[chevyguy69]

Has anyone ever found a fix for the rear cab wind noise for Crewcabs 2008 and up?? I have tolerated it for 6 years and am going to sell it if I can't fix it. I should have bought ans extended cab! TIA for any help.

There is a service bulletin which involves replacing the rear insulation pad under the glass behind the rear seats plus adding filler and sealer in specific locations. It made quite an improved difference on my 2010 crew cab!

Thanks!! I never received the bulliten. How would I find out? I bought it new and the dealership shut down.

It is a "Technician Service Bulletin," the type that only GM service technicians get. I have a copy of it somewhere, and will try to find locate it this weekend.

 

I would suggest contacting the next local Chevy Dealer's Service Department inquiring about the issue.
