The consumer took the vehicle to be inspected. This is when the mechanic noticed that the front wheel bearings on the left and right side needed to be replaced. There was three inches of looseness up and down, left and right on both wheel because of bearing failure. The vehicle was taken to the dealer and they agreed that the bearing were worn. The vehicle had exceeded the 36000 mile warranty by about 200 miles, therefore the consumer had to pay for the repairs. The consumer was also informed that there were no grease fittings which is why the bearings had to be replaced. Manifold/gasket leaked due to poor design.
