Hey, thank you for sharing bro...i think the only precise video for sensors changing. Very grateful 🙏🏽 One question , do i have not to put the LC all 4 wheels up on Jacks before removing the old ones? I'm changing all 3 sensors today on my J100...wish me luck:) 😊

thank you for the kind words! I did the rear sensor without jacking up the truck at all - I just put the AHC in "H" and slid under (you should always put jackstands under the axle or frame just in case, but i did not get the tires off the ground. so the jackstands were there as a failsafe). as long as you turn the truck off before you get underneath, there shouldn't be any reason why the suspension would lower itself while you're under there. the rear sensor is super easy! I haven't had to do the fronts, but they shouldn't be too bad. you got this!!

Thank you dear again. Yes it was super easy. Changed first all 3 sensors and the fault was the rare sensor which caused all the bumping and malfunctioning. The long story with the AHC malfunctioning, which took me almost a month till yesterday, is over. Now it works properly. You know, i was quite sure that it has to do with accumulators and diagnosed it with OBD and got low pressure in the system. So i inspected all 4 accumulator globes, were good and pencil test done, were all pure and fitted them back. Then the most difficult journey started with the accumulator pump...i can't tell you all $ and energy it costed me to get new part from US to Ethiopia, big theater with border security in DC airport, they took it away on passenger flight as it has compressed gas inside and payed 1000usd Dangerous good Air cargo shipment...tax in Addis Ababa 500 usd , buying price with the sensors from toyota dealer in usa payed 2500 usd ...😢 Then tried to take out the old pump, that is almost IMPOSSIBLE! ...Two Bolts are under chassis where you can't access them , killing. .. that was all done and the oil line bolt rusted and damaged to gett it off, used all available Special sprays ( rust off ) didn't help and i cutted it -off and weld it back with new bolt. New pump fitted back and big surprise,... didn't work still, AHC failed to lift the front side and rare side lifted Tooooo high as the begging. Tried all to check But finally...finally where i almost lost the hope where to get the couse , by chance I saw your video and thought let me simply change all sensors, THAT WAS IT ! YES It was the RARE Sensor it coused the problem. Many fellow people posted only accumulators changing as solution, and I think I'm the only one who changed the Height Control Accumulator pump , which i think is built for lifetime. Wasn't necessary at all in my case to change it. Thank you , i almost told you here all my journey with AHC researching, where i fill now I'm MASTER of it 😊 Happy to share my experience and i will continue taking care of my bloved Iron-Model j100. ❤....and enjoying it till we both get old 😊. Cheers!...

@@wubeyilak11 that is amazing!!! sorry to hear about all the trouble with the accumulator piston though... I'm so glad to hear I was able to help!

I really needed this! Thank u

[@NKPGarage]

did the height control change with the new sensor in place?

[@geriatricpearl]

it brought it back to spec! before I replaced the sensor, the rear end of my truck would raise and lower itself over and over as soon as I put it in park. It got so bad that any time I would park, I would turn AHC off. replacing the sensor fixed that problem!

[@BatmanBoss]

Is there a sensor on each side?

[@geriatricpearl]

nope! only one sensor for the entire rear.

i changed it because whenever i was in park, the truck would lower and raise itself over and over again unless I turned off AHC. replacing the sensor fixed the issue.
