Mine's fine too, just hit 118k.

Where do they usually break at?

Usually the bolt on the body, not the one on the frame.

Yessir. Might be the cat itself though. You can swap the downstream sensors and see if the code follows. If it doesn’t then it’s the cat.


I would love to be able to swap out the sensors from side to side. Crappy thing is that was the one that was replaced last year.

I just tried that, they are in there. Trucks got 113,*** miles it stutters occasionally at slow speeds. I’ve been told it’s the AFM.

It’s due for the yearly inspection, gonna ask to see if the cats are needing replacement.

Added the front diff skid plate.

Used these washers between the plate and frame just because.

What's the reasoning behind the neoprene washers under the skid plate? I'd be worried that they would eventually deteriorate from the elements and cause the plate to rattle, or cause the bolts to loosen and leave the skid plate hanging down?

If the two steering wheel accents silver on any of those trucks intact and not worn out or scratched as well as the window switch plates. Let me know what you get. Mine are worn out on the wheel and both from window switch plates.

It’s just personal preference. I like the idea of having something between the plate & frame. I’m under there often enough doing regular maintenance to keep an eye on it. I did the same on my 2015 with no issues.

I have a brand new front passenger switch bezel in brushed metal if that’s one of the ones you need.
