Just for the record. Other than the time I just mentioned I have never used the 4wd on pavement. Don't know why it failed but that wasn't the reason. The only time I have really stressed it is towing my 5th wheel in 4wd. I pull it down the Apache Trail in AZ which was a dirt road but has...
Thanks. Just freaking out slightly since it only has 40k miles on it and I hardly ever use 4wd. Tech thinks the failed carrier caused the T-case failure. Hopefully it's fixed.
I just got my truck back after 6 weeks at the dealer. I took it in because when it was in 4wd the front end sounded like it was going to self-destruct. The tech replaced the T-Case and front driveshaft. He then test drove it and found that some noise was still present. Ended up swapping out...
The sensors are not calibrated at the sensor supplier. They are very simple potentiometers with wiper arms. They are so cheap I doubt they even test them. Hopefully the system is calibrated during the truck assembly process to set normal ride height but I doubt it.
Just to be clear. I can adjust the rods so that both bags are at minimum pressure (empty) and ran like that for about a year. Recently I adjusted them to add some air so that the main springs don't bang into the overloads when I hit large bumps. So both bags are currently running about the...
I have adjustable sensor rods. They are adjusted to keep the bags with an equal amount of air for normal ride height but that doesn't solve the bed lowering issue. The system should empty both bags but it doesn't.
I just tried bed lowering mode and transport mode without a load. The passenger side feels like it is close to empty but the drivers side still has air and is pretty firm. I think it goes back to the original problem that the system thinks the drivers side is at minimum pressure but it isn't...
I agree but it doesn't. The bags don't empty. Also, when the bags are adjusted to be empty my overloads do not touch. There is about 1/4 to 1/2" gap. Since my truck is one of the ones that had air in the drivers side but not in the passenger side when it came from the factory I assume that...
Bed lowering mode doesn't change the rear height of my truck unless there is a load. The display says it works and I hear noises coming from the system but the amount of air in the bags doesn't seem to change and the overloads are not touching the main springs. With a load it drops the rear...
I just measured my rear shocks (shocks connected) with the wheels off the ground and the truck supported at the hitch. Center of eyelet to center was about 27". I remeasured the stock shock that I took off and it was 25.75" extended. So it looks like the stock shock would limit the spring...
After re-reading some threads it doesn't sound like there is a definitive answer on whether the gauge/message is functional on trucks built without the sensor. Basically just a lot of opinions and observations. Some say the gauge works and they get a display message when a regen is occurring...
I have never seen an indication of a regen, gauge or otherwise. I don't pay that much attention to engine noise or MPG but I have never seen a display message either. I typically don't DD my truck. It sits in the garage and we take it to our lake hangout every other weekend. So about 3hrs...
My '22 is missing the sensor and I have never seen the gauge move off zero. I thought I read in one of these threads that without the sensor the gauge is not functional. Is that true?
I wouldn't order anything until you measure your truck. Thuren told me the factory air trucks vary in rear height from truck to truck. I think that's why it's hard to find parts that say they will work although many of the parts will work. I used the Carly 1" block for the rear per CJC...
I didn't touch the sensors. The distance between the leaf spring and the sensor doesn't change. I have never used ALT. Maybe next time I tow my 5th wheel I'll try it. I tow my boat regularly but I don't think the bags fill up much so ALT probably doesn't work.
Finally got around to installing some new front springs and rear spacers. I ordered from CJC but they just drop shipped the springs from Thuren.
