I have a 2008 SR5 with 85K miles and I roll the tailgate window down all the time.
It is starting to develop a squeak when rolling down and I'm trying to find instructions to clean & lube the tracks, and any other mechanisms in there to keep it running smoothly. Searched several areas in the forum and came up empty handed.
Has anyone done this maintenance, or can point me toward a write-up I may have missed?
