Is it dangerous to drive with a bad wheel bearing?
A wheel bearing goes through several stages as it fails. First, you may hear a clicking while making turns. After that you may hear and feel a pulsing in the car, or a clicking while driving at low speeds. At this point, you MUST replace the bearing. It is extremely dangerous and you are putting your life at risk.A wheel bearing failure at high speed is one of the most fatal ways for a car to fail, so do not drive at high speeds until you can get the bearing repaired. On most cars, it will require a press or other specialty tools, so I would suggest taking your vehicle to a shop so that it is installed correctly. If you are familiar with the construction, function, and assembly of the bearing and axle it can be done at home.
