If you have a bad wheel bearing, you should stay off the roads until you can get to a mechanic. If your wheel bearing has been damaged, then it could cause you to lose a wheel or lose control of your steering.
You should probably get the car towed to the mechanic instead of attempting to fix it yourself. The cost to get it towed may or may not be included in the warranty, depending on specific terms. You should also call before to let your mechanic know that you’ll be bringing the car in for what you suspect is a bad wheel bearing.
