Here's another idea that might work in these tight fit situations.
Get some shim washers with a 5/32" ID in various thicknesses [ .005, .007, .010, etc. ]
If you have cutters, snip the washers as shown so that you have approximately 1/8" opening:
The idea is to just prevent end-play. The roller may or may not turn when using the latch. If it doesn't, just make sure there is a small amount of grease on the latch ramp so the roller will slide easy.
Good Luck!

Just wondering if you roof is nosiless. I did the (1) ring on each side (both latches) but the noise was back again in a couple of days. I then tried an ering on the other side of each roller so there was one on each side. The noise is back again! CRAP!

I'll try them out this weekend.
Thanks!

Mine has been great with this fix, money well spent (all $1) hehe.
Even told my friend, a Chevy tech, who may point some bithing owners to this until the real fix comes out.
Fantastic solution and many thanks.

If it is verytight to turn the latch to lock it, then there is something else going on if you still have the noise......

UPDATE - ADDED VIEW TO HELP WITH INSTALLATION....
3/4 update - 75 miles and not a sound....
3/8 update - 200miles and still good
3/14 update - 350 miles and still good
3/18 update [last one] - over 2 weeks and not a sound
Glad this has helped out!
My '05 didn't have the popping of the roof panel until I drove over some rough construction areas.
I read all the threads, and it seems the culprit is [mostly] the roller in the latch.
One recommendation is to jam in a small nail or staple to prevent the roller from moving. I did that and it seems to work, but I frankly could not see why preventing the roller from rolling would eliminate the noise.
I experimented, driving the car with the latch totally disengaged, and also engaged with the latch stopped on the tightest point, just before the final latching. In both cases, there was ZERO noise.
I believe that maybe it is the axial movement of the roller as the body flexes that creates the noise - either the roller moving on the pin, or actually bottoming out on the latch cradle.
[thanks to Y2KC5NBM for the original picture]
I looked at eliminating the fair amount of end play on the roller. I bought a pack of 5/32" E-Clips from Lowes. The clip snaps securely on the pin, and is just the right thickness:
I installed one as shown:
The thickness takes out virtually all the end play, but the roller still rotates as it should.
So far, no noise after two days - easy install, don't really have to remove the latch, but that makes it easier......

Thank You - cheap fix for $1.27 and only about a minute or two to slip on around the latch rollers. I've gotten so used to the popping noise that I did not realize how annoying it really was. Thanks Again! Wayne

I just got back form the Bash at the NCM where I attended the Quality Clinic. The engineer I was working with replaced my latches with a new pair that had the rollers epoxied in place. This also appears to solve the creaking problem.

Antone know if the dealerships have gotten any word from the factory on this problem and/or the fix?

Never really had any real issues with the popping. Once in a while after sitting in the sun I would get some but it went away after a 100 meters of driving. BUT, my friend Wayne did it and suggested I try it as a preventive measure. Bought the clips and had my friend Tony talk me through it via phone. Easy to do and if it prevents the popping in the future .... all is good.

It's now been 3 weeks/500 miles since installing the clips on mine, top has also been taken off and put back on twice. Totally silent.
UPDATE 5-19-2008: One month, 1620 miles, top on & off three times. Still totally silent.
DISASTER 6-20-2008: Two months, approx 2,000 miles, top is popping again.
