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

[j91z28d1]

(Minor?) Neck issues myself, always cramped feeling.. trying to stretch it all the time. Makes a lot of cricking creaking noises.
So I feel you on flipping that headrest backwards in your car.

I say minor since it's just old age too and mostly used to it. nothing I'd get surgery to fix. Trampoline injury as a little kid. life time of arthritis, BMX crashes and bad posture catching up to me. being tall doesn't help much either lol.


some pics.. I'd say it's a touch better it not a huge difference. the original is much thicker. so it feels about like this adjustable one forward, and then back gives you a touch more room even thou the angle is about the same. Just less padding.

back


forward



glad I got it, but wish it a little more angled back. I wonder if I can modify it.

way too forward for my taste's, I was thinking it tilted back

Installed new upstream O2 sensors. It's easy with the correct socket - the tall one, not the short junk.

Ordered OEM GM from Rock Auto and got Denso manufactured units. Old ones were Made in USA-marked Densos, as well, but a different design. No clue how old they were.

At least it does look thinner. The stock one protrudes from the seatback plane, the adjustable one looks about flush, though still angled forward. (possibly more even)

yep.. while it's more pointy, all the way forward feels about like the fixed back. doesn't look like it thou.

be interesting to see what you think. i might pull it apart and see how the inside looks.

I soaked the threads in the People's Blaster for three days before today, and they popped loose with almost no effort.

A loooooong 7/8ths wrench can reach in there too, but might not give the best grip on the hex head of the sensor.
