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

Also changed the oil and drained the catch can...

Not to bad for a truck with 212k miles on it running a 10k mile service interval.

And before anyone has a heart attack about the 10k mile interval... I run Mobil 1 full synthetic 15k mile oil and have a dual remote mount oil filter setup and run 2 filters that are each about twice the size of the factory filter and an external oil cooler... so that is 10k miles on oil rated for 15k miles being cooled and filtered 4 times as much as the factory filter and with the added capacity it holds 8 quarts of oil so that means the same oil gets cycled through less frequently.


Slapped a couple Neodymium magnets on the bottom this go around just in case there is any metal floating around. I need to get a filter cutter so I can open them up and see what they catch... hopefully nothing... lol

I went with Wade brand in channel visors... I like them because they are a little wider then some and they are made in the USA which is still important to some of us.

I guess you northern boys have vent visors for different reasons than we do down south.

I keep mine on year round and use them primarily for parking in the summer time to allow the heat to escape. You can leave the windows cracked and not worry when it rains, EVERY afternoon... lol

Well this far northern boy leaves them on year round also they’re taped on haha. But they were alread on when i got it. I so like the looks of those wade ones. I may have to check them out.

Yeah, I leave my windows cracked too but we don't get any evening rain. It's usually nice for 3-4 months straight with a slight bit of rain here and there. We don't have high humidity either. Pretty mild weather here, not too cold in winter, not too hot in summer.

So why take them off in summer?

I don't like the looks of any of them, it looks cleaner without. I actually left them off all year this time and was going to sell them but decided to keep them for now. If I don't use them for another year they're gone. I used to smoke years ago and that was why I started using them because I always had my windows cracked. But I quit that habit thankfully.

Im not an ac fan and really dont need it up here haha. So I love them for the rainy days we get.

I finally ordered and got the helper bags installed in the rear of the Burb.

I also realized that the bracket on the axle for the panhard bar was hitting the crossmember above it when I would hit a dip in the road.

I knew something was hitting but assumed it was bottoming out the axle bumpstops on the frame.

So I trimmed the bracket

and notched the crossmember for clearance.

And installed the helper bags.

No more bumping and banging over dips.

How low are you?

 

[kbuskill]

How low are you?

It is Tony's 4/6 kit + the Spohn adjustable Panhard bar. It came off another forum members Tahoe.

Don't know if that kit sits any lower in the rear due to the added weight of the long body.

If it is a 6" rear spring for a Tahoe I would think it would be a little lower on the Burb.

That makes sense. I didn't know you were that low.

 

[kbuskill]

That makes sense. I didn't know you were that low.

I had contemplated going back up a little bit, maybe 3/5, because of the bottoming out over dips and the fact that the rear would bounce really bad over some bridges...but notching the crossmember and adding the bags seems to have fixed those issues.

There is a particular bridge in town that when you go over it there is a long low flat section of the bridge before you reach solid ground. It is concrete and every section they poured seems to be low in the middle so you get a rapid up and down motion. Everytime I go over it, it causes the rear end to start hopping up and down like an old hoopty with worn out shocks.

Basically the rear springs were too soft for my liking. It may not be as bad on the Tahoe but the Burb is a big girl and I didn't like all the bouncing.

I started off with 15psi in the helper bags and it didn't bottom over dips but seemed a little too stiff so I backed it down to 10 psi to see how that goes... so far so good but the real test will be that bridge.

Truth be told... it may not bottom out anymore since notching the crossmember... I may have to dump all the air and go for a ride and see if that solved the issue... but I still like the bags to firm it up.

I will try to remember to post my results after a few tests.

For the record, I plumbed them separately instead of teeing them together.
