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

[Derick]

Just got back from the burbs 2nd road trip. Getting further and further out while I build trust. Had ~700 miles round trip. Still not very far I know, but I might take it to TN in a few months hauling 5-6k so I wanted to ensure she was stable.

Got her a wash yesterday on the way home. Needed it. Even though there was some crazy rain on Saturday as we traveled, it didnt get all the muck off.


I watched my status along the way, and everything seems right down the line. I'm getting a little lifter noise here and there, but not consisent so I'm not sure whats up.


I've still got another day vacation today, and I'm at the dealer getting the trans serviced. I think I might stop at autozone on the way home and get some gear oil and do the differentials.

Stickers actually subtract HP. Red parts add. It’s been proven.

I did the rear end finally. I had to use a 12mm socket on the rusted 13mm bolts tapped on with a hammer to get them off. I also used a propane torch to help loosen them up. The new Amsoil containers are awesome! Installed new stainless bolts.

Yeah FYI those covers apparently are a special order item from dealers and big box auto parts stores. Plan accordingly; I ordered that one from RockAuto.

These are the bolts I ordered. I would order them them slightly longer.

Hex Serrated Flange Bolt 18-8 SS - 5/16-18 x 5/8" (FT) , $11 for 25

I would get 3/4” length ($18.25 for 25) if I had to do this again even though my 5/8” long ones barely fit well.

Found where a coolant leak was coming from. Anyone know what this part is? Can’t find it anywhere. Located in front part of engine under engine cover. Rubber hose connects to radiator.
