I have, and I know many other owners have too.... removed the lower plastic rock gaurd for that very reason...
for some reason that lower, bends very easily on its rivets/bolts...... and doesn't seem to cure very straight....
I know some of the owners have actually sanded and razor bladed off enough material to get it to work....
so you have 2 choices here.... assuming, your tire isn't a different size that before....
