They are super easy to change, you just take a small screw driver and push the center of each plastic rivit in around the outside of the arch and then just pop it off (has 4 clips behind it that just pull off). Stick the new one on and put 7 new plastic rivets in - they work just like rivets, you just need a special plastic rivet gun to put them in which is $30 bucks at Napa or online. If your paying someone to do it - it probably took me 15 minutes a wheel to do the arches - they are quick and easy - 1 - 1.5 hours max for labor if the wheels are already off.
