rattling/squyeaky windows

[markus]

i have been noticing ever since i bought the car if i have my drivers side window down about half way my window will make an awuful rattling noise. some of the other windows will actually squeal when going down. what can i do to fix this? i was thinking about spraying some silicone into the window tracks but does anyone else have another idea?

you need to replace the window sliders inside the door and re-lube the tracks. leave the tracks you see alone. The sliders range from 80 cents to a couple bucks each mattering where you get them. There are 2 for each door.

My driver's window made an awful noise before i replaced those. They were a snap (literally). It took more time to get the door panel off. You'll need a screwdriver, phillips for the 2 screws that hold things onto the door panel, and flat helps to pry the sliders free from the window regulator.

Wow, an inexpesnive part! Thanks for the suggestion/link, I will pick a couple of these up as well. I think regular use really keeps things smooth and quiet, the front windows and doors are more silent than the rears for me.
