It's been a little while since I've posted guys, but my truck has been making me scratch my head. It's an '06 quad/short with almost 40K on it. The problem is with the power-sliding rear glass. recently, it has started creaking upon hitting bumps and going over the burm on my driveway (as the truck flexes it seems). But it's only when the truck flexes. I actually can't tell if it's the sliding glass or the stationery pieces of glass on either side making the noise. Any of you guys have to deal with this before? Is there a fix or am I just gonna have to deal with it?

 

Same thing just started to happen with my '06 this past winter. It seems to no be as bad with the weather a bit warmer. Haven't had the time to check it out yet, but I just assumed it's just another creak...

 

It is the bump stops that the glass is resting against when closed. Also the felt weatherstripping as well gets dirty and stiff when cold. For the bump stops use a little WD to keep the stops slick and take alittle air preasure to it to blow out dirt and such. Mines a power slider so I'm able to relieve how tight it gets with the switch. Too is is most common on all rear sliding window exspecailly in colder climents.

 

Mine did the same thing, Believe it or not one of my cloth headrests was in backwards and was pressed hard up against the back window causing a sqeak when I was driving. I flipped it around and no more sqeaking.

 

Mine did exactly the same thing, i.e. made the noise when the truck body flexed. Dealer replaced the whole window under warranty.
