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.

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.

Actually, it's not fully stock. It turns out it has a 3" lift on the front and something less (for "leveling") on the rear (maybe 2"?). It's funny that I didn't notice until we said "what is that weird thing on top of the front coil over?" It's not objectionably tall though if I could snap my ...

I might recall that happening when I ordered pulleys for my E63. You can just call the parts counter to confirm but I didn't have any fitment issues.

As part of the registration process they made me look up the GVWR. It's 7100 lb which seems like a lot for a half ton.
