It's not fixed. They will pump up and feel okay but it doesn't last. This threat is proof that this is a common problem. Next I will check the rear caliper slide pins which I almost did when I had the wheels off but didn't ...

[X] 3UR Oil filter wrench (09228-06501?) - just used one from O'Reilly's
[X] Oil drain plug gasket (90430-12031)

Used the Cerakote kit. Unfortunately, some of the issue is on the inside of the lens. But the outside is done and it did improve them.

Let's play how many of these does my truck have?

From the FSM. It describes a 2 stage cat efficiency check procedure. The first step is driving and the second step is idle. It won't do the idle test until the driving test meets parameters. There are two PIDs in the data stream that let you know what is happening.

I'll throw this in here. So one of the codes was C1340 Center Differential Lock Circuit. I think it makes sense to swap back to the original diff actuator before chasing this. It's not clear what the symptom even is because everything seems to work.

No. I need to.

Nice and annoying to get in the air. Had to jack the front left and right up separately and held it under the main crossmember. At the rear I just jacked up by the diff and supported via axle tubes. I am really over jacking up stuff and I barely got the ...

Ran out of time/energy so I decided to at least check the level of the front diff fluid. Good thing I did. It was down 0.8 qts. Yikes. I don't think it leaked out - I think he never added fluid after doing the front actuator.

I decided to check the transfer case level and rear diff level. Fluid ...

Added spring clips. Fitment was not great.
