911/Q45

I've always been pleased that my windshield never made the infamous "squeaky" noise and delayed replacing it , despite horrendous etching, until it was completely broken. Once it was replaced, despite extreme care on the part of the tech, it made the noise. He was ready to pull it off and try again when I suggested we try the Porsche urethane foam that you can pack in behind the rubber trim(I had gotten some years ago, just in case). He was very skeptical, but agreed we had nothing to lose. We filled all the space we could, including double thickness in areas that permitted it. It was completely successful and he got the part # so he could stock some foam from now on.

Do you happen to have those part numbers? I had my windshield replaced a few months ago and I haven't noticed any squeaking until recently, perhaps because it's been a little cooler.

TIA.

996 541 903 00 Just lift up the edges of the rubber trim and stuff it in the space underneath.

Your lucky, most glass installers don't even bother glueing the windshield into place nevermind trying to fix the squeak. In the workshop manual for replacing the windshield there are a few pages AFTER the installation instructions that suggest using the Porsche insulating foam.

is that part no. enough to do the whole windshield?

911/Q45

Plenty, maybe even enough for two.

What is the real cause of the squeaking?

I discussed this at length with my apparently quite knowledgable glass tech. He cautioned that it's conjecture, as he knows we fixed it but can't be sure we know what was wrong. His best guess is that the plastic trim that surrounds the windshield as part of the assembly rubs against the rubber trim piece that fits into the plastic. The windshield constantly moves while driving, as it "floats" on the urethane caulk that always stays flexible. Evidently the packing that we add to the gap in there makes the connection between plastic and rubber just enough firmer to stop the squeak.

I must be slow on the uptake. Where do you put the urethane? I couldn't tell from the discussion or the drawing.

Just ordered the urethane foam with the part number given above and got back rubber cell moulding NOT the urethane foam cartridge- this rubber cell is what my porsche techs have been using with it coated with slicone! Whats up here-

911/Q45

It should be about 12' of grey urethane solid tubing about the diameter of a pencil. I wouldn't coat it with silicone, as you want it to stay in place and keep things from rubbing and squeaking.

JasonAndreas

That's what they use on the 996 but for the 993 I believe the part number you want is #000-043-203-48. I have never ordered any so double check with your dealer beforehand.

Various foam and silicone cord is available here as well.
