! helps me understand my steering and suspension class better. figured there would be more lube on the Chevy worm gear looked dry to be a new car? the thing applying pressure underneath the special nut you ground off the Toyota rack is called a yoke I think. again thanks for the video.
Amazing how complicated rack and pinion steering can become with electronic assist. You have to wonder about the long term reliability of these pieces as the vehicles age.
I have had the electronic steering lock up several times in owning the car I drive. The only way to reset it was to turn off the key momentarily, restart and it began to work again. Luckily I wasn't on the freeway or a corner at highway speed when this happened.
What would you say could cause a lag in motor assist on a steering system like this? I have a 2017 Mustang and the EPS has become notchy when changing direction. It's like there's a static friction to overcome before the steering changes direction resulting in a notchy feel at the steering wheel.
@@speedkar99 well I only have 2 years and 30k on her so she should still be under warranty. I'm so heavily modded though I'm hesitant to take it in. Next thing you know they're joyriding your car around lol. Maybe that's the move though.
@@pace1786 doing modifications to your drive train while the car is still on warranty isn't wise. Different wheels, tires and entertainment system mods are ok, but anything that changes your emission controls will be an expensive issue when and if your state or country requires inspections of the emission controls as a condition of licensing the vehicle to drive on the highway. You while have to return the vehicle to stock to pass so save they parts you have changed out.
@@rewing4880 only if you live in one of them commie states that has a bunch of BS emissions regulations. Not an issue where I'm at. Also, no one is buying a Mustang 5.0 to be wise LMAOO. If I was penny pinching enough to care about a warranty I shouldn't have bought this car at all.
+K Smithers yes that would be a nice project. That DC motor had a computer behind it so my thoughts would be it would need some kind of programming to get it to work.
speedkar99 Or would it need programming? Would it be possible to toss the chip? Looks to be wires coming out the back, could you solder wires on the motor possibly... If you could make that motor work with a variable speed controller, that would be awesome!!
You can. Always run a brushed universal motor without any electronic control circuit been there. You can also run the same motor on AC too. So they are not just DC motor. But to successfully use it for your intended purposes you may have to work out the power feed connection. Universal motors come with different numbers of brushes, the sequences and order of the connection may be altered to fit the power sources, or say current type, AC or DC. You only need add a adjustable resistor setting to control the speed and hence the power output.
Sensor on steering rack is a torque sensor If there are 6 wires from it, it is likely that the car has Torque sensor 1 and Torque sensor 2 on the steering rack
I can understand working of hydraulic and elctric assisted power steering but how does the wheel comeback to neutral position automatically after turning when we let off the steering wheel
So if you use electric motor assisted rack the only thing better than hydro pump is ->> you turn the key in "ON" position without starting the motor and you still have the power assistance for turning the wheel. Still operating such motor gives the alternator more work to do from where the fuel consumption also increases?Am i right? EDIT: What's the price for OEM electrical motor+the computer controller for this Cruze? I guess 1-2 grand...
+Petar st The electric motor doesn't turn on with the key, most vehicles are programmed to have it turned on with the engine. The electric motor only draws power off of the alternator when turning is required. Hydraulics are always drawing power from the engine. The cruze rack was $1000 if I recall. The Toyota rack was roughly $1600
The energy wastage is a lot lower though. As with any type of hydraulic or pneumatic system, the energy waste can occur during the compression process of the fluids or gases through heat. And there is the consideration of leakage however slightly it maybe. And notice that there isn't any pressure vessel in the form of a can or tank to hold the pressurised fluids, you can assume with confidence that any fluid that has been pressurised but happened to be outside the confine of the looped system consists of the cylinders, hose and pipe to the piston is simply "dumped" back to the part that only serve to hold and feed the unpressurised fluid as well as to receive the excess fluid after pressurisation. You may also assume with confidence that this repeated dumping by design of fluids back to the reservior represent energy losses at levell that is much higher than anything negligible. The the extra length of contacting surface between one extra pulley and belt definitely adds friction and hence energy loss compared to the electric steering assist system which does away with this said pulley.
so the purpose of hex bolt under the pinion casing is to apply pressure on the rack some one had told me that it's there for the adjustment of the steering.is that right.
