Are there any videos on removing roof rack from 2004 sienna? Main question is how to remove the end caps without breaking them, and how to “fill” the resulting holes waterproof.
I have to ask - why? I’d remove the crossbars, leave the side rails alone.
You’ll probably not get the caps off without some damage. As far as the holes, a good outdoor silicon sealant will work. Just clean the area well and rough up the area with fine sandpaper. A friend that used to buy old police cruisers swears by it. Leave a good sized cap over the hole to let the sealer bite as much surface around the hole as possible
