Adjusting the replacement SMC roof – DIY w/pics
The recall instructions were revised on Aug 25 to mention that the new SMC painted roof sits LOWER then the original one and needs to be adjusted.
If your dealer neglects to do this or isn’t aware it needs to be done, here’s some DIY instructions explaining how I fixed mine.
Please note, the instructions in the service manual say that you need to remove the visors and headliner to make this adjustment.
My car had enough of a gap in there to adjust the front mount WITHOUT doing this.
Please check your car out and make sure you don’t have to do this the long way without damage.
When I picked up my car after the SMC replacement top was installed the top was noticeably lower in the front.
The very next day I saw posted here that the dealer is supposed to raise the front roof mounting points 1.5mm to 2.0mm to compensate for this.
I didn’t want to take the car back to the body shop so I did it myself.
Here is what I did.
This is the drivers side front roof mount
Notice the adjustment screw if you pull away the headliner piece
It requires a T25 TORX bit
I pulled the headliner back and slipped the screwdriver into place.
Loosened up the two screws and raised the mounting bracket.
Tightened it up and did the passengers side next.
Roof lines up great now.
Sorry for the dust & fingerprints. She needs some detailing attention

Has anyone tried re-gluing the roof panel themselves? I'm real concerned about the paint matching after the replacement is made. My Chevy dealer just called me to let me know the replacement roof was in. They want me to leave the car so they can make sure the paint matches. They said they have had complaints about paint match on other replacements. Why would that make a difference? Really makes me want to bring the car in. I was thinking about applying a good adhesive myself and just forgetting about the recall. Any advice?

DO NOT INSTALL GLUE.....
BRING IT TO A DEALER ....
HERE IS WHAT WE WILL DO.
REMOVE TOP.
WITH A FEELER GAUGE CHECK FOR GAPS ON THE UNDERSIDE OF THE
TOP.
IF NO GAPS WE WILL INJECT 2 PART EPOXY FOAM..(BAD STUFF)
IT FILLS THE INSIDE OF THE TOP WITH FOAM AND ALSO ADH. THE TOP ON IF THERE IS ANY GLUE SEP.
THE COMPLETE TOP WILL BE REPLACED ONLY IF IT IS SEPERATED.
THEN JUST HOPE THE BODY SHOP THE DEALER HAS PAINTING THE TOPS IS A GOOD ONE...
THEY NORMALY MATCH WELL...ANY WARRANTY QUESTIONS

Mine did and I traced it down to a weatherstrip mounting screw. The phillips head was 'bunged' up. I sanded the head smooth, reinstalled, reset window valet and no thump. On mine it was the rear most screw hitting.

It was the same problem here. In matter of fact all of them (8) where 'bunged' up. Perfect example of the quality work that they do at the stealership...

The SMC on my '07 rides low, especially on the driver side. I was proud of myself after having adjusted it per the above instructions, as the poor fit had been bugging me since the day I first picked up my new car from the dealership. My pleasure turned to dismay the next time I drove the car. Wind noise was then audible at speeds above 50MPH at the roof's left front corner. I readjusted it downwards serveral times, reindexing the windows and test driving after each adjustment. The air leak did not cease completely until the brackets were adjusted back to their original position. I've decided to live with the poor fit in order to avoid the wind noise.

Minor correction
The adjustment screw heads appear to be Torx T27s, not T25s.
Mine were sufficiently tight that using a T25 would have risked rounding them out.

If you look at the picture in the instructions you can see damage to the socket.