Another great vide from you! Only one thing that did not make sense to me. In the end (at 8:20) you explain on how some racks with variable steering, the pitch between the teeth are different from the middle and out to either side (to make steering quicker towards full turn?) Does the pinion also have different pitch, and are sliding up-down to adjust to the variation in pitched gear/cogs/teeths on the rack?
So the electric motor that responsible for assisting has to be mounted on the rack or close to it or it might be mounted inside the car behind the steering wheel casing?
Looks like that steering unit was in pretty good shape. I appreciate you sacrificing it for the video but isn’t that an expensive piece to destroy? Just curious
Is the Cruze steering rack able to move if the DC motor gets locked or something that prevents motor from spinning happens?! I saw some sort of planetary gear sets for coupling a electric motor to steering shaft which keep the main shaft still functioning with a siezed motor.
Nice vid like it, super interesting, i have a problem with my cruze, (service power steering ) Electric , 2013 cruze Is it the electric motor cause at first steers well but then the wheel turns solid, hard and cant turn. Is it 1. Add lubrication into rack 2. Change the motor and have it reprogrammed 3. Replace for a new one?
I simply can't understand how the mechanism at 3:24 would allow the rack to move freely WITHOUT the electrical assistance from the motor. Shouldn't the recirculating ball bearing block the movement from the rack?
hello sir.....can really over tightening of inner tie rod can cause damage to rack-and-pinion.....? or wheel/vehicle side-to-side jerking motion while driving...?
@@speedkar99 so nice of you sir .....that really make sense........by the way.....massage your body with mustard oil for any pain......i definitely need alignment.....i will get back to you with feedback...soon...thank you respected sir...
Thanks for the video. Just want to know, was there a plastic or brass bushing in that Toyota rack? I have a RAV4 electric steering rack with alot of side play in the rack cuasing major wheel wobble and knocking at soeed. I can't find a replacement bushing for it on the internet. Starting to wonder if Toyota ( rack made by nsk) just use the aluminium housing itself as the bushing (ie not rebuildable - throwaway).
speedkar99 yeah I know Toyota only sell the complete rack! Not even the Inner tie rods. But companies are selling these racks rebuilt. So must be parts available somewhere?
speedkar99 Yep looks like there is a grey nylon bushing at each end. Looks pretty specific for fitting in the housing. Can't believe nothing on the internet for this series of RAV4, litrally a $1 part. Will just have to buy a rebuild rack due to time constraints. Shame on Toyota for pulling these tactics. Thanks for video showing how to take apart
Thank you very much for that video! I wanted to ask you, on an electric rack like what is on the c7 Corvette, what is that very little mushy part as the steering wheel is turned from center? I mean slight. Like a few millimeters. Is there a spring in the steering sensor that allows slight movement before the rack is assisted by the motor? Or is the top shaft (the part where the sensor is) one solid piece that connects the steering shaft to the rack?
Electric racks don't have a torsion bar like hydraulic ones. The on center looseness is how it's geared, in addition to your tire and suspension setup. It's made like that so you don't accidentally sneeze and change lanes lol
@@speedkar99 so is the midshaft one piece on an electric rack? I know the midshaft or input shaft is actually 2 pieces in a hydraulic one in order for the valves to actuate.
hey man how to adjust steering stiffness on a 2005 chrysler 300 steering rack it's too sensitive too soft no play I checked it tie rod and ball joint is there a srew or bolt to adjust how hard or soft id the steering on a steering rack.
+Hallphamazing305 I don't think there's an adjustment for steering feedback, you'd have to change The restrictor valve in the hydraulic power steering circuit.
Cool video, man. I've got a quick question about my car's EPS. I have a 14 Accord 2.4 and the EPS has a resistance issue. Turning left there's almost no resistance (think Lexus) and turning right there's quite a bit of resistance. For example, when I make a 90 degree turn to the left the steering slowly goes halfway back to center but when I make a 90 degree right turn it abruptly goes fully back to center. This problem surfaced right after a chain tire store performed an alignment. That shop claimed they didn't do anything to the car that would cause this issue and even the shop forman at my local Honda store says he doesn't know what it could be. Honda checked the alignment and said it's spot on, so it's not that. Any ideas? Thanks!
