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

[Sam Harris]

I was checking my trans fluid this morning and heard a bit of noise from the passenger side, and don’t hear it on the driver side. Wondering what this might be. Should I be concerned..?

I would always be concerned when there's a distinct sound difference from left to right banks. First would be to check the exhaust. There's less accessories on the passenger side, so that's a bit unsettling. But you could still remove the belt and turn off your A/C to rule those out or at least to remove their noises when diagnosing. Have a mechanic's stethoscope?

Nope. Need to pick one up. ordered. Be here tomorrow. Yeah, first thing I thought of was an exhaust leak. Shouldn’t be, used ARP bolts with the headers, but hey, that would be awesome if that’s what it is.

Found a 17” inch spare wheel and tire on FB marketplace cheap. (Left in the pic)Tire looks as if it never has touched the road. Should clear the NNBS brakes on the front if ever need it.

You should check the date code on it. Looks good tho.

Good point. I forgot to look at that. I just looked at tread and no signs of any dry rot or cracks. And it held air. Of course can’t be any worse then the one I already had. That may have been the original from 05. And was only 16” wheel.

So heard a noise going over a speed bump, I stopped and turned the wheel left to right and noise was worse.
Got home popped the hood and found out the idler arm bracket was loose, was just rocking back and forward while turning the wheel. Tighten up the two 21mm nuts and bolts, but noise was still there. Turns out there is tons of play in the pitman ball joint to steering link, that was the issue. Placed an order for replacement idler arm w/bracket and pitman arm.
