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. :p

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.

Has anyone found a steering box with a better feel. I've gone through my entire front end and I would like a more direct feel in the steering like a new car. I guess i should have gone with a new box instead of a reman unit. My HD heim links seem to help with bigger wheels..I just want a firmer feel with no play..

I put in poly sway bar mounts but they don't seem to fit as tight as factory so that may be an issue also. The poly end links are a must if the originals habe failed.

I went looking for a vacuum gauge at Northern Tools and ended up putting some quick release couplers on my Motive brake bleeder. I prefer not to put fluid in the bleeder when bleeding brakes and now I can disconnect the bleeder from the master cylinder and add fluid without losing pressure in the tank and having to pump it up again. I can also quickly switch connectors between different cars without having to thread on a different adapter since I also have a Nissan, Honda And Mitsubishi lol.. .

Not at all related but other than an idler and pitman arm, all the front end pets are original and it’s got decent steering feel and is still tight and direct even with 263k miles

I've driven a 2005 suburban that had a much firmer steering feel to it. Not sure why.

Does anyone know about the steering wheel position sensor and it's affect on wheel firmness?

I just tightened the two torx screws under the steering column cover as indicated in a old post that may improve firmness but haven't taken it out on the road yet. I couldn't feel any different turning it in park though.

I replaced my steering gear with a reman Ac Delco. I'm not sure a new one would be that vast of a difference.

Over the course a year I have changed every suspension component with exception of one cv joint and nothing has improved the feel of the steering wheel. Finally after changing the steering gear my wheel is straight going down the road but has the tiniest bit of vagueness in the middle with some correction over nyc road imperfections.

You're right. clunking completely gone. No appreciable change in the firmness of the wheel when turning.

I'm willing to bet the 2005 has a rack and pinion instead of the pitman/idler arm setup..

Why don’t you like putting fluid in the bleeder when bleeding brakes? It’s designed like that to make it super easy. You just made it harder.
