I just dealt with my end caps about an hour ago. They are held on by 3 bolts and all 3 were torx bolts on mine. :fs1: The nut is a 10mm. It is a PIA to get up in there, especially if the rubber dirt shield is still intact. On the P side, the vacuum canister can be in the way. If you have the time and tools, here's what I would do. Detach the dirt shield from the bumper. Detach the bumper brackets from the frame (3 bolts/side). Don't forget to support the bumper during removal. Now you can inspect and correct any abnormalities regarding the bumper, brackets, and end caps without having to deal with tight, blind spaces. :thumbsup:
