I was going to make a thread about this the other day. Mine has been doing it only on the drivers door. Couldnt figure out why it was doing it since I clean the truck like every week. It gets really annoying and hurts the ears when you try to roll the window up or down. I will have to try this when I get a chance. Probably this weekend.

 

Well, on the way home today I listened to the squeak and it sounds A LOT like it is coming from the upper track area, so not so sure the pulley lube will quiet mine down. Probably will try anyway (nothing much to lose). I had tint film added to my front windows when it was almost new. Wondering now if that might be the root of my problem. Any ideas on this and how to lube this issue?

 

I thought all this time that my squealing was coming from the glass rubbing on the rubber...it WAS NOT! Even after I took the door panel off...operated the window...I still said to myself, "this has got to be the glass rubbing". I run my finger along the rubber/felt areas, nothing felt abnormal...no dirt, dust, or anything. So I operated the window and put my ear down at the bottom of the door...seemed to be more pronounced down there...so I lubed the pulley, it stopped...voila, couldn't hardly believe it myself. Remember, I had all my upper track area and window seals changed at the dealer...still did it.

I suspect the sound is resonating up through the glass.. If your window/s is/are squealing like mine did...almost makes you cringe...embrasses you to operate them when people are nearby...I would bet, almost guarantee, it's the pulley/cable/track assembly...even though it don't sound like it.

If you're getting a 'chirp' when you hit bumps and such...just q-tip some lube into the side seal tracks on the door...the felt will wear off in little spots near the bottom of the window and cause a 'chirp' when hitting bumps/humps/etc.

A small warning: Do not get lube/grease/etc on the white cable covers the crisscross inside the door. If you have ever noticed, you may see a little streak on the center of your window...these cable covers rest against the glass when the window is down...grease/lube would create a real pita every time you put the window down.

It's a trick to the get to the pulleys...they're 'in there'...use a lube, in my case Corrosion-X, with a tube that you can get in there and aim with one hand while you squirt with the other hand.

 

All four of my windows squealed on my 07 Lariat. Brought it in to the dealership And they changed out all four of my regulators and now I'm squeal free. What a difference. My drivers door rattled over certain bumps and got that fixed too. I'm now happy to drive my truck again.

 

I'm bringing this one back from the dead.

I took off my rear door panels today to assess the situation. The squeal was becoming unbearable, not to mention highly embarrassing. Once I got the panels off, I quickly realized that the upper pulleys on both doors were definitely the culprit. With the window in the full up position I was able to get a good amount of PB Blaster White Lithium on the pulleys. I also lubed the vertical tracks for good measure. Within a few full up/down cycles the squeal has gone away.

I was running short on time (due to rain) and did not get to the fronts. I will try to lube those on the next dry day.

 

Just a little update. I realized why removal of the front door panels was giving me fits...the speakers have to come out/off first!

I now understand what I was doing wrong. I just thought I'd share this with the rest of ya. Enjoy!

 

So I found out something today that I'd thought I'd share with the rest of you. If you think that your window squeal might be coming from the upper pulleys...well you DO NOT have to take the door off to get the pulleys lubed up.

If you roll the windows all the way down, you can then pull back the window scrapers enough to see both pulleys from the window crack. With the small hose on the white lithium you can almost get right down ontop of the pulleys. It's nearly impossible to do this and not get lube on the windows...but it's MUCH easier and quicker than pulling the door panels and messing with the door liners.

I just thought that I'd share this with you fellas. It's nice to have quiet windows now. It's actually kinda funny that I now have to turn my head to see if the windows are going up and down, whereas previously I could just hear them. I guess that's not a bad trade off right?