@@speedkar99 Does Honda electric steering rack also have a little belt like that American cars?I have a 10 years old acura tsx with electric power steering,Iam worried what if that breaks like a timing belt, that is a sure accident waiting to happen no steering.
"There's a couple bolts here I'm gonna take off." GraaZZZZZZZZzzzzzzzz!!!! lol.

The the extra length of contacting surface between one extra pulley and belt definitely adds friction and hence energy loss compared to the electric steering assist system which does away with this said pulley.
great explainations. thumbed up
+diulaylomochohai thanks for the feedback!
Was the grinding necessary?
so the purpose of hex bolt under the pinion casing is to apply pressure on the rack some one had told me that it's there for the adjustment of the steering.is that right.
+cobra R yes it applies pressure to keep it tight and the gears engaged smoothly.
wow videos are amazing,from where you learned all electronics and mechanical stuff
+ajay javalkar thanks I'm glad you enjoy my videos. I learn my trial and error in my backyard.
+ajay javalkar Thanks, I learn by trial and error
So in “Part 2” are you going to show us how to re-assemble them?
"A dab of JB weld and a bit of red threadlocker. Done"
@@VortechBand It ain’t fixed until you wrap bailing wire around it. I use JB Weld for holes in my tooth. Its the small print!
Another great vide from you! Only one thing that did not make sense to me. In the end (at 8:20) you explain on how some racks with variable steering, the pitch between the teeth are different from the middle and out to either side (to make steering quicker towards full turn?)
Does the pinion also have different pitch, and are sliding up-down to adjust to the variation in pitched gear/cogs/teeths on the rack?
Another awesome educational video! Thanks!
Thank you
Wonderful demonstration. Perfect video.
+Sarath natakam glad you enjoyed it thanks
Thanks for good information 👌
Awesome
Sooo does the steering rack prevent/stop the wheels from turning too far left or right?? Wish you would have shown this in the video.
Awesome Video. Thanks.
+Auto Shack Thanks glad you liked it
Great video.
+ecordy thanks!
nice thanku for uploading this video
You are welcome. Glad it helped
☺
So when the computer or motor or toothed belt on that chevy decide to call it a quit on a twisty road, will the steering lock up?
Not lock...it won't have power assist
@@speedkar99 But since it is a worm thread arrangement, can the rack turn the pulley?
Dileesh VV i don’t understand what you mean, but loss of assist means you can still move the rack with the steering wheel.
Watling for the rebuild video on those
Haha rebuild it with a grinder
Excellent content great effects
What is the purpose of the pressure plate is it to stop play and knock clunk?
Yes it controls play and tension on the pinion.
So the electric motor that responsible for assisting has to be mounted on the rack or close to it or it might be mounted inside the car behind the steering wheel casing?
It's mounted behind the steering wheel on the column
Looks like that steering unit was in pretty good shape. I appreciate you sacrificing it for the video but isn’t that an expensive piece to destroy? Just curious
It was a brand new rack too but for science ...why not
lol.. hes obviously pulling them off of junkyard .. "but for science" .. haha..
Is the Cruze steering rack able to move if the DC motor gets locked or something that prevents motor from spinning happens?! I saw some sort of planetary gear sets for coupling a electric motor to steering shaft which keep the main shaft still functioning with a siezed motor.
Nice vid like it, super interesting, i have a problem with my cruze, (service power steering ) Electric , 2013 cruze
Is it the electric motor cause at first steers well but then the wheel turns solid, hard and cant turn. Is it
1. Add lubrication into rack
2. Change the motor and have it reprogrammed
3. Replace for a new one?
I simply can't understand how the mechanism at 3:24 would allow the rack to move freely WITHOUT the electrical assistance from the motor. Shouldn't the recirculating ball bearing block the movement from the rack?
Hmm that kinda makes sense...
@@speedkar99 You could move it at 1:51 with some ease - so I know it works - but I can't see how this was mechanically possible!
hello sir.....can really over tightening of inner tie rod can cause damage to rack-and-pinion.....? or wheel/vehicle side-to-side jerking motion while driving...?
