we have a severe wobble/shutter in our new f150 ecoboost - had it in shop in Brandon, Fl they replaced drive shaft and carrier bearing - Feduke Ford in Vestal,NY replaced transfer case, shimmed pinot angle 2 times after field engineer Joe Tomaso came to dealership - Joe Tomaso's answer was " this is as good as it gets" - I find it hard to believe that ford can continue to sell this vehicle when they are aware that it is defective - we use our truck to pull our camper, boat or a small trailer - under load it feels like the truck is going to shake apart - also it is very noticeable when truck is empty - start feeling wobble at around 4 to 6 mph - we were told that we pay to much attention to the truck when truck starts moving that we should just ignore it - nobody seems to no if this is a safety issue? Does anyone no when truck will eventually have major problems? We are very happy with truck and only want the wobble fixed - very unhappy with our salesman Chris Goffa, Vestal, NY and Warren Weeks, service mgr, Vestal, NY they have never made any follow up calls to us.
