2011 Hd Extended Cab Feedback

pknoerzer · May 11, 2011

Like the title says I would like some feedback from owners of 2011 HD extended cab trucks. I have a 2002 nbs 2500HD shop truck and my daily driver is a 2007 nnbs 2500HD. Both of these rattle and squeek really bad in the doors. The wind noise is at least a little better with the 2007 but it sounds like it's coming apart just pulling out of my driveway. I just got this truck last fall with only 23,000 miles, but it seems to have had a hard life - the hours one the engine are really high for the low miles. I've cleaned and lubricated the weather stripping, but it doesn't make a difference. Are the new ones any better with the new frame and body mounts? I don't want to pay for this truck for 5 more years if I can get a new one that is quieter and better riding. A full crew cab would be too big to drive around town.

I have one and I love it. My ext cab doors sounded like they are loose when I hit a sharp bump in the road at a angle. I figured out that you have to close the doors hard to not have this problem. I think a simple adjustment of the striker will fix this problem I believe.

There is some wind noise at higher speed but not bad at all. These trucks are not really that aero dynamic. Could be the tow mirrors causing some turbulence. It's not a issue with me.

The ride is superb. GM did a great job with the new frame and body mounts. It rides alot better than my previous half ton Tundra.

Thank you for the feed back. I did find it made a difference closing the doors hard and I had to adjust the passenger side striker, but they are squeeking and groaning more than ever now.

Good luck with your decision. My ride is nice and tight with no dash rattles or anything. I'm anal about rattles. I would test drive one to see how well it rides. I think you will be very impressed.

Mine is only a 1500 so it didn't get any upgrades for 2011 but I do notice when the truck is first driven after sitting the noise from the doors seams worse than once it's been running- In the morning when I leave for work I cross a small intersection in front of my house and the crossover road is torn to hell and the doors make all kinds of noise then, but when I come home at night it doesn't make much noise at all. Or maybe I'm just tired and don't notice.

I took the entire interior of mine out and deadened the living heck out of it.

There wasn't much there to stop the squeaks, rattles and road noise.

There is now.

Did you use something like DynaMat? It seems like the doors and body mount are what make noise on mine.

As a follow up to this topic - I took my truck back to the dealer to check a list of things before my 12,000 mile (GM Certified) warrantee expired. They checked out the rattles and squeaks and got them all eliminated. The truck is as quite as new now.

If anyone is having these issues, I urge you to take it in because GM does have fixes for these problems.

Well after having driven only 6k i only have 1 complaint with the interior noise. When driving on rough roads and when i hit a pretty hard bump i have a rattle i believe its coming from the passenger seatbelt post. It shakes pretty hard and actually sounds like the ext cab door is loose but its not. After searching about this issue i found out about the upside down J hooks on the backseat have a plastic liner that wear out and cause this rattle. Its seems from other forums its a common complaint. You have to take the back seats out to fix this issue. Other than that little annoying rattle i love my truck.
