Our family is growing and we need something a little larger for my wife so we're picking up a lincoln mkx. I was just wondering if all MKX lug nuts are open ended nuts or if the one i'll be purchasing is strange? I was told it was stock and that the center cap protects the wheel studs/lugs from rust but obviously water and salt will get it their causing problems. Anybody have problems with their lug nuts rusting under their center caps? Up here in Canada so salt is abundant!
