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

[Tonyrodz]

I just went to the garage and did the same test (key out, engine off) and it was the same as your video.

Thx for checking it out. I thought it was normal.

You replaced the hubs?

With help of a mechanic friend yes he called that problem out on the spot and it worked. Timkins have been fine ever since

New ambient air temp just cause.

went out to the boneyard and grabbed a few things for the 05 got a window motor, and all the parts for the rear wiper/hatch switch and front control, a rail for the roof rack and found a nice remaned steering box after I fought trying to get a different one out and had put it to the side, walked 2 rows over and found the remaned one already pretty much ready to pluck. swapped the window motor over and fixed that, swapped the roof rack rail on the old one was bent, the rear wiper had got stuck in the up position the other night but I messed around with the hatch and got it to go back to park, the front control switch felt funky so I replaced that first and the dam wiper decided to start working again even when I put the old switch back in, I think the issue is the hatch lock sensor it let me open the rear hatch glass when the wiper was up the other night and it shouldn't so I have all the parts for when it screws up again and the wiper motor. Front end needs to be rebuilt so the steering box was a nice score the existing one is leaking.

How did you get it in for the heat soak? Pour it through the throttle body?

What's heat soak?? I poured some seafoam in the gas tank just for good measure.

The heat soak is done with the spray bottle i will post the link.After driving about 20 miles today i can feel a nice difference in the throttle response and it just runs alot smoother at all rpms. She is going to smoke when first started but goes away pretty quick.

Does Seafoam really work? I hear a very slight 'tick', but it doesn't seem to worry me.
( 05' Yukon 5.3 almost 150,000 miles. )
