I've had 4 crown vics and 1 Lincoln Town Car and had to change out the rear axle shaft bearings/seal 3 out 5 vehicles and twice on the Lincoln Town Car. I had to change the entire axle shaft 2 out of 5 vehicles because I drove on a bad bearing for too long and it made a deep groove in the axle shaft
