I have been in and out of the dealer several times trying to fix my windows rattling/squeaking problems

Yet, the front two windows' rattling/squeaking keep on coming back..and the sound is like rubber squeaking on the window whenever I go over bumps or uneven terrain

I am thinking to apply some Lithium grease (where they are usually used for auto door hinges) on the upper rim of the window such that some of the grease will rest on the rubber seal inside...

Yet, I am not sure if there is any problem with applying Li grease there..
any advice?

This topic has been covered many times, use the search engine.

You don't say what year your car is, but see the attached link: http://infinitihelp.com/Ownership/Bu.../ITB03-071.htm

First see if you have the felt strip or not. Then use the silicone (not lithium, yuk) spray from 3M as directed.

Thanks for the comment =)

I have indeed searched.. and the TSB has been applied by my dealer
(with the felt pad + the shortening of the bolts at the bottom of the window assy)

FYI: my car is 2004 sedan

Yet, the rattling just keeps on coming back..

and my biggest concern to this possible fix is that whether Lithium grease is safe for the rubber seal + is the Lithium grease good for window tint? cause I plan to apply some Lithium grease (and spread evenly) onto the top rim of the window and just close it and re-do this a few times to have the Lithium grease "lubricates" the rubber seal at the top part of the door assy

FYI: the dealer said they have applied the silicone based grease.. yet, the rattle just seems to come back after like 2 weeks, which makes me think that it is the grease that has been worned out too quickly

As of now, I believe I will ditch the idea of Lithium grease, but stick with silicone grease for awhile and keep reapplying =)

My 2004 sedan came with the felt strips. I replaced them myself using the TSB, then applied the silicone according to the TSB. It worked, but every month or so I do have to reapply the silicone, but it does work.

I havent searched on this paticular rattle so flame away... I have 05 and there seems to be an unstoppable rattle coming from the passenger tweeter. Any one find away to deal with it? The dealer has been very helpful and has ordered a new assy to replace the one in my door now.

Both the dealer and I have added felt and rubber dampeners to prevent this. If the passenger places their finger on the tweeter grill the rattle stops but nothing else had worked.

I guess just like what have been said, the felt pad is working the way it should be: to reduce the rattling..yet, I guess the seal is still rubbing against the window, which causes the squealing

Thus, I believe I would try to reapply silicone grease every now and then according to the TSB

However, does anyone know if we have to take anything apart to re-apply the grease? coz the TSB isn't very clear on this

I have used the 3M Silicone they call for in this TSB on other applications, and it seems to work pretty good, doesn't have the odor of the cheaper silicone lube I've had before. The method the TSB shows, with a cloth is probably your best bet.

Btw, do you guys know where can I get the 3M silicone lubricant (spray type)?

I used to borrow my neighbour's...but they just said they lost it ...lol

I tried Home Depot, but they don't seem to have it

I got mine at NAPA, don't know if you have them in your area.

we do ! I will try that after work tmr =)

Got one more thing to look forward to lol..

BTW, I just checked my car, that weather seal comes out and goes back in very easily.

Get Dow 111 silicone lube. It works.

i have had my car since oct 1st and ive been having these rattles here and there. i did get the seat replaced around window trim but rattles still seem to be there when going over bumps or if car is sea-sawed on an angle grRRr

I will try to do that tonite =)
yet, which part of the weather seal you have taken off easily?

cause I am wondering if I need to take off anything to reapply
the silicone lube

EDIT: correct me if I am wrong, according to the TSB, we only need to remove the door glass run (weatherstrip) when installing the felt tape?

I brought my G35x to the dealer 4-5 times for rattling. They said they fixed them but low and behold they would come back. Just like my squeaky brakes, I have learned to deal with it.
