i tried to get mine covered under warranty but it is not because it is a 'wear and tear item' like previously stated. I believe it is covered under the maintenance warranty, but not the extended warranty. It costed me about $600 to replace. I wouldn't wait until it tears and lets out all the grease. Could lead to more damage and therefore cost you more.

If it does tear, you will notice alot of grease on the rim and wheel well. I believe you can also hear a clunking noise when you turn the steering wheel.
