Rattle noise in front end: 2005-2006 Equinox

Rattle noise in front end: 2005-2006 Equinox
I just wanted to share two items I found regarding a rattle in the front end of the Equinox. One can be heard, while the other can be heard and felt. I own a 2005 Equinox FWD.
The first is the one that's heard and felt in the steering wheel. It's the steering knuckle, under the dash. The knuckle sits between two shafts, and rests on splines. If you take the lower plastic cover off the bottom of the dash, (dash to firewall, NOT under the steering column) There's a TSB on this, but the number eludes me at this time.
You will notice play (linear) in the steering shaft which causes the rattleing noise when you drive over bumps and during braking.
To repair: Loosen the top bolt that regulates how far the upper shaft is slid onto the coupler. Slide the coupler up as far as it will go, and hold it there while you retighten the bolt. Replace the cover.
The second noise I heard after that, was a faint knocking noise from the front end, when hitting bumps, but ONLY with the brakes not applied.
This noise isn't harmful, however, annoying to me. As it turns out, there's a TSB on this and the fix is are redesigned (perhaps larger in diameter) brake caliper pins. The TSB is 05-05-23-005A, the part number is #15824369 for the kit.
To repair: Simply replace the hardware, lube the new pins with silicone (not antiseize or grease) and upon reinstall, torque the hardware to 32 ft/lbs.

Also, there is a TSB out for rattling when driving over bumps/rough roads at slow speeds. This applies to 2005-2007 Equinox/Torrent and the fix is to install a revised rear bushing on both of the front control arms. The TSB specifies p/n 25823014 which has since been replaced with p/n 25919637. These bushings are currently only available from a GM stealership, 'er I mean dealership.
Our Equinox started having this problem shortly after the warranty was up, and the sway bar links are still good. The bushings are currently about $52/ea +S&H from gmpartsdirect.com so we've just lived with it as it's not a big deal.

Don't use silicone on the pins. High temp anti-seize can be used in a pinch, but a high temp brake grease is recommended. High temp brake grease is usually silicone-based, but is not simply silicone. I think this is what you meant.

My noise is minor, and only does it with the brakes NOT applied. Even the slightest brake pressure, and the noise stops.
Yes, thanks for the "silicone" correction. Didn't mean to misguide anyone.
I read something about the bushing. I'll have to look into those as well. I understand the torque amount for the control arm may have changed as well on reinstall....

Another good example of this is the upper engine mount for any 1992-2002 Saturn S-Series. Saturn first used a "solid" design of this mount that is pictured below.
Then Saturn switched to an inferior design sometime in the late 1990s which came to be known as the "frowny" design pictured below.
Then they ultimately decided the first design was better and went back to it in 2001 per Saturn TSB 01-T-30A.
Now, the only way you are guaranteed to get a solid design mount is to order p/n 21012185 from a GM dealership that is an authorized Saturn Service Center. The most popular aftermarket engine mount manufacturer (Anchor) still to this day only produces the frowny design despite Saturn advising not to use it over ten years ago. Some people (including myself) have been able to get a solid mount from Autozone that is manufactured by DEA and sold under AutoZone's house brand "Duralast". However, one must look in the box before buying it because a frowny mount may be in it.
