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

[Thouse]

To anyone following along the dealer called me this morning to inform me they would be replacing the ISS and bearing.

I am very interested to see if this firms up the steering.

Funny side note. The salesman who sold me the car wrote up the due slip for "clunking" and kept rolling his eyes at me for being insistent on it. Stating things like "this is normal for a truck this age "

Of course I got two emails from him instantly after purchase asking for 5s and to call him before giving him anything less. I am tempted to give him a shit review.

Thanks everyone for helping me learn and helping me identify that the ISS commonly failed.

Most common issue in all 99-06 trucks and SUVs. Tell the salesman you want an apology and a paid pizza for dinner.

My 05 silverado had same issue and my 03 tahoe does now. Need to fix it but keep putting it off. Not really damaging just loose. Could drive it like that for the life of the truck and nothing would happen. Just annoying when driving.

1/2 hour job to exercise it and you're good for a long while. Mine lasted just shy of a year, I think.

Also, never get a paid pizza. Always go with something good like pepperoni or sausage.

Yea I know the oem part is junk and they go out with the quickness. And I know it's a fairly easy job. New part lasts forever.

And everytime I buy a car I already know its gonna take at least 3 hours of ******** and waiting. So before signing I tell the salesman I want a detail/wash , full tank of gas, and a pizza while waiting. I've done it a few times before lol.

Mostly it was this embarrassing creaking noise when turning. It wasn't super loud but it was always there.

I had read that the ISS could eventually fail completely causing bigger issues? Is this not the case or just something that happens many many miles down the road?

OH also I remember reading that the doorman part was original and the AC Delco ISS was better. I did ask (I didn't tell them too) and they are putting the AC Delco ISS in.

I have not heard of a catastrophic failure. There is an updated design, however. The grease settles in the original design. You can redistribute it ,but you can't just pump more in there because the shaft is designed to collapse in a front end collision so you don't get a steering wheel through your face.

The bearing is where the difference in dorman vs delco commonly rears its head.

If anyone is interested in led lights for the highs and lows please start up a conversation with me. I have highs and lows plus foglight bulbs. Just took them off a 2002 Tahoe. I can text you pics.

As far as firmness don't count on any change. I have recently changed the upper/lower intermediate shafts and the steering box with little change.
