Default wind noise

So how many of you Bonnie owners have replaced the door weather stripping on your older cars?

I hate wind noise, especially at higher speeds. I know some noise is going to happen from the road and wind, but my car is excessive. There is also a drip at the door L/* top when it rains. I can push my finger thru the seal and get wet, so I know it is the seals.

I am wanting to replace all 4 door seals and door jam seals.
Anyone know of a good place to get the seals?

The window felts seem good. I won't know for sure until I replace the door and jam seals though. This is my April project so I would like to order parts soon(by month'* end) to get things ready for a rubbery weekend!

No need to replace the seals completely. Seal shrinkage is common in the 92-99 model and will eventually lead to interior leaks.

Simply remove the existing seals and clean the edges real well. Then, get a piece of scrap stripping/seal from the wrecker. Dry fit your existing seal once everything is cleaned up. Tuck it real well in the corners. Leave the gap at the bottom of the jamb. Using the scrap piece you got from the wrecker, but a piece to fill the gap. Then, glue everything with 3M weatherstripping adhesive. Problem solved, and cost you no more than $20.

I've done this to three of our four Bonnevilles.

Moved to 92-99.

Hmmm, not sure I understand?

The seals I have look good, no tears or gaps and are soft, however they don't provide a good seal. Maybe they are too flat(compressed)?

Wouldn't a new seal be thicker/puffier?

Over the years the seal has retracted.
I didn't realize this, but one day I was poking around my passenger side seal and noticed it was completely off at the fender side! I peeled the whole thing off, started at the top and re-worked the seal in place, using a bit of black silicone of the stubborn spots. I then filled the gap left at the bottom with a little piece from a yard, and the car was much quieter.

I got so excited, I did the other three doors, and it worked out great.

Good luck!

Adam

They shrink and pull away at the corners adjacent to the B-pillar. Pull them out, get them warm and flexible inside (oven on warm works great), then work them back in starting at the top, tight in the corners, and leave the gap at the bottom.

Do it now. As they get worse, they'll start dumping rain in your car.

Well, I did this today and it was a 100% quieter!
I left the gaps open on the bottom like on Will'* car.
Thanks again!

Awesome photos I just noticed some leaks in mine and am going to check this out ASAP. My trunk is a different story though, that thing gets puddles in it so bad that my spare tire is now useless from rust.

Tonesta have you checked your rear wheelwells to see if they are rusted through, allowing rain water to leak into your trunk? I had that happen in my lesabre and my Bonneville.
