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

[iamdub]

Washed it then removed the roof rack then washed the roof again.

I didn't know the threaded inserts stuck up as high as they do. The caps I painted aren't gonna be nearly as low-profile and clean as I was expecting. By my tolerances, this is HUGE:




I cut the stem off a plain, non-painted cap to test. I planned to apply a thin layer of urethane to seal them and fill what I thought would be a really thin gap between the cap and roof. This gap is about the thickness of a nickel, so the sealant would really show:




And these are definitely NOT blind holes!:





Anyone have any suggestions for removing the footprints? I only have polishing compound and it's not abrasive enough. Should I get rubbing compound or is there something better suited?




I'm REALLY tempted to just put the rack back on until I can regroup with a better game plan. For now, I put the screws back in with some black Permatex under the head and ran them all the way in.

Put in an OEM USB port in the front center stack, now I have clean phone charging options. I have an idea for a wireless charger, but not sure if I want to cut up my console insert just yet

Added a Black Friday light bar to the push bar. Also found a used Diablosport s1000 module for $50. I read that’s it’s basically a rebranded Range AFM. The module really woke up the Suburban and acceleration and ride feels much more responsive and smooth. I am noticing a decreased fuel economy, but it could just be me having more fun stepping on the gas pedal...

A tube of silicone is so much cheaper and better looking.

Wow!

Can you put one of your extra tree rivets in a drill and spin it while holding it up against a file to turn it down to the same diameter of the insert? Would that look any better?

That the inserts aren’t blind is a surprising discovery to say the least.

Looks like I might have some serious issues on my hands.... And yes, that's oil

PCV valve sucking up some oil?

rod vault????

 

[DaRosa218]

That's what I'm thinking, going to order a new valve cover with the updated PCV system and add a oil catch can

That sucks. I don’t understand why GM went to that system of fastening the racks on the NNBS. It’s the first I’ve heard of it actually. I would be tempted to get an Esky rack and PTM and just leave the cross rails off. That would look cleaner to me than those huge rivnuts sticking up plus that would provide better protection against leaking since there’s gaskets involved.

Yessir! Hope that takes care of it!
