DIY How To Replace Semi Truck Suspension Air Bag (Peterbilt)

[@eriksatterfield4755]

All these vids I looked for and couldn't find any that had a peterbilt or even a box truck with a 20 foot or longer box. This video is perfect. And I had the exact same problem the 2 15mm bolts won't come off I tried dosing it with wd and heat them with a torch and I got nothing. I'm just gonna snap them off like you did. Thanks for the video dude

Great job, I always use Antisiese

[@elliotkane4443]

Nice. I almost had a heart attacker when you pulled out that shifter to use on the air lines though. I'm sure you know this by now but you should always use a line wrench/flare nut spanner on compression fittings, they tend to crush or bend the pipe inside if you don't, they also round off a lot easier if you use an open-ender. High pressure fuel lines, brake lines and air lines on trucks, hydraulic fittings are usually too big and are a different type of fitting anyway, they should be okay. I'd also put a bit of nickel/copper anti-seize on those threads, may make for an easier job next time.

Thanks for the tips!

No problem using an adjustable wrench on those air lines, It works just fine if you have the space for it, only issue you'll ever run into is them being seized or too tight and it wanting to slip, In that case a regular wrench will do, a line wrench is pretty well unnecessary, And if you ever get towed 9/10 it'll be an adjustable wrench that takes apart and puts back together any air lines that need to be accessed, You will never have an issue with an airline because you used an adjustable wrench to remove or tighten a compression fitting.

Where did you get the fittings from?

[@johnsonberry6750]

What model peterbilt you have?

[@dflk2580]

Why only one our bag you should change all four

[@therealtrucker7564]

Maybe he did. Doesn’t need to show him changing all of them.
