Targa is creaking like crazy and I thought I had fixed it with various talc and lube solutions, but after a couple of days...creak creak creak.

Can anyone offer any advice that works please? And tell me how to do it.

Seems to be coming from all areas of the roof. Fine on smooth roads, awful on bad ones.

Thanks.

Have you seen the TSBs on pcarworkshop.com?

If everything is tight and clean, you should have very few, if any, creaks.

Is the roof properly aligned, and are the adjustment bolts on the axle plates tightened to spec? Are your seals clean, especially the one on the sliding roof that contacts the wind deflector?

I've only had one creak that wasn't mentioned in the TSB. Here's the thread on it.

Thanks.

What's a TSB?

TSB = Technical Service Bulletin. Porsche's way of letting the mechanics know how to fix certain items that needed clarification, fixing or changing in a written form.

Thanks for the tip.

But how ANYONE is meant to make head nor tail of those useless line drawings / illustrations is beyond me.


Any other idea that may be of more help?

Yeah, sell the targa and buy a coupe...That should fix it!

Consider a front strut brace. This will help with some of those annoying noises.

I didn't think they were too bad. Of course, I probably stared blankly at them for 4 hours before understanding any of it. ;-)

First step is to isolate the rough area of the creaking (or one of the creaks, if there are many). Can you get more specific with the source of the sounds?

I thought my Targa top was creaking too but then I realized most of the creaks were actually coming from the windshield. I stuffed the foam "rope" under the windshield rubber (do a search, several here have done it) and most of the squeaking went away.

When the roof is wide open - no creaks. Lovely and quiet.

When the roof is shut, creaks all along the passenger side from windscreen to rear window, slightly less when the wind diffuser is open.

It doesn't sound like rattling or anything loose, more like rubber on rubber.


So when the roof is shut, that's when it creaks.

Thanks for any more ideas.

I am experiencing the same noises. It seems to be heat related too. I don't hear any creaking in the morning and then it gets louder through the day as the sun heats the glass top (or so I am thinking). I've had the car for about a year and didn't notice this until a few months ago. I figure it must be time for a good internal cleaning.

Good start. If the creaking goes away when the roof is open, we can ignore many parts of the roof for now. Also, there are very few possibilities for rubber-on-rubber contact with the roof. Most everything is rubber-on-glass or rubber-on-metal.

Before you get started, make sure your roof is properly aligned. When closed, it should raise to the exact level of the rear glass and be just below the level of the wind deflector. If it's not right, you should address that problem first.

Assuming the roof is at the correct level, I would verify that the axle bolts are not loose. This TSB shows how to tighten the bolts. Be careful. These are very easy to over-tighten, and you will need a thin long reach hex socket and torque wrench to do it properly.

Second, I would try the fix 2.1 mentioned in this TSB. This is the only area I can think of where there could be rubber-on-rubber contact in the area you mention. You don't really need to take anything apart for this procedure. Just pull the seal out a bit in order to insert some lube with a wire. The idea is that the noise is caused by the hollow seal rubbing against itself.

Thank you for that, and the links, most helpful.
