First time minivan owner. 2021 Sienna with 20,000 miles. I noticed our sliding doors make some slight thumbing sounds this weekend, and after closer inspection I'm 90% sure it was just some caked dust on the sliding door tracks.

Any recommendations for lubrication type and where to use. There appear to be 3 different tracks, one above door opening, one below, and one to left of C pillar. The track that has visible lube is the one above the door, which seems odd.

dry lube, like graphite, I believe is whats supposed to be in there. anything that is "wet" will collect dust and dirt and gum up.
