Just noticed this annoying squeak start up on my truck it only has 3000 miles on it and the rear window squeaks at every bump in the road it's really started to get annoying has anyone else had this problem and if so what did you do to get rid of it lubrication, shimming, anything. The dealer said it was dirty so I cleaned it and it's back after a 100 miles. Any thoughts or suggestions.

 

I had the same problem with my rear sliding window. I sprayed the seals with silicone spray and hasn't squeaked since. Did that over two years ago.

Same problem here. I noticed the sliding section was not very tight in the tracks and was vibrating, causing a squeak. I never open mine so I folded up a piece of paper and pushed it down into the track on the inside to force the window tight against the seal on the outside so it doesn't vibrate. If I used it at all I would take it to the dealer for a new back window assembly.
