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

[Doubeleive]

See, Sam gets it. I change that a few weeks ago.


Soooo, on this note. Mechanic called and gave me the wonderful news. Honestly knew something wasn't right as it's been acting up a little (shifting slightly weird, not that I know what I'm talking about or looking for and probably a completely different issue) but the rear differential gears are shot. Said they opened the housing and a few bits of metal fell out. Said the spider gear was broke in certain areas and (housing of something) was cracked. So they are going to replace it.

Probably gonna cost me half the price of what this tahoe is worth.....
So, my tahoe won't be ready until tomorrow.......

So what makes these break or go bad? Said the fluid wasn't too bad. Wasn't low. The way I drive affect it? I do drive pretty aggressive.

the g80's are weak, eventually they break when it does replace it with a eaton detroit it won't break anymore

Watch out!

First it’s a balm retainer and the next thing you know, you have super charger and a 3” drop! Especially if you let the guys here help you spend your money.

Tru dat.

LOL, it's my camper tow vehicle. Maybe a stripper pole and mud wrestling pit are more appropriate. The Denali does have new wheels, but all I did was pay for that and the Bee mod was all labor and really hard brain work figuring it out.

Told me a new rear axle would be $3,500, I said no thanks that's as much as my Tahoe's worth

I think I would look at wrecking yards. Pretty sure you can buy a duplicate replacement used for under $1000 for the whole kit and kaboodle. Not real difficult to install.

that's a lie a axle is only $200, you must mean a entire rear end which still seems high

Look on RA to see what a reman runs. Iirc they run 1200-1800 and they take a couple hours to install.

Yep yep, thays what happened...I started reading yalls thread and 10k later, new engine and blown

You’re welcome!

I agree, really high for the whole rear end.

This pretty much what google pointed to price wise. He's replacing with oem gm and that price includes labor.

I don't have the means, time, or knowledge to install this. If I did, it might be different, but working as much as I do, and this being my daily, it's the best choice for me.

Sure, I could do a reman or junkyard, but I'd rather have brand new and at least a years warranty.

All in all, I'm ok with it. I trust him not to screw us over, one of the most reputable shops in town and hard to get in on short notice. He has always cut costs for me and gave me discounts or free stuff, so I don't mind if it costs a little more.

Funny how that works out...

I've got a vibration issue.

Over about 80mph the truck has a little vibration to it, noticeable in the steering wheel. It's not terrible, but doesn't inspire confidence in driving those speeds.

Wheels have been re-balanced. Tires rotated. Alignment performed (twice). Entire front suspension is new.

Any other ideas? Steering column bushings?

Does it sit for long periods at a time, like for a few days? The tires could have flat spots in them. Or they're just faulty. Balancing only does so much- you can balance a square, but that doesn't mean it'll roll smoothly. You might could try having them road force balanced. I'd start by pulling them off and really cleaning the contacting surfaces. It could be a slight bit of runout from crud between the wheel mounting surface and rotor.

Well dyno day.........went well

412whp and 415ftlbs on E85 (only picked up 2hp/5ftlbs on E85)

Super happy with it now its dialed in. Now the 6.0 build begins......its going to become a iron block LSA. Bored to 6.2 and run LSA pistons, rods and rings; and keep the stock 6.0 crank since its good up too 1000 hp.

Going to finish my LSA blower, sell it, then have the motor and heads done. I'll drop that in and then either go with a Procharger or Whipple.

I just finished my lsa install. The car boogies now and she whiny!!! Hoping to be high 10s low 11s.

Today I did my first major mod. You see, my Burt's Bees lip balm keeps flying out of the useless cubby in the dash and fortunately gets captured by the grooves in my Husky Liner floor mat instead of rolling under the seat. I took the Bee by the antennas and created a dam(n) so Burt will no longer escape.

You need to start a build thread.

I should've mentioned, I did have them RoadForce balanced just this week. Though I was a little disappointed that they just added weights to what was there (they did not remove everything and start over).

The rotors are old and very rusty. I could see the "scale build-up" being the problem.

Got a pile of parts from summit today.
Still waiting on the wooden crate to get dropped off.

The Road Force balancers are awesome, but as you probably know, most shops are too lazy to correctly use it. A proper job would be to dismount the tire and start with measuring just the wheel alone for runout and imbalances. Sadly in my experience most shops take shortcuts.

I too have been a victim of the g80 grenade. My 00 Silverado had it. I was young. Donuts galore. Dry pavement donuts. Also towed heavy stuff in some mud. After that, explosion. I forget the total but it was around that range your listing. That was with me working at a Chevy dealer at the time too. So employee pricing still was that much but with new g80 and bearings. Ring and pinion was miraculously fine. It was so bad that when in park, it would still roll.
I didn’t have time to do it myself or I would of gotten a junkyard axle and upgraded it from the g80.

What size pulley are you running?

 

[1BADI5]

Why PC or Whipple, as opposed to Maggy?

Well PC offers a nice program to upgrade the head unit and Whipple offers a 2.9L.

Plus the PC weighs less, less wiring and no additional coolant/cooling system.
