squeaky cab top

[yellow2k]

Any ideas for fixing a squeaky cabriolet top? It squeaks when you hit bumps in the road with the top up. It seems to be coming from behind my left ear and up.

Porsche uses (999 917 557 00) Krytox lubricant on the main bow to stop squeaks. There are some other aftermarket products that do the same. Apply it thinly to the rubber spacer between the main box and the roof frame (top half open).

Thanks for the reply, sorry it took so long. I am hoping this topic will move back to the top so you see it. I am not particularly familiar with the areas of the top you are talking about lubricating. Could you elaborate a biut more or provide pics? I would really appreciate it. I would like to avoid having to go to a interior/fabric shop or dealership for something this petty. By the way, I have some silicon grease that I use to lube my weather striping. This is basically like krytox, I believe. Thanks for listening!

You will need to:

1. Open the convertible top half-way.

2. Apply lubricant (krytox) thinly onto the rubber spacer only.

Well My 2000 996 cab H/T was squeky and rattling. My Porsche dealer installed a set of new 'Latches' that hold the H/T in the rear and lubricated the front. It is amazingly quite now.

There could be a TSB on this, I am not sure, but take it to your Porsche dealer and see if they will do it for you.

There are a couple of TSBs on the noisy HT issue if anyone is interested.

Loren, you ARE the man. Thanks so much, I will be trying this as soon as I get home today.

Don, I am very interested in the specifics of the TSBs if you could post em.

Thank you very much, fellas.

Edit: I saw the section on here where it lists the TSBs by number. Is there anywhere where I can find the specific information on the TSB?

Patrick,

I would be happy to donate. This seems like a great group that is forming up, and I am glad to be a part of it from the near beginning. I have a couple questions about the forum in general, I'll move that stuff to another thread/forum.

I had a squeaky cab top as well on my 200 996 C4. I tried a BMW product by the name of "GummiFlege" <sp?> to no avail. Maybe because I didn't apply it right, I am not sure. It didn't help.

I took my car into the dealership, and the tech said he lubricated all the seals. It is now extremely quiet and I am really happy with it!

They also fixed a very noticable creaking type sound whenever I turned the wheel and went over a bump. I took the tech for a ride, and he informed me as soon as he heard the noise that it was the "knee-bar". They inserted some felt lining on either side of the kneebar and it took care of that problem as well.

Between my fixed squeaky top and my kneebar being fixed, my car is really quiet (well relatively speaking!)

[yellow2k]

The TSB did the trick, which I am very jazzed about. Very quiet now, esp compared to my last vehicle which was a late model Corvette. What a rattletrap!

I am the second owner on a low miles (8800 on acquisition) C4 Cab. I live in Portland, OR and noticed no top squeaky noise until the temperature dropped. Now with the temp in the 40's, the noise has gotten pretty bad. I am looking forward to trying the Krytox solution and reviewing the TSB. I was pretty concerned about this until I saw these posts. Great site!

I have a 2004 996 cab and the top is squeaky and slow while moving. I have never lubricated the top for the 6 years I've owned it. Does anyone have a TSB or can they let me know exactly how and where (I'm sure there are several places) to apply Krytox or other lubricant as preventative maintenance and to stop the squeaks. Thanks!

[Loren]

Go here and search for "hardtop" - as a Contributing Member you have access to all the TSBs (that we have).

Thanks Loren for your reply.

I apologize, my original post was unclear - I am talking about the soft top squeaking and moving slowly when it is being raised and lowered. Do you have any info on exactly what the lubrication points are for the soft top? Also, while I'm lubricating things, the rear wing also squeaks and moves slowly when being raised and lowered - any info on lubrication for the rear wing?
