Got that, but was asking @the_tool_man how many miles was on his truck when Blackbear said they were going bad.

They tend to go longer than what they are rated for, depends on how you drive mostly I think, I only did mine as preventative maintenance I have had a bit of trouble with 02 sensors in the past probably because I didn't change them all at the same time like they recommend and my exhaust had been welded on multiple times because of the cat's going bad on me left & right.

It had 98k when tuned, 122k now. He didn't say they were bad, per se. But he said it would be a good idea to replace them soon.

Lucky how? That I got 122k out of them, or that I didn't lose any fingers replacing them?
That there was threads left over to screw the new sensors into, I’m guessing.

Yeah. That they came out without a headache or hassle.

Hi. Welcome to TYF where we have threads with 19 pages about unscrewing one effin' sensor.
...Ok, so it's just one thread.

And in the end there wasn’t any threads left...
Funny, I just went through all my maintenance records for the Yukon and couldn’t find I ever bought new O2 sensors and no service invoices showing even one was replaced.
So I decided I would order 4 Delco OEM sensors from RA and replace them all. When I went on their site, they label both part numbers they sell for my model year as Downstream.
Did you run into that when you got yours? I suspect Denso makes them for Delco, might just get those.
