I had the exact same problem on my 2014 High Country sunroof. The bellows piece of rubber on the passenger side would constantly come loose, and fall off. A little bead of clear Gorilla Glue fixed it. With that said, you'd think that for a $50k truck, little crap like this wouldn't be an issue.

Yes. The very LOUD, noticeable "metal-on-metal" sounding rear-end clunk has also been eliminated, I believe through a combination of asking the service manager to have the torque checked on my leaf spring u-bolts, in combination with a transfer case program update.

GM should include this type of thing in their Top-Of-The-Line truck offerings (High Country & Denali).

It's been raining like crazy here in Northern California, which we need DESPERATELY, so no complaints!!!! Looks like we're going to get a little break tomorrow and Thursday though, and if it happens I'll head to O'Reilly to check this deflector out. I've also got a height consideration where I live, to get into the covered parking area. I'll report back after doing some research. Cheers - Rick

Thanks for the info, pictures and the direct link to the wind deflector you got. I really appreciate it!! Gonna go grab one @ O'Reilly later this week. Cheers - Rick

I've searched here, and only found this one thread (http://www.gm-trucks.com/forums/topic/173591-sunroof-deflector-options/?hl=sunroof), but it offers no real help. Wondering if anyone has found a solution the the Ridiculous amount of noise the sunroof makes at freeway speeds? I checked out AutoAnything.com, and there are a few options, but no mention of Silverado owners in the comments section. Hopefully someone here has discovered a wind deflector that works to cut down the wind noise. Thanks - Rick

Well, I'm beyond Happy to report that my drivers seat movement issue is now GONE!!! I didn't pick-up the paperwork when I got my truck, as the Service advisor was swamped and said he'd mail it to me. Once I get it, I'll post a copy of it, showing the TSB#. Rick

Just got home, and didn't feel any more seat movement. With that said, I drove straight city streets and freeway the whole way home. The true test will come next time I'm heading out to the coast, on Hwy 1. I'll report back soon.......

Update - Couldn't pick my truck up last week, but hopefully going to get it back today. Will report back on the seat movement "fix."

Unfortunately, they're doing the shim kit repair first. If that doesn't work, I told them I'd be back for the seat bottom frame replacement. The Service Manager told me they have done this repair several times for other customers, and none have been back complaining about seat movement. Time will tell......... I pick the truck up on Wednesday and will report back. Rick

Oops, my whiff - you're correct 78 ft-lbs.

Update - I'm taking my truck into a different Chevy dealer service department tomorrow morning, to have the drivers seat movement issue fixed, under one of the existing TSB's out there (#13310A, PI1183A, or 15304). The service manager I talked with seems like a pretty knowledgeable guy, and ordered the parts for the movement issue beforehand, so they won't be waiting on anything when my truck arrives. I'm also going to have him check the torque on my u-bolts, to be sure they're at the correct factory tightness of 78ft.-lb. We'll see if it will help the "clunking" in the read-end when I'm coasting, and then re-apply the gas. He's also going to check that all of the factory updates for the transfer case have been applied. If nothing else, at least this will be the 2nd service visit on record for the rear-end "clunking" issue. I'll report back in, once I've picked-up my truck. Happy New Year All - Rick

The two TSB's I've found relating to seat movement are: #11310A, or #PI1183A. Rick
