Well people will tell you different things but to free it up I suggest wd40 its temporary and does a decent job breaky crud up and lubricating with ruining anything (did antenna on my wifes van yesterday). So tilt it up put a tube on spray backwards where the sunroof goes and on the tracks where it sits, let it sit a few min then try it. Then repeat until you get the desired result, being of course an open sunroof. Good Luck.
Well after the WD40 and freeing it up use any good white litium grease. I use the wal mart brand, it works well for me. Problem is the grease doesn't free anything up. Thats why I said WD40 first. :thumbsup:
