The contact owns a 2018 Thor Ace RV. The contact stated that while driving 70 MPH, the vehicle suddenly veered to the right and the driver was no longer able to properly steer the vehicle. A mobile mechanic was called to the location and diagnosed that the front passenger’s side wheel bearing had failed and needed to be replaced. The mechanic stated that the wheel bearing failure was due to insufficient lubrication within the wheel bearing. The front passenger’s side wheel bearing and spindle were replaced, and the vehicle was repaired. The vehicle was later taken to the local mechanic who discovered that the front driver’s side wheel bearing was also failing due to insufficient lubrication. The front driver's side wheel bearing was replaced, and the vehicle was repaired. The manufacturer and local dealer were not yet notified of the failure. The failure mileage was 13,500.
