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

[14Tahoe]

Is this what you used? https://www.valvolineglobal.com/en/extended-protection-flexfill-full-synthetic-gear-oil-sae-75w-90/

That’s it! Autozone had it for $18/quart if you buy 2 or more. I found 6 quarts was more than enough to complete the job for both with a little extra for cushion.

Great, thanks!

backed up into the driveway to park after running my daily errands and...... service TPMS yay, they had a good run 13 years

@LSCALADE nice work! They look great.

I want details!

What bi-led projectors did you use?
What is your power source for the bi-LEDs? Or more specifically did you re-use the OEM HID ballasts for power or did you re-wire the headlights to not have to use the OEM HID ballasts?

Got any nighttime pics from the drivers seat? I’d like to see more on the width and throw of the light pattern.

Traded a set of Magnaflow Mufflers for this brush guard. We have no idea what its off of but i think i can make it work for Betty. Really just gonna use it for running Offroad lights. I do alot of nighttime driving in deer country so more light is welcomed.
Thinking of having the top bar just above the GMC. Makes routing wiring easier.
Gonna put some 4-5 inch Round LEDS on the bottom bar and perhaps some amber markers on the top..still undecided.

oddly enough the service tpms message went away and has not returned, I keep checking the tpms readings 33,33,33,38

Well the one reading 38 left the chat, 4 new sensors installed, $240. Should be good for another 10 years..

After replacing my rear pads and rotors and freeing up the locked up drivers rear caliper last weekend. It pretty much locked right up the very next day. So, today I replaced the caliper today. While doing that I noticed my pinion seal is leaking again.
So, after thinking long and hard. I'm going to be selling my Tahoe. Not sure when but before the end of the year. 12 years, man.

 

[j91z28d1]

not sure who on here linked to these quick disconnects for those annoying 3 sided gm clips but used them tonight for the first time and gotta as. that made life so much eaiser. one side line is in a horrible spot to get the clip out. these slid right in twist and pull

Seems like a waste to sell it over that. Hell, Thats how I know my truck still has fluid is all the leaks lol.

 

[91RS]

Yeah, if one seized caliper and a pinion seal was all that went wrong with mine, I’d be the happiest man on earth.

 

[j91z28d1]

I'd take a pinion seal over any other seals like rear main or oil pan haha.

but when you're done, your done. I get that.

Yes Sir,

Bi-LED projectos from amazon.

Cut off the wires that used to go to the Ballasts. The yellow one is power the black is ground. On the projector the red and yellow get tied together and black on black.

For high beam there is no polarity so you hook up the original wires to the two black ones on the projector and then you either leave the ballast there or you find a nice thick piece of foam and you stuff it in the opening to prevent water intrusion. The rest is easy, reinstall, reseal with butyl or silicone or whatever you got handy and you enjoy them.

My favorite part is now the auto high beam it works very well. It didint seem to work well before due to the weak output of the headlights.


The beam is wider and goes farther than any OEM HID projector that I have seen. The old oem unit is hella based so it has a good high beam but hardly any width.

Because you drag all the dry crap, scratching your windshield and embedding it into your wiper. Thought that was obvious.
Apparently GM and everybody else doesn't care. It's only a problem for the afflicted, like me and @Scrappycrow.

Granted, the wipers work. Perhaps the dry wipe is more effective, and it's just a placebo effect, idk..
But wiper blades seem happier when wet, imho.

Lmao. I just replaced my 17-year old windshield in my Tahoe due to a crack. it definitely wasn’t scratched from dry wipers being dragged over it for those 17 years. And BTW, I was a journeyman glazier for a good part of my career, which is a trade that works with glass and architectural aluminum. I can say that rubber being dragged across dry glass will never scratch it, not even come close. You would have to drag something harder than glass, like gravel or something, and with downward force, which a wiper blade wouldn’t do- it would just push it forward. You’re not afflicted with anything other than unfounded fear. So I’ll continue to not worry. carry on!

Considering I can see the wipe pattern in my back glass, I'll believe my eyes.

It's not the rubber against glass, but whatever the rubber drags. Drive on gravel? Hard dust.

Maybe you don't let enough dirt accumulate if you wash your truck more often.

--------------------

Or MAYBE it's my imagination, because my back glass doesn't look scratched in the sunlight.. idk.
I had rock chips aplenty, so replaced my windshield last year...

I read somewhere you can have your glass polished ?

My rear glass is scratched to hell from the rear wiper. I am sure it's from the dirt back there. I deleted that rear wiper a few years ago.

 

[j91z28d1]

every windshield I've had replaced makes me. realized how absolutely haggred my old one was.


and while I'm no glass guy, I'm pretty sure dragging sand across glass scratches it over time.

 

[mountie]

I went to my mechanic this afternoon…. I asked him a question…. About getting a tune.

He suggested for me to remove my throttle body and carefully clean it. FIRST…. See what results I get.
An aged throttle body…. with possible sticking butterfly can affect the ‘launch’ .

Yeah, my windshield is sooooo freaking pitted, that I'm curious if its the original.
