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

[Just Fishing]

Control arm's probably won't make it for today, but my new lifter pre-load sounds amazing.

Is this "dry rot" around the outside tread of my tires? All 4 tires look the same, it's only along the outer tread. The rest of the treads have life left, but the manufacture date of these tires are 2016.

We plan on taking a road trip next month. Was planning on getting new tires afterwards, but now seeing this, I might do it before hand. View attachment 371866

Yes. They all do that after a few years. The ones on the avalanche are way worse than that. Replacing them in a month or two

Stupid tab broke off the dash trim so I drill the hole and zip tied it to the main dash. Going to need to order some parts…
@iamdub remind me how you supported your center speaker…

Sorry, but that wasn't me. I don't have a center speaker. All I've done is epoxied two cracks on the dash- the one on the right side of the gauge cluster hump and the one at the forward left of the passenger airbag. This was years ago when those were the only two. There are more now and that front piece is even more fooked.

That was @Doubeleive ,I do believe, lol

I've done it also. Pop the grill off with a plastic trim tool and the speaker is mounted with screws in the corners. Remove the speaker and tape/glue/etc a thick piece of that grey/black cushion foam to the bottom to give the speaker support from underneath. Can't remember how thick, probably best to measure.

I had at least 10-15 of those notices and a couple more came after I had it done, lol

#metoo

Ive been waiting for the parts to be in stock so I can take them in.

If you pull the speaker out and look down in there it's not a flat surface under there it's angled a bit so I just cut some styrofoam to fit so it would support the bottom of the speaker and I put epoxy around the screw mounts for the speaker because they crack as well. They must have had the village idiot design the dash and then chose the cheapest vendor for the plastic. I mean it doesn't take a scientist to figure out hey this might break from bouncing around going down the road, maybe I should brace it, hell even a single stock of plastic under it would have helped.

It is the worst design! I had the speaker out but ran out of time to do any more. I will come up with something some other day. I might squirt some expanding foam into a ziplock and let it self level…
Will do a test bag first of course!

All buttoned back up and all maintenance done, so unless something flat out breaks then she should be good to go for a long ways View attachment 371953

Where'd you get the blanket that's around the battery?

Where'd you get the blanket that's around the battery?

it's a corvette battery cover/insulator, I think I have both battery's wrapped in insulation also, it's my feeble attempt to try and keep the heat deflected.

Got some factory chrome wheels and polished up the best I could. Got the stereo install done as well. Now I sit and research go low parts.

Doing the seat back cushion swap. Very easy.

Awesome job on figuring out they can be swapped. My passenger side is like new. I may do the same

Yup same part numbers for both sides. Even swap, feels so much better.

Looks good, mine are worn, scratched and smoke style on black truck, were there when I bought it.

I replaced both the foam and seat cover. I sit about 1" higher now due to the new foam.
Bummer though. That gear I showed was for the driver's rear end seat lift. I replaced with Gruven brass gears. Doesn't seem to be binding, but it seems the motor doesn't have enough oomph to raise my 195Lb butt. I have to stand outside to raise the seat. Goes down with my rear on it. Do the motors get weak?

Thought I would post an update. Back in March i asked Gruven about it and they offered a refund on the gears, but I already had it JB Welded on, so. I noticed last week that the seat does now lift with me sitting on it, before I would have to stand outside. During installation it did not seem to bind. My guess is the motor was weak and has recovered.

Or maybe the gears needed some breakin.
I wonder if it would have helped to cycle it up and down with out a load for a while.

Let those gears bed in.

Last weekend
New parking brake shoes, tire rotation, oil change, greased the brake caliper slides.
Still going to need to order new calipers(they've been squeaking most likely because the dust seals on a couple of the Pistons are torn and filled with a brake dust and dirt and whatnot.
Found the rear diff cover leaking-potentially a broken seal... have to find out if tightening the bolts down health or made it worse. Use the felpro gasket, but when I tightened it down it looks like it started to squeeze out. Unfortunate the 14 bolt doesn't have the rubber and steel reusable gasket like the 10 bolt.
Engine oil cooler lines seem to be leaking somewhere on the short little rubber lines.
The starting battery needs to be replaced again. My fuel line for the flex fuel sensor needs to be remade-seems to be seeping fuel occasionally. Found a lower control arm bolt a bit loose also.


Also, those replacement center caps I have are already looking like crap, cracking from being over tightened and the threads on the plastic nuts are starting to disappear, the bow tie in the middle is all foggy.
Ordered some of the ppv center caps off eBay.
They're a little beat up, and I think I'm going to repaint them with silver steel-it which should cover up some of the scratches not that I'm too worried about that, but also match the wheels a little better.
I do need to get bolts and spacers and drill and tap the wheels though.

Buy a Lube Locker gasket for the rear. $21.95 at Summit
