I managed to get my tub realigned & the diff re-centred by the dealership under warranty.
All I had to do was bend my axles in my original diff, argue with the dealership wether they were or not, finally get the diff replaced, poorly; take it back because the new diff was making a screeching noise during hard cornering, pick it up after they couldn't fix it, get onto Ford direct & kick up a stink, take my car back to the dealership. More head scratching, in & out a few times, noticed paint was worn though where the wheel was rubbing on the tub at some stage while trying to figure out what was going on at home for them, get that resprayed & tub aligned, still making noise, take it back again & again, finally get one of my axles shortened by 35 thou... 3 months later & in total 7 trips to the dealership & probably 50 odd phone calls- now it looks sweet. Just like it should've always been.
Got them to take off the mud flaps & respray rear of the tub too.
Totally worth all the hassles & head aches. Love ford, always a pleasure.
