window rattle

[3bears]

so drivers side...if cold or wet my drivers window rattles going down...warm and dry...nope
assume its grease related...haven't torn into it yet...if in the tracks etc...whats best way to clean it and best grease for real cold...like minus 40

IMO, It is unlikely that the big gear or motor drive/gear is causing the glass to shudder as it travels through the tracks. Maybe the tracks have decomposed due to the extreme heat/cold cycles that the 4Runner (and you ) endure up there? Just a suggestion...I could be wrong!
