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

[Charlie207]

It’s not the boot it’s the terminal clip that snaps onto the plug tip.

This. My 360° terminal clip was only 180° half-moon. But more concerning was that it showed no continuity on two separate multimeters. I grabbed two other wires off the engine to test, and they were fine.

I find once you twist to break loose the seal, wigging back back and forth while gently pulling and they usually come off without leaving the center on the plug.

but something it just happens

Today was an expensive day for my hoe.. I replaced all 8 fuel injectors! It's been having a hard time starting, even after replacing the purge valve. It's also been idling weird, my eyes would burn standing next to it, and after it sat for 3 weeks - I could smell raw fuel coming from the air box. I figure it was a leaky injector, and I was right. I just test drove it after the injector replacement, and it feels like I removed a parachute from the bumper. No pics this time, but replacing fuel injectors isn't very exciting, haha

I looked at thecopcar today. I promised the girl she’d get driven this weekend.

You probably know this, but check/change your oil. It might be diluted with gas. A buddy of mine had an injector stick open in his truck, and it dumped enough fuel into the oil before he caught it to have it spin a bearing.

And after the oil change I'd be watching the fuel trims. They might be a bit negative for a bit while the fuel vapors are being burned, but they should settle in soon.

Put some Welds and new tires on. Unfortunately it does rub a little so gonna have to address that…

 

[Doubeleive]

took the spohn rear boxed lower control arms off and put the stock control arms back on. After replacing the spohn bushings just about a year ago there crap again makes the rear end have a unconformable drop/lift feeling when braking and accelerating, tired of it.

 

[mikez71]

I was going to install APOC trailing arms, but decided I really just want rubber. Plus I don't need or want adjustability.

I just want a beefier lower arm that might survive some impacts better than stock arms would.

Thinking about custom lower arms with stock rubber bushings someday..

 

[LSCALADE]

Who knew that some 10moths after I bought one I would buy a second one.

Escalade 2.0 for me is a keeper. DOD deleted, BTR cam, supporting mods, I absolutely love it.

Here are some pictures.

Had to upgrade the brakes immedietly.
Old ones.

And the 2019 and up 4 piston units.

those spohn bushings do not hold up the last set split in half, maybe I can locate some good solid rubber ones and have them pressed in, all kinds of farming and tractor supply places around here.
Took me a while to figure out what was causing that sinking feeling the first time around, had it at 4wheel parts and they mentioned the bushings were split and then it clicked.

How do the new brakes compare to old?
I know it's never a fair comparison vs worn old brakes but...

There was a couple online reviews where one of the APOC poly bushings pretty much disintegrated. (They do have a lifetime warranty on the bushings)
Possible it was installer error?

Either way, rubber will be less maintenance, smoother ride and last longer I suppose..
I figure I might as well try and weld a couple bushing holder rings to a steel tube if I'm serious..
(New trailing arms are pretty cheap, maybe I can salvage the bushings by cutting or pressing them out..)

Well having done this now on 3 GMT900 in all 3 cases the pedal becomes firmer and does not feel spongy when slowing down, now that could be due to the old system having some air in it but in general the pedal has a nice short travel same as before but then it becomes hard and the more you step into it the more it bites and brings the speed down.

I think that has a lot to do with bigger rotor, more piston area for the pads and more even application.

I would say its a perfect update for a 6500lb truck espcecially if you want to use smaller wheels.

Where did you source the brake parts from? New or used? Were they crazy expensive?

 

[91RS]

The 2019+ brakes are actually pretty great for how little they cost, the issue is how large the calipers are. The K2 Brembo kit fits just about any 20"+ wheel and the 2019+ brakes will fit almost no wheels for 800/900 trucks. We put them on my late father's Sierra Denali since he already had AT4 wheels on it and they made a huge difference, I was impressed. If they fit your wheels, it is a very worthwhile upgrade for the money. I wouldn't change my wheels just to make them work, at that point you can just buy the Brembo kit.

Yesterday I installed new radio in the 07 burban

the spohn bushing are short and push in on left/right side so there is a gap in the middle of no bushing material then a metal sleeve is used thru the center, there just not robust. they use the same bushings for everything

 

[mikez71]

When I look at aftermarket landcruiser trailing arms, they seem to all use rubber bushings..

 

[Sir_Hiro]

I have polybushings in my C10 and I hate them. The bodymount bushings make you feel every damn vibration, The ride is rougher. I refuse to use anything other than rubber for bushings after that.

My 79 T/A had poly leafspring bushings and no matter the ungodly amount of grease you put on those bastards they will squeak.

Ok, I feel a bit silly asking this questions, but I will happily accept being humbled by the answers.

P/N: 15893710 & 15893711


Where do they mount? It’s some sort of splash shield, but I don’t recall where they go or what hardware is used.

Secondly. Is this a mount for a front license plate or is it something else entirely?


Thank you.
