Hmmm...I need to do this as well. I’ve noticed the same on mine.

Should the bladders always hold some air/pressure in them or is it normal to deflate after sitting for a while?

if everything is in good shape they should hold air for quite a while, mine has sat for days and still were nice firm, that's how I found out I had a leak they would be deflated in the morning or after sitting for several hours, plus I could feel it wasn't right while driving

You guys got me worried about burning up my air pump, so I ordered the Arnott AS2708's from RockAuto. Should be here by Friday

Remember to double check the ABS cable connection above the frame near the top bolt. You barely bump that thing and you'll get a Stabilitrack and Traction Control error.

The whole emblem looks like garbage. It needs a whole sticker or new emblem. Looks like the previous owner was gnawing on it
They sell those too. Mine was trashed so I bought both since you can’t buy the center piece with a black bow tie. I installed the sticker then installed the badge. It’s easy you just have to be careful and I used RTV on the badge so it wouldn’t come off.

They definitely don’t hold air overnight. Looks like I need to break out the soapy water.

Put in new plugs and wires today. The #8 cylinder was not as bad as Youtube implied. It was a tight fit but took only marginally longer than the others. I think the whole job took ~90 min. The truck seems to pull stronger now, but objectively, picked up almost an extra 1 mpg average over a 20 mi drive. Not sure if the plugs/wires are factory or were replaced at some point (they came out without issue and wires seemed in decent shape).

Been there. Done that. Still figuring out how to fix it.
