I have a 2000 windstar with 95K miles that had the cradle rust and break at the brackets where the passenger control arm connects. Same general area as your break.
Ford is giving me no help. In my case this break sent the front wheels pointing in different directions. I just thank go this happened in a parking spot and not at highway speeds. Ford has to do something about this before someone is killed.
How did you support the engine and tranmission when you did the replacement? |
