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

[Drok]

Man, I can’t even imagine having a vehicle that sits long enough to worry about the gas losing ummph. If I can get a week out of a tank, I’m feeling pretty good.

Yeah same here. i drive about 30 miles just to work one way haha.

I’m getting annoyed by this rattle in the rear driver side door on the wife’s 2017 Burb. Any ideas what it might be? Do I need to just tear it apart and see? I haven’t pulled panels on a vehicle this new. How many clips am I going to break?

Replaced Skid Plate And flaking chrome good trim piece today (plus bunch of audio enclosure upgrades, deadening and wiring but that’s another story)

I got tired of looking at my busted skid plate and finally ordered a new one. 4 bolts to remove and replace with new one.

Put to work. Air shocks and compressor working good.

 

[Rocket Man]

Are you going to change them with the heads still in place?

Why would he pull heads just to replace valve springs? I didn’t even pull my heads to do a cam swap AND springs.

Not a why really, just a question of technique.

I guess if you want to go through a bunch of extra work just to be more comfortable? I mean valve springs are pretty easy to do with the heads in place. I can do them in a couple of hours or so. #7 & 8 cylinders are the only two that are a bit of a reach, the others are easy.

I think that's a splash shield. I don't think the plastic would hold up well as an actual skid plate.

Yeah not saving work at all pulling the heads. The head/block/bolt hole cleanup is an hours long job as is on it's own.

Tried to do a 0-60 with all nannies off. Forgot I was in 2WD. Did a burnout by accident all the way down the damn street.

Better today, got a 0-60 in 5.36. Thought it'd be a little quicker but this isn't bad for N/A.

Might dyno tune it to see if I can eek out a little more.

Funny you say that. I’m fabbing a light gauge piece of sheet metal to back it up right now. Not so much for rocks, but other pokey things encountered off the beaten path.

I know it possible to change them in place. I’ve always had the heads off because I was grinding valves at the same time.

Changed the oil and then I got to work on this.

I got that when i first got my hoe.
Everywhere said "auto track II fluid" in the t case.
Me: i happen to have a few bottles on hand, so i used it
Man that t case was not happy at all.

Once i put the correct atf in there, all of the issues cleared right up.

And i kicked the vette out of the garage again.
I need to organize a bit first, but the hoe is about to get the oil pan pulled.

I'm also scoping out some nice used engine hoists.
Found a super heavy duty one not too far away from there, but it does not fold...

Looks like you could pull an entire car with it.

All depends on the transfer case as to which fluid to use. Mine takes AutoTrac II.

Order brakes, whipper arms, sway bar end links... you know the fun stuff

Either @Doubeleive or @kbuskill bought a metal one with louvers stamped into it. Thought it was pretty pricey though, but looked nice.

I bought the OE steel transfer case and front differential skid plates made for the trucks or Z71s and put them on my 2012 Denali. The holes are already there.

The 4wd actuator went.
