Recently my targa top has started creaking on the drivers side. When I push up on it while I am driving down the road it will stop. I think I read somewhere that you can adjust the latches somehow. If anyone knows how to stop that creaking please let me know because it is driving me crazy! Thanks

 

I have heard about the adjustment, but unfortunately I am not sure how it is done though. On my old camaro, using silicone lubricant on the t-top seals reduced sweaking/creaking dramatically. If the adjustment does not help you might want to try.

Corvetttedoug,

I have the same issue and it's driving me crazy! I also rember seeing a thread on the creaking but could not find it in the search.

Common guys, has anyone else had this problem and found a solution?

Many thanks.

 

Check the pin sockets behind the driver and passenger shoulders. (part of the car, not the targa top) They are screwed in place, and the screws can come loose.

I found two things to adjust in the service manual. Unfortunately I can not figure out how to add an attachment. The directions are much easier to follow with the diagrams. I will post the directions anyway minus the diagrams. You might want to look on Ebay for a service manual or just get a set of the cds/dvds that contain almost all manuals for 98-05 gm vehicles. Good luck.

Roof Lift Off Panel Adjustment
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.

Right there will do it, also check the weather stripping on the panel and the car, they tend to get pinched and damaged easy.

 

First try dilectric grease (just a light coating) on all top weather stripping.

 

...also...remove the roof panel and apply dilectric grease to the ends of the two locating ball-end-pins that insert into the roof bow. I had same creaking, found this completely silenced it. Just a suggestion...
