Doors vibration noises -E39- 1998

[JMVPMD]

Everytime I drive get awful vibration noises coming from both front doors. I sent the car to the dealer but very little have improved and the bill was considerable. I would like to have a look myself. Anybody to instruct me on how to disassemble the front doors of the E 39? thanks. Mike.

first of all, go back to the dealership and complain and get your money back. IF they charged you all the money and did the work that changed nothing, go ahead and complain until you get your money back

Second, i just can't see how the doors would be culpable of this. Think of it like this: i understand if one of the doors would vibrate, but both?!?! i dont think somethign can break or come off from both doors at the same time.

You might need to look at what causes the vibration (such as the operation of your engine, alignment, tires, etc) before taking apart the doors. Are you tires bold? do you have proper alignment? I just really can't see how both of the doors can vibrate unless the doors aren't a problem

That happens to be a common fault with E39's.
It has something to do with the door seals, so say the BMW community.
Personally, I traced mine to the plastic door sills.

Try pressing repeatedly on the door sills and see if they make a squeaking or creaking noise.
If they do, or sound like what you have been hearing (sounds like old ship creaking when the sails are turned hard!) do this:

Carefully pry up the chrome/rubber door sills. (Don't break any clips)
You pry one end and slide (backwards, I think...)
Then holding the whole door sill in your hand, you're able to analyse it better.
Separate the chrome and the rubber pieces.
Apply grease in between the clips and joints, and anywhere that rubs.
Apply grease as well around the holes on the car where the door sills clip onto.
Re install the door sills. It should at least be quieter now.

What happened in mine was when the car moves esp at slow speeds,
the doors (and rubber weather seals) flex and move, and rubs, or press against the door sills. When I was researching, everybody said it was the rubber seals...I didn't think rubber seals would make creaking noises!
But fixing the door sills eliminated my problems permanently...until about maybe 2 years later, when I started to hear a little of it. Probably time to re-grease then.

Note: This solved the problem in my car, and I believe it is the solution to most of the squeaking doors in the E39. However, this is just my opinion. It might or might not help solve yours, but there's no harm in trying it out.
