Appreciate you watching and your support on this channel. Hopefully more vids on here come to help or Atleast break down the knowledge on repairs needed in the future. Stay safe out there.

Appreciate your positive feedback. Hopefully more things come in handy on this channel. Try it out yourself and save that money right

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.

Thanks for coming aboard. I’d have to look that one up. I imagine it will be the same. But I can’t say that for certain just yet.

When u say adjusting air bags do you mean when installing them or when I’m adjusting ride height. If u mean ride height I just set it to a certain measurement instead of looking at the bag fullness.

For the FTL cascadia I believe 2014 and above it’s 2 3/8

Yes sir. Take the weight off first.

I don’t get many of the front air ride units at my location. But next one I come across il make sure to run the leveling procedure on it.

@@bustedknucklebydieseldr3228 thank you.

Great question and thanks for reaching out. You should be able to loosen the actual valve and raise or lower it to what you need than just tighten the bolts. This came be done without removing the linkage to make it easier. Hope that helps.

If you can fit that snuff can it’ll be perfect. The measurement needed is 2 3/8 so as close as you can get up that. Close is good enough.

@@bustedknucklebydieseldr3228 Got it. Thanks for the reply!

Thanks for reaching out. What are the exact issues your feeling and what have you had done.

Thanks for watching and reaching out. Yes the fl model can be adjusted the same way. The cab air bags does have an adjustment and I’m pretty sure I have a vid on that one as well.

There is an acceptable range and 3/8 to 9-16 if so close I wouldnt worry to much about the difference. As long as your close your good to go.

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.

I’m pretty sure there diff measurements. I’d have to look those up since I don’t get those very often.

Not sure what you mean. Which high pressure line and how would you DIY it.

The ride height is a bit diff on the columbias. I’d have to look up the specs for that one.

Good question. If it were sitting at an angle than it should either be filling or emptying the suspension. When level it will be sitting pretty close to straight across.

Just go slow and in small increments would be my best advise. It can be a real pain. But remember your only taking the measurements from the drive axle not the 3rd axle

@@bustedknucklebydieseldr3228 10/4 so I’m possibly rushing it

@@bennyhall2790 maybe or the 2nd axle is fine and the 3rd axle your just worried about.

Hi, it sounds like you may have something else going on with how the valve was adjusted. I'd like to know if you eventually found out the issue?

Good question, whether new or old tires they would still be the same reading. The frame should be siting at tire height for reference. The valves goal is to maintain that specific height.

Busted knuckle by diesel dr I just measured the height rear axle is 3 inches front of is 4 inches. How do you explain that? Which axle should I take as a reference

@@Vertikala-pc5ig your axles will not be the same measurement. I’m pretty sure I say I’m the video to only take your measurements from the #2 axle (drive axle) on the truck.

They will not be the same height. Take the reading from the front axle.

Also seen it's double pinned the first pin before you start lowering it does it go on the top hole?

I am soo fucked

Great question, you set it up when unloaded. When the truck is loaded there to many factors in place that would never get an accurate measurement.

Damn, that’s a good question. Let me get the last 6 of your vin and get back to you. I’d have to look that up. Would hate to give you an unhonest answer.

Definitely will.

Thanks for reaching out man. Without looking at it or listening to it,,it would be so difficult to diagnose. If it sounds like and engine miss than that would be a great place to dive in. Could be weak cylinder or bad injector. Really would need to have it sent into a reputable shop.

Thanks for the reply man, yeah I've had it in the shop and they replaces the wiring harnesses and said the injectors was fine. I think I may try replacing the boost sensor next. But I don't have a check engine light or any codes coming up

@@BeardnSon figure out your issue? I've had this leveling problem for 2 years now with those exact symptoms and spend thousands of dollars and still no diagnosis. Starting to attack braking system.

Great question, unless you have some crazy size tire it will be the same measurements

Thanks for watching and reaching out. You have a unique case and it could be cause by a few different issues. Your frame could be tweaked/// your springs might be replaced on one side and not the other///misaligned air bags on there bases// unequal air flow to one side. Once you narrow it down it will be an easy fix. Hope that helps you out.

@@bustedknucklebydieseldr3228 i guess ill replace the leveling valve first, thanks for the reply

Which I could of shown the backside of the valve. There is a hole on the lever arm and the valve itself. The pin goes through both of them to be aligned. I’m glad you asked. Hope others read this.

Good question , yes the rear will normally be higher than the front axle. Could change slightly depending on age and weight. But as long as the front is good and you only have one suspension valve than no worries.

@@bustedknucklebydieseldr3228 thank you .

Title is adjusting. As for replacement, it’s just removing and installing the air lines and same adjustment.

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.

