Thread: Famous 911 Door Thud

    Famous 911 Door Thud

    My 1973 passenger has always closed like a vault door - strong solid thud.

    My driver door has always been just a tad off the thud. I've been thinking of trying to figure out why the difference. I thought it might be the latch. But I replaced that and nothing changed. I do know that YEARS ago (I've owned this car for 35 years), I did open the door insides and didn't see anything different - except that the passenger side had a plastic liner and the driver's side did not. I can't imagine the liner is making the difference. But I think that shows that someone had been in there before and maybe they removed something?

    The window frame is a little off. It needs to rotate counter clockwise just a tiny tad.

    But other than that, I don't see anything.

    Does anyone know if there are any things that are special that help ensure that solid thud?

    Jay,

    I wouldn't describe it as a thud...

    Both of my doors 'ring' when I close them.... I'm sure others have the same 'ring', I've heard it in other early 911's...

    Now how to get the same sound (whatever it is) from both doors, the experts will know...

    Cheers and good luck,

    So are you saying THAT door is the off one?! Ha. They both have the ring sound. It is just one sounds more solid than the other. Hmmm.

    I suspect that over nearly 50 years the drivers door has been opened and closed thousands of times more than the passenger’s. One would think that there would be more wear to the hinges and latches as well as simply metal fatigue which could account for the differences.

    I've always thought of it as a ping.

    Yes!!! Love that sound! And as mentioned, my passenger door’s ping is more distinct than the driver’s door.
    Fascinating what makes us Porschephiles smile!

    The ""PING"" harmonic is definitely a sound that is more prevalent on original cars.
    I saw a couple of long hoods last weekend both of which had door off restorations and neither had the piano tuning fork ""PING"".

    One will never be able to get a 911 door closing to sound like a 356. Now that is a sweet sound!
    Sorry, I couldn't help myself.

    If my 356 is anything to go by, that’s more like someone striking a heavy punch bag!
