2023 Cascadia popping noise only when it rains!

Anyone try greasing the front end? I would grease the king pins with the wheels on and off the ground to be sure. Check that no bolts or anything are loose, u-bolts, spring hangers, steering box, mounts.

 

Same thing on mine & several others I know of. 2021’s. Gave up and said f it after 3 trips to shop & countless times greasing different components. Over 200k now & still the same.

 

I suggested we just don’t work in the rain. Powers at be didn’t agree.

 

These are the usual culprits and are the first things that need answers to these questions by OP.

 

Does everyone with the problem have air bags? This is a great mystery that needs to be solved. Lol.

 

Apparently, we have airbags & that’s the conclusion we came to. OP drive’s to much. 336k on a 23model, when did you find time to grease it ?

 

I would also check my hood rests and brackets, as well as cab mount bushings. On occasion the inverted funnel shaped rests, could cause some odd noises and they are a common wear point.

 

That’s all rubber/composite bs on these trucks. Not the brackets, but other components. It’s got to be inside air ride. I’ll cut mine open whenever it goes to shop for a while.
