why has my right rear wheel bearing started to go bad with less than 70,000 miles on the car? is it under warranty?

I got the car at Lithia I have had 2 different techs inspect and I gave the wheel an up and down shake and there was play. it is rear drum with abs. If the part was a couple of dollars I would do it myself. I know how this happens and if the people who are transporting cars for you are not Ford but independent you can charge them. I also have the kick panel driver side out side under door splitting at the seem. The rubber strip that lines the drivers door is ripped and coming apart. The warranty package that came with the car has so many different things it cov ers and different time frames that I can't figure it out I would appreciate it if you could tell me if this stuff is covered under warranty It was making noise and the noise went away

How do you know it's the wheel bearing? Does it make a noise or does the car shake?

It should be under warranty if it has 70,000.

Check your warranty. Ask the dealership where you made your purchase. Are you absolutely sure it's a bad wheel bearing??