@@bustedknucklebydieseldr3228 My plane Jane 15' Cascadia has no splitter or locks. Sometimes I have to bobtail of the trailer and drive around for 5 minutes then rebook and cross my fingers, Sometimes the forklift drivers give me a nudge.

@@ThatOneGuy-hp2pb well if you plan on keeping it than I recommend adding a locker

@@bustedknucklebydieseldr3228 okay, thanks!

​​@@ThatOneGuy-hp2pb did you fixed you problem or found the reason? I have the same issue currently

Pretty close. A cascadia but close enough right.

24s. Is that it. You know it doesn’t look right unless it’s 32s or bigger.

@@bustedknucklebydieseldr3228 😑

Good question. 3 inches is fine. Tell her that’s normal. I mean how much more does she really need. As far as the suspension height, 3 is fine. But to high or to lo low and you mess the the driveline angle which will cause extra vibrations. You need that perfect relation between sus bag fullness and driveline pinion angle. Hope that helps clear some things up.

@@bustedknucklebydieseldr3228 ha ha I’ll play with it up/down see what happens. Well we know what will happen if I play with it too much. Seriously that vibration drives me nuts.

@bustedknucklebydieseldr3228 hahahahaaa, that first part of the answer tells me, you have a bright future as stand-up comedian 👏👏👏👏👍

I can’t remember as this was many many moons ago. But p3 and p4 platform use the same height specs. So for a 2017 you should be good to go with that one. Hope you get it dialed in.

@@bustedknucklebydieseldr3228 ma man thanks a lot for responding i dropped to 3x1,4 I yesterday I got a lit bit heavy load and still my rear drive axle shaking in about 66,67,68,69 Mile and as soon it’s get to 70,71,72,75 it’s just stop shaking or vibrating and today I got a 16k weitgh on my trailer and it’s drive so smooth after I stoped and measured with a loaded trailer i went under I check it out it’s was at 3 inch exact we’ll probably I’m thinking to set them up by 3x1,2 when I get heavy loads it’s any ways goes down to be on 3 Inch as you said probably goes smooth again what do you think abt all this info ? Thanks a lot ma man

You know brother the story I had with my radiator cracked and my truck got towed with a loaded trailer after that this problem pops out right afte exact 2 days when I drive bobtail I don’t feel anything even with a empty trailer as soon I got a lit bit heavy loads it’s start shaking vibrating on my rear drive axle and my passenger sit shaking also but I don’t feel any shaking on my steering

Thank you for reaching out I always appreciate hearing from you guys. Sorry to hear about your issue. I don’t have my own shop just yet but maybe when I build my channel that may just happen. Can you describe your losing control on your truck issue.

Hi I have I bad noise hearings and I have I vibrations on my front tire and the truck is moves lake a snake

Great question. Thanks for chiming in. Hope I addressed that in the video. Chock blocks down so the truck doesn’t move around to much and park brake released.

Appreciate the quick response.

So I did exactly this and it rode great until I got unloaded and it did not go back to same measurements. Any ideas?

@@CrodDc5 great question, if it fails to maintain the proper height I would be leaning towards a crappy height valve. As long as the linkage and arm are in good shape with no bends. Try it a second time and if it continues to fail than replace the heigh control valve.

Yeah this one is only like 2 months old and can't get it dialed in. As soon as I switch loads it rides roug. Almost feels like the rear drive axle is stiff.

Only check it on the d/s 2nd axle for most accurate measurement. If there is two suspension valves the procedure changes a little bit.

@@bustedknucklebydieseldr3228 thanks bro. Looking forward for more videos. 👍

I have a 99 freightliner century class and I tried that method and it's still riding rough and now my abs light keeps coming on. This ride is unbearable

@@klco74 thank you for reaching out. Always like hearing from my audience. 99 FTL will ride rough. They are known as freight shakers. Best thing to have done is replace shocks with nitrogen charged if you can find them and have all springs and bags inspected for any issues. There are so many components that will cause a rough ride like wheel bearings , out of balence tires, driveline, motor mounts, cab mounts. She would need the full inspection and being a 99 unfortunately it may be very $$ to get it all done. Hope that helps

On my 2021 Cascadia driver side is 2 3/8 and passenger side 2 1/4 Is this is ok Truck doesn't drive like it should

@@lakhbirhothi9223 those readings are pretty close and you shouldn’t notice bounce with that. If you do there’s another issue. If you don’t mind dealer rates I’m running the show at chandler freightliner in Az We can definitely check out your concerns. Just Gta be prepared for that door rate.

Hey bro one more question I adjusted value to the setting And then when I hook up to trailer it is 2" now. You think something is wrong with leveling valve

@@lakhbirhothi9223 the valve will do its best to keep that setting. But with the weight of the trailer it may not be able to. If it was way off I’d say replace it but it’s close so save your money for now.

Oh crap. Don’t tell my wife. She may want an upgrade.
