Great video man! This will definitely help many drivers. I have a question, I adjusted my second axle to 2 3/8 but i noticed that my third axle is at least one inch higher. Is that normal? If not how do i make all 4 air bags inflate equally? Thanks for the great videos.

[@bustedknucklebydieseldr3228]

Always appreciate that positive feedback. Can’t do it without support from viewers like yourself. As for your question that rear most axle will always be higher so the measurement will always be taken on the mid axle only. So if that’s what you measured than your golden. Celebrate with a beer.

[@CartersEnterprises-m2g]

Hello! I have a 2018 Freightliner Cascadia JSJY1055 and I have been watching to try to set my leveling valve. I’m noticing that you said that once you get to 2 3/8 to clock it down and tighten the screws. My measurements per freightliner is 2 5/8 but I believe your video is the same for my truck setup. When I lift my height control valve up if I’m too high my frame goes down…is that correct or should my frame go up when I lift the valve up? Not the linkage but the valve. Then when you say to clock it down, can you further explain what you’re saying? For some reason my setting seems to move and not stay where I’m setting it. I very much need your help with this. I’ve paid out $30k last year because no one was able to find my problem which was left rear motor mount. So because of that so much has been replaced, removed or tweaked trying to find the problem. Thank you in advance.

[@travishudson6178]

Not sure if you ever figured yours out but I got confused on the Clocking part as well, when it was on the bench would have been a good time to explain the clocking part. Also good point about the whole unit moving vs just the arm part. Explaining which one does what. I noticed the arm moving but did not hear any air going in or out except when it was way down so was already set at that point?

[@JagdeepSingh-wv1ry]

On my truck the link that connects the leveler valve and axle is too long. I had to bend it in order to lower down the height. Its much better than before the ride and the vibrations. But vibration is still there and is there any other way of lowering the height, since the link is already bent.

[@bustedknucklebydieseldr3228]

Thanks for reaching out. I would say the problem here is you have an 88. I’m sure that thing needs some major love but hats off to you for keeping it running. Suspension height will affect stability and bounce issues and ya id prob inspect that but Deff not stop there. I have a lot of other videos about vibrations. Everything suspension related should be checked. Including checking the balence of those tires. I know this doesn’t help much but keep it simple and check every suspension component first than move on to carrier bearing or driveline, than sus height, than tires. I know you’ll find your issue, or many more along the way. Stay safe and stay grinding out there.

Great question. Many people run into similar issues. I believe the main problem is design. Without all that weight on the backend traction will automatically go away just as regular pickups fishtail around most corners. Trucks need weight. There are feature that help such as. Load transfer and diff lock. Both do great in different ways. I’m sure your truck came with a diff lock to lock in traction so I’d utilize that. But some newer units have load transfer where air pressure in the air bags are used to reflect a heavy load to gain traction. Hope that clears things up and thanks for watching.
