What did you do to your NBS GMT800 Tahoe/Yukon Today?

[iamdub]

That's exactly what it's doing.
Do you mean the ratio?

The videos didn't show up for me until just now. The only odd noise I hear sounds like that exhaust leak.

With it on jack stands, you can lightly apply the brake until the wheels stop. While holding the brake, lightly apply throttle to get one side to break loose and spin. It's usually the right side that will spin. Maintain steady brake and throttle pedal pressure and listen for noises. Repeat in reverse.

No, the diff type. Not the gear ratio. I'm sure you have the factory LSD, which, I believe would be the Gov-Lock.

How could I tell?

How could I tell?

Do you have G80 as an RPO code?

Unbelievably I don't.

This is what it's doing as I'm power breaking it--applying throttle.

Making the noise everytime I'm going forward to reverse/reverse to forward then powerbraking it.

I think Tonyrodz and I have about the same kind of luck. My dad always says " if it weren't for bad luck, I wouldn't have any at all!"

Could it possibly be the transfer case making that noise? Even tho the prop shaft for the 4wd isn't connected? It kind of sounds like that's where the noise might be coming from--from the front. I originally thought it was the trans.

Weird that none of those RPO codes seem to indicate the rear diff. The VIN decoder (for @Tonyrodz) lists it as a Semi-Floating rear diff, same as what my RPO G80 shows up as.

During the holidays and on vacation one of neighbors is a mechanic. I had him change out the front sway bar bushings, all 4 control arms and most steering components. I used all oem GM parts. I painted all parts black prior to getting the work done. SUV rides like new now.

Where did you purchase the oem arms from and do you have the part number on hand by any chance?

Think of how many of those have been changed from OE!!

I used the AC Delco 45D3174 or GM Genuine 19186776 for the front left lower $143.79 at RA then.

The AC Delco 45D3175 or GM Genuine 19186777 for the front right lower $145.79 at RA then.

GM Genuine 15864153 for both upper control arms. $203.79 ea., at RA then.

Nice upgrades. I did the nnbs shifter in mine but with the stitch in the back. However, I had to swing back around and notch it and bend it in a vice as it hung way too low when in drive.

Here's where the inspiration came from: https://www.gmfullsize.com/threads/how-to-nnbs-shift-lever-in-nbs-trucks.318301/

definitely.. I bent mine in a vice, and now it's perfect..

 

[Tonyrodz]

Well, at least I was able to change the temp sensor--that's how this all started.

Does anyone know if a JL4 equipped rearend is compatible with my non JL4 rear? I might have to replace the entire assembly, and a yard is telling me that it's compatible. Just want to make sure it'll swap on with no issues or modifications.
