My 99' 996 Cab top has a minor rattle that seems to be becasue the top has not closed as tightly as it could be. The rattle sound only happens when going over rough pavement. Is there a simple way to tighten up the cab top so that it seats a little tighter when it is closed. This is not a huge issue but a little annoying to me. Thanks for any help ...

I had the same problem. One of the guys, I think Scouser suggested changing the pins that are attached to the top. They fit into the windshield frame. A new updated part that will work on a 99. Not sure of the part #'s. It was a brilliant idea as it has solved all of my rattles. Get a tube of BMW gummi pfedge and wipe it around the seals. Your car will be silent.

Yes, you need to replace the two forked latch seats in the front window frame. The top will latch into these and the old ones start to rattle. This is a 5 minute operation to replace.

You need to order 3 parts:

1 x 996.561.605.02 Right prong seat

1 x 996.561.606.02 Left pront seat

1 x 999.917.557.00 Krytox lubricant

The lubricant should be applied to the rubber seals "extremely" lightly.

There are TSBs for noises in the cab top. See Loren's TSB pages above.

Any more help needed just hollar.

I did the TSB upgrade and used a little Krytox and still had a sqeaky noise between the top and the front of the car that it seals against when clsoed. I tried more Krytox and more is definitely not better. It squeaked loudly at every turn / bump. Very annoying to say the least.

I wiped all the lube off and it's a little better but it's got to get better than this.

Does anyone have suggestions before I go see a dealer?

Thanks

I think that I got this one figured out.

In one of the earlier notes ... it was stated to use the Krytox "extremely" lightly.

This is critical. Use it very lightly and the noises go away completely.
