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

[Charlie207]

Installed some yellow LED fog light bulbs, so I can be fast like a Group B rally driver.

They were very easy to install, and I'm not sure why all the videos I saw required people removing fender liners.

You lay on your back staring up at the bottom of the radiator, and can basically look directly at the back of the fog light housings. Reach in and pinch the bulb to remove. Done.

Swapped out the old chrome LTZ five spokes for a set of Silverado wheels. The Chrome was starting to flake and slow leak around the bead. Found a guy on marketplace that swapped his for black rims and just wanted them out of his garage. Got lucky with that find. Glad I pulled the trigger.

Looks great.

I have yellow ones too. They did increase my speed!

Installed a new GM charcoal canister in the 2007 (did the 2012 last year) as a preventative measure. As far as I could tell the one I removed was the original so I was on borrowed time. It's such an easy job and the consequences of it releasing its pellets such a PITA, I consider changing it just routine maintenance.

Didja also put a handbrake lever for each rear wheel?

Where is it located?

Just ahead of the rear diff, mounted to the driveshaft tunnel. Gotta drop the spare to get at it, but swapping it out from there is a 10 minute job.

I also bought a new vent valve intending to replace that while I was back there, but the one I ordered is the wrong part. Amazon parts engine strikes again!

I did my vent valve but I still want to get that canister done.

I’m wondering if I ought to justdoit on thecopcar as a preemptive thing.

Split hydraulic system: Straight back locks both rear wheels, w/L-R movement for independent control. Straight forward is line-lock for big smokey burnouts.

Cutting brake, nice touch!

Ya'll notice any HP gains - I read on the interwebs that yellow provided about 5 extra and lower drag.

No HP gain, only 1000 torques.

 

[Meccanoble]

Replaced both upstream sensors and cleaned throttle body @ 247k miles. The driver side was crazy difficult to get to and I had to remove tire and plastic wheel protector area just to get to this sensor.

Then, worth every penny-everyone knows its the torque that matters! lol
