What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[13BurbanKid]

Tried to change all four oxygen sensors because another code was thrown. 3 out of 4 came out easily and went back together beautifully. But the left upstream sensor is combative. I'm reasonably sure the threads are ****** and I will have to weld in a new bung. **** my life.

Installed the 2” rear drop. Now to get tires on the 20s so i can ditch the ol stock wheels haha

Anybody in here need/want some esky roof rack end caps? I’ve got 4 that are the maroon of my 07 Burb I’m looking to sell. Paint is in great shape or paint them to match your rig. Looking to get $75 + shipping for the four. Figured I’d ask y’all before making a separate thread with pics and before listing on local marketplace

I would see if I could find a tap and see if you can clean up the threads when you get it out.

We still love you anyways, Tony!

I can try the torch technique but I am sure the threads are still not good. It feels like breaks loose and then jams up tight and won't go any further.
