Front Suspension problems of the 2001 Ford E-450

We believe this motor home was sold to us with dealership knowing of axle problem, causing RV unable to have wheel alignment corrected. Front rear axle has slipped causing driving hazard. May have caused further damage to vehicle making it unsafe to operate. Rv had numerous smaller problems with this last one being the worst. This has caused us lots of loss of time to travel and enjoy the RV. Was advised not to take any long trips because of problem. Was on a vacation when problem with shower pan occured and shade broke and drawers broke. At same time refrigerator leaked water onto wood floor, which needs to be replaced. In addition, this has created an impairment of market value because of defects in this vehicle.