Not really. The rack is pretty strong. You'd probably strip threads before doing any kind of damage
@@speedkar99 so nice of you sir .....that really make sense........by the way.....massage your body with mustard oil for any pain......i definitely need alignment.....i will get back to you with feedback...soon...thank you respected sir...
Thanks for the video. Just want to know, was there a plastic or brass bushing in that Toyota rack? I have a RAV4 electric steering rack with alot of side play in the rack cuasing major wheel wobble and knocking at soeed. I can't find a replacement bushing for it on the internet. Starting to wonder if Toyota ( rack made by nsk) just use the aluminium housing itself as the bushing (ie not rebuildable - throwaway).
+CD I don't think it's rebuild able. Look up Toyota parts catalogs online.
speedkar99 yeah I know Toyota only sell the complete rack! Not even the Inner tie rods. But companies are selling these racks rebuilt. So must be parts available somewhere?
+CD innner rack rods mevotech
Bushing you might have to measure and custom fit. Or fill with poly
speedkar99 Yep looks like there is a grey nylon bushing at each end. Looks pretty specific for fitting in the housing. Can't believe nothing on the internet for this series of RAV4, litrally a $1 part. Will just have to buy a rebuild rack due to time constraints. Shame on Toyota for pulling these tactics.
Thanks for video showing how to take apart
Is it possible to reduce the play of the electric rack from the inputschaft on the rod with that presure plate? And how do you do it thnx
Not exactly the okay, just the looseness, it will wear faster.
Thank you very much for that video! I wanted to ask you, on an electric rack like what is on the c7 Corvette, what is that very little mushy part as the steering wheel is turned from center? I mean slight. Like a few millimeters. Is there a spring in the steering sensor that allows slight movement before the rack is assisted by the motor? Or is the top shaft (the part where the sensor is) one solid piece that connects the steering shaft to the rack?
Electric racks don't have a torsion bar like hydraulic ones. The on center looseness is how it's geared, in addition to your tire and suspension setup. It's made like that so you don't accidentally sneeze and change lanes lol
@@speedkar99 so is the midshaft one piece on an electric rack? I know the midshaft or input shaft is actually 2 pieces in a hydraulic one in order for the valves to actuate.
Hi
Do you remember the mass of rack in 2nd rack assembly?
hey man how to adjust steering stiffness on a 2005 chrysler 300 steering rack it's too sensitive too soft no play I checked it tie rod and ball joint is there a srew or bolt to adjust how hard or soft id the steering on a steering rack.
+Hallphamazing305 I don't think there's an adjustment for steering feedback, you'd have to change The restrictor valve in the hydraulic power steering circuit.
Cool video, man. I've got a quick question about my car's EPS. I have a 14 Accord 2.4 and the EPS has a resistance issue. Turning left there's almost no resistance (think Lexus) and turning right there's quite a bit of resistance. For example, when I make a 90 degree turn to the left the steering slowly goes halfway back to center but when I make a 90 degree right turn it abruptly goes fully back to center. This problem surfaced right after a chain tire store performed an alignment. That shop claimed they didn't do anything to the car that would cause this issue and even the shop forman at my local Honda store says he doesn't know what it could be. Honda checked the alignment and said it's spot on, so it's not that. Any ideas? Thanks!
They might have messed with the caster setting which is responsible for returning the wheel to center
speedkar99 awesome, I’ll check into it. Thanks
very good movie
+Junmo Koo glad you enjoyed my film
Fantastic video! You really butchered those racks :) Were they faulty?
+Koffi Banan yea well the grinder is the only way to open those proprietary bolts. No they weren't faulty, this is for demonstration
Waw, I really appreciate the effort. Hope you didn't have to pay for them, I don't recall them being cheap.
+Koffi Banan yea $1000 for the Chevy and $1600 for Toyota.
even tho they look like quality made this is a heavy overprice. and they even use brushed motor
@@speedkar99 Does Honda electric steering rack also have a little belt like that American cars?I have a 10 years old acura tsx with electric power steering,Iam worried what if that breaks like a timing belt, that is a sure accident waiting to happen no steering.
Thanks and great work ?
Your welcome
