I've noticed that the more frequently I have my targa top off, the more it seems to rattle when I put it back on. Is this a common issue with the targa top?

 

I take mine off and replace it at least 3-4 times a week and have not experienced this.

Do you lubricate the rubber molding with the top off regularly? I wipe a silicone spray onto a rag and then use that to wipe the moldings at least once a month if not more. Roof is as quiet as it can be.

 

Might have to try that, not for noises yet but just preventive maintenance. Thanks!!!

 

No problem here. . .

 

I've just started experiencing the same problem. Can't seem to stop the rattle. Applying pressure to the top in the area the sound "appears" to be coming from doesn't stop it.

The top was never removed by the previous owner. After taking on and off approximately 30 times now, the rattle has started.

 

Had the same thing happen to the better halfs 04. Sounded like a dash rattle. Took it my vette tech and he adjusted the retainers. No problem now.

 

I chased down a rattle in a newly installed glass top this weekend, drove me nuts for awhile. Would rattle and pressing/holding down on and/or applying pressure would not stop it. It turned out is was not an up/down rattle, but rather a forward/backward rattle, if that makes any sense. The clamp base on the roof was too close to the striker plate on the windshield and they were moving back and forth, hitting each other. I loosened the torx bolts on the clamp on the top, moved it back about an 1/8 of an inch and no more rattle.

Patches from this forum sent me a doc on the 5 adjustments you can do to roof panel, pasted below:

Roof Lift Off Panel Adjustment
1. Perform one or more of the following five adjustment procedures to properly align the roof lift off panel.

Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

This is good info. I have also tried pushing up on the roof and the rattle continues. I'll check out the front-to-back motion for the rattling.

Thanks for all your input. This is the only place to go for advice

 

Agree with the above posts. Try to adjust it. Thats what I had to do.

 

I've not had this problem with mine. May want to check the latch area for tightness.
