Cascadia daycab airbag slight lean towards rear
Posted by heavyramp@reddit | Truckers | View on Reddit | 11 comments
The shocks look vetical, but the airbags lean slightly towards the rear. The ground is flat, and I notice no changes in lean at different locations. Is this of a concern? It's a 2025 model with 110,000 miles.
How often do airbags get replaced? I don't hear any pops in the suspension when making turns or going over driveways. I've read that the airbags near the drives have a industry wide issue with leaning airbags, but I wonder if it's also a thing with cabs. I've noticed 1-2 other trucks with the same airbag lean in the cab. But that's out of 40 or so trucks. Most are as vertical as the shocks next to them.

One or multiple cab mounts is bent. Eventually it will wear out the other mounts, the air bags, and the shocks.

The most recent word from the leasing company is that Freightliner is aware of it, but everything is in spec, and nothing is going to be done. The ride quality is fine as of now. My only concern is that is could be leaning, but apparently airbags that small for the cab don't play a big role in that function when driving down the highway. Now when I'm at stops and deliveries, I'm always checking other cascadia's cab airbags.

I own 45 Western Stars. I don't have any problems with cab or rear suspension

Someday I will haul milk. One of the few sectors in this industry where I've noticed the equipment is taken care of.

It's hard work but good money We wash the truck one day and trailer the next day. If we can at the dairy. If not we have a wash bay at the shop. Also have 7 mechanics that work around the clock

Did you get it fixed?

My guess is that it'll never get fixed, and will be considered an aesthetics issue. Apparently the rear airbags by the drives is a freighliner wide problem.

In the second pic, the right airbag looks like it is leaning more. Maybe the cab was involved in a incident that shifted the cab sometime in the past.

Wouldn't doubt it. I can check the vin number later on.
When looking at the truck from the drives pov, the cab looks level.

Play around with your leveling valve for the cab bags. You can always slightly over inflate them to see if you need to make a custom mounting hole for the actuator.
These are the type of modifications you just do yourself, don't try to ask for permission you'll never get it, if a shop mechanic does mention it; better to ask for forgiveness.

The ride quality is fine in regards to stiffness or overly bounciness. Better than others. But can the bags make the truck seem like it's leaning towards one side? It's hard to tell due to the crown of the road.
Penske leased trucks aren't exactly taken care of like how we all want them to, so I see your philosophy on it's better to ask forgiveness. I have no idea on where or how to mess with the valve, however.
