Im running a 04 QC 4x2, and sometimes my windows when i roll them down it seems like a spacer has already feel loose and the windows rattles a little bit. Very very little bit. There's a sound sometimes too that sounds... i guess kinda rocky and knocking. Its not very loud and not everytime. Just curoius if this has happened to anyone else, or if it was because of a few accidents ive been in.

 

Mine are completely normal sounding. Perhaps they just didn't adjust them properly when they were re-installed after the accident.
