What did you do to your NBS GMT800 Tahoe/Yukon Today?

[clandr1]

Oh man does it really light everything up! All my lights are led, which really helps alot too. You also have leds?

Nope, good old fashioned incandescent bulbs. There were 3-4 years I had HIDs in the truck, but I eventually went back to bulbs. Do the LEDs have the same issue the HIDs do where they project light all over, including into oncoming drivers eyes? I haven't really looked into them so I have no idea if they are a true replacement for bulbs.

Some guys will say yeah--I'm not really sure, but I haven't had anyone high beam or flash me at night. I had hids before, so for me leds are a huge improvement in night time driving. I actually couldn't see shit with the hids. Here's my headlight lenses--Spec D.

You guys cost me $25 for something I didn't even know I needed LMAO. I ordered the Fleece all lights on chip from Amazon and installed it last night. I figure with all the money I've saved by not having a car payment for 13+ years and doing almost all the repairs and maintenance myself, why not splurge?

Yes indeed! Love this “mod” couldn’t be much easier.

Very! I take trips out to the country every so often, and it'll be nice to see how my visibility is improved with the low beams staying on with the high beams.

Hopefully you have fogs too..? Then you get all 6 [emoji16][emoji106][emoji631][emoji631]

Yes, both HID’s and LED’s are designed to be used in a focused housing, in other words, projectors.

While each manufacturer does things a bit differently, regarding the led types, and precise location on the “bulb”, this affects how badly, or hopefully not too terribly bad the beam pattern is. And of course, another part of that equation, are the actual housings used. Any non-projector is designed for light reflection from an incandescent source, which has light beams coming out unidirectionally, but since they have silver-painted areas, this actually does direct the light where you want it.

So some are better than others. They’re all really no good for standard incandescent-designed housings though. I’m eagerly awaiting my retrofit order. [emoji16][emoji106]
These will provide both a clear, non-scattered beam pattern, due to the projectors, as well as much-improved visibility.

ok need your opinion on this noise sounds like it is the actual driveline, makes no sense

Finally replaced the brake light switch today. Been needing that for a while. I have had intermittent issues with the CHMSL not functioning.
Then I had another driver tell me about a week ago that my brake lights weren’t working!
After fiddling with it, I verified it was indeed working, but I really didn’t have any confidence, and was always checking and verifying the brake lights were actually working.

I had ordered what I thought was the correct part:

But, of course as soon as I looked on the brake pedal, discovered that’s the [parking brake] switch..

No worries.. I ordered the correct part, which will be here in a couple days, OEM AC Delco... for now, I’ll just take this one apart and clean up the contacts...

That bottom one is really corroded and you can see the metal is questionable....

Well, broke out the brake cleaner, and a wire brush, cleaned those contacts up, reassembled, and wedged back in place..

Did I mention that getting to this thing is a back breaker...? Things under the dash are never fun IMHO, but this is particularly painful. Anyway, this little clip is a mf’er:

After reinstalling —minus that clip— I tested the brakes.... nothing.. I had questionable lighting before, now I’ve got nothing. [emoji23][emoji1787]

After checking all fuses, and checking for continuity ahead of the switch, I determined the contacts must have been too far gone, and when I cleaned them up, I must have removed the tiny remaining metal that was actually working..

So, headed to O’reilly for a Standard replacement. All is well..

Now i have an Genuine AC Delco part on the way, as a backup. I’m not likely to break my back again unless it’s necessary..!

But the best part..?

I can't catch it in slow motion--but you have something in this area. Looks like it's sticking out--

Sounds like something slapping as the ds is spinning. I know-"duh", but that's the best way I can describe what I'm hearing.

there is a little plate attached there appears to be stock might be a weight or something

I saw that too, but it looks like it’s supposed to be there.

That’s a really strange noise.. almost like theres a quarter in the clothes dryer...

Any vibration while driving..?

Are there weights inside the driveshaft for balancing...? That’d be my guess.

Isn't that seized U-joint making noise that resonates in the driveshaft?

Bought some duplicolor Dark Spiral Gray Metallic and clear rattle cans to attempt color matching the end caps on my newly acquired Esky roof rack. If it looks horrible, I suppose I can try and find a small shop to paint it. Not sure how much that'd set me back or if they'd even do such a small job?

 

[Rocket Man]

alright heres the walk around

Awesome. What do the floor pans look like? Seems to be the only issue with ones around here, probably from windshield leaks since they don’t salt the roads here.

 

[Rocket Man]

When I had that problem, I bit the bullet, went to my buddy's shop, we removed the exhaust manifold, welded a nut to the piece of a bolt stuck in the heads with a MIG welder and removed it. Then I installed ARP studs and hope I won't have to do this gymnastics ever again on this truck.

That’s what I’ll do one day. My rear ds didn’t break off, and I replaced the rest with ARP. But I do have 2 clamps on.

When I did mine, I paid a neighbor, who paints and does auto body to do those, and also 2 mirror caps. I fully prepped the pieces first, and I think he only charged me $160.. however, it was a little difficult to match my paint color, as there are 3 variations on the factory “Redfire Metallic” color. He did a test spray for all 3 and we decided which was a match.

I brought it to his shop for the install, and was glad I did, since I also wanted to remove the old stick-on window visors, and replace with in-channel ones. This was a huge pain..! I’m so glad I had him do it. It still took about 3 hours to get it all cleaned up, and done. So I handed him another $100, for his time and effort. Well deserved!

Go to www.automotivetouchup.com, find your color, and order a spray can of it mixed to match. And don’t forget a can of clear coat.

Do you have matched mirror covers? I actually bought mirrors with that color covers, and my Hoe is blue.

nothing is seized, the driveline shop here in town said the (older) aluminum drivelines can get stressed and make that ticking sound and it also why GM started making the drivelines larger size, the one on my Silverado is a big fat cigar. He also said they fill the inside with Styrofoam or something now, seems like a reasonable explanation it shifts and drive fine, no vibration, just annoying noise. If I am lucky the junkyard might have a used one for $100 the driveline shop said they can make me a new one for $500. Haven't priced out a new one yet.

I’m pretty sure I heard Morse code for “PUNCH IT”

lol, It seems to do it mostly under a load in the video I had her put in reverse giving it gas and holding the brakes a bit, without a load there is no noise

100% sure it's not the rear end, like a busted Gov-Bomb?
