Just pull on the back of the caps and kind of wiggle them and they will pop off, the center ones are the hardest to get off, the cover kind of wraps around the back edges but it will come off if you pull hard enough.
The only tools you will need is a torx bit and wratchet...I cant remember what size the bolt is.
those are torx bolts, you just need the correct size "torx" bit to fit.
I took mine off for a day but didn't care for the look on mine for some reason. I got some of those license plate caps from Wal Mart and put them over the screws, I got them in chrome but I didn't like how they looked, It might not look too bad on a dark color if you got the black ones
So i got up this morning and figured i would try and get atleast the crossbars and covers off the roof rack because i only have one torx bit. Well, it just so happens that ONE bit i had was the one i needed, so here are some before and after pics...
The only thing i didnt do was put some sealant on the screws, what kind did you guys use??
Ok, so i can use any sealant, im thinking about painting the bolts a brownish color so that they blend in a little better, they stick out since they are black, will this mess up the threads on the bolts??
