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

[kbuskill]

I received 3 of my 4 new rims and tires today... Fed Ex says the other one will be delivered tomorrow... go figure...

Any way... I posted how I have already started modifying them in my "Mod" thread found here if anyone is interested...

So what are the best spark plugs for our trucks? I figure I'll do the plugs and wires when I do the headers, since I watched a couple of videos on the subject...

I would suggest going back with the AC Delco Iridium plugs... that's what I did.

Hard to argue with a 100,000 mile plug.

Havent been on in a while, and havent made much progress with any mods yet due to life. But I did get out and do a full detail on the Tahoe today.

I bought a bunch of products from Chemical Guys, and finally got to use them.
Wash- CG Honeydew
Sealant- CG Whitelight
Wax- CG Liquid Wax
Used CG V07 on top of those and wheels
Interior- CG Silkshine (love this stuff)
Leather- CG Leather cleaner, then CG Leather Conditioner.
I think the results were pretty good.

They do make good stuff. I just switched to their Honeydew wash soap and it’s great plus I consider it a good value since it’s so concentrated that I don’t use much, plus I recently bought their stain extractor which worked great. I bought a gallon of Silk Shine a long time ago and it works great on plastics and vinyl. It’s great stuff lol.

I love the SilkShine. When I run out of this bottle, I'll order the gallon of it.

Interesting thought, but I don't really see how that could be happening. With the drop spindles, none of the suspension angles change really. Only the axle angle (if AWD/4WD). You're simply moving the wheel bearing/hub up 2". I had my alignment checked after installing them and it was still dead on.

The only thing I've read about the McGaughy's spindles is that you lose a little full lock turning radius, which can be easily remedied by grinding down a little material off the spindle.

Don't think that's related to what I'm experiencing though as the issue isn't happening when only at full lock.


I suppose my three potential courses of action right now are....

1. Try to get access to a Tech2 (or similar) scanner that can read/record the individual sensors data to target which corner is the culprit, then go from there.
2. Throw another set of wheel bearings/hubs on it and cross my fingers it wasn't wasted money.
3. Put the factory spindles back on, deal with the embarrassment of the "squatted" look for a few hours, drive around, see if the problem is gone.

I am going through the same thing at the moment with my Suburban, I chose the Beltech 2/4 drop. I've since swapped out the rear sensors, (No Joy) I have new front sensors, but before I throw anymore parts at it, I need to find someone near me with a Tech 2 scanner to actually see if we can pinpoint the problem.

Replaced driver side exhaust manifold gasket, fixed one of two snapped exhaust manifold bolts as I couldn't fix the very rear bolt that snapped even with the head. Purchased the Dorman 917-107 kit and took care of the problem. No more exhaust leaks and found that my PCV grommet was torn; replaced and runs a lot smoother. Greased all front suspension components that required it, should be ready for a summers worth of towing and camping

Also considering purchasing the Flo-Pro 2506 Big Oval HD muffler as I would like to have a better flowing muffler to complement my intake and tune

Well I made it half way today... still waiting on Fed Ex to deliver my 4th wheel and lugnuts.

I already posted this in my "Mod" thread but thought I would throw it out here as well.

I will just post a teaser here...

I also installed some other parts today as well including the new Gruven heater core T-connectors.

The rest of the pics and info can be found in my "Mod" thread here...

I agree 100%... I have just been waiting until I needed new tires to use that as an excuse to get new wheels... and it finally happened.

Nothing, i did nothing to my gmt900

 

[iamdub]

Since the Auto-Level compressor is locked up, I removed it last weekend just cuz. I then started getting the "SERVICE SUSPENSION SYSTEM" message at startup. Removal of every suspension controller fuse made no difference, so I reinstalled it last night.

While I was under it, I swapped in the Spohn panhard bar. I haven't driven it yet, but I'm not expecting any perceptible difference in handling. I got it for the adjustability for when I lower it.

Not wishing misfortune on you, but it at least makes me feel less crazy that someone else is having the same/similar issue.


I've been out of town for the last few days, so no further progress on mine. Maybe this weekend depending on the weather I can troubleshoot a bit more, but right now it's still a head scratcher.

You need to disconnect the battery first, then pull the fuse, then reconnect the battery. Also, that Spohn part is red so that =10hp.

I read about disconnecting the battery, but cringed at the thought of losing my HU settings. Less work for me to reinstall the compressor!

Unfortunately, I'm only gaining half the potential power from the Spohn bar. It was powdercoated electric blue by the guy I bought it from and never used. I scuffed it and sprayed it gloss black. HOWEVER, the poly bushings are red!
