Bouncy clunk rub clunk rub rub rub...... Looking for a thread on fixing a noisy cab latch / air suspension

[GeneralDisorder]

And yet another variable are the front cab mounts and pivots... Is your cab on square? Clamp a straight edge onto the frame and measure out to the rear cab edges. Depending on how the front was bolted together or impacts the chassis may have sustained, your cab may be askew IRT the frame causing your interferences at the rear. In building up my habitat frame I discovered my cab is twisted 1/2" to the drivers side at the rear...

Definitely a concern. My truck was hit in the drivers step and it bent the $hat out of the step and step curtain. And then in addition the floor above the lift ram was buckling from the bouncing of the cab from the AOP pulsations. Royal mess. Replaced the step and step curtain and both fenders (one cut from the accident missing a whole section and the both sun-damaged and severely warped. Once I got the latch bracket level, and centered it stopped shifting to the right at the back when engaging the latch - then I had to angle the latch to match the angle of the cab pin...... was all just a big angry wrestle fest. I used Nord-Locks on everything to prevent anything from shifting hopefully...... Replacing the cab bushings showed there was no significant shifting of the cab on the originals in my case. It's just a real nastly stack up of parts - the tire crane, the air lift spreader frame, and the latch bracket all bolt together and have to align within a tight window for the cab pin to hit the latch square and for the front of it to slip between the latch and the engine hoisting bracket.
