Default How dangerous is driving a car with a loose bearing?

My echo's back passenger side tire started making a thump thump thump sound as I drove, and has now start screeching a bit when I slow down and turn the wheel. Someone looke dta it and said somehting about the bearing, I was wondering how dangerous it would be to drive it like this until I cna get it fixed, I need to get ont he highway today and no one can fix it soon beign labor day weekend. I'm not a car girl, so of course I worry my tire is going to fall off, I'm wondering whats the most damage it can do.















How could the wheel seize up? I'm confused.















oh my. thank you.

Wheel might seize up. Very dangerous and illegal. Your insurance will be invalid also.































Wheel bearings allow the wheel to run freely. If they are breaking up then it will be metal scraping against metal which will stop the wheel rotating. You will lose control of your car.

it's very unlikely that a wheel will fall off. The noise you hear is metal rubbing on metal which generates heat. Worst case is that it will begin to throw sparks and which could set the car on fire.

The guys are right, the bearing no long have any lubrication and it is making noise. As for your last question, there is no grease inside moving little ball bearing and the little bearing with weight and heat together it will just melt into each other and lock up. The front wheel would either seized up or fall off the vehicle.

right rear, rear wheel? very rare that the bearing go bad.































only way to find out whats wrong is to take a look. maybe during labor day, drop by to some friends house and have a bbq and get the guys to fix your car.































have them jack your car up, remove the tire.















get a hammer and bang on the drum till it comes loose.















remove the drum and you will find your the reason for the problem.















maybe the rear brake component are worn and falling apart.















maybe the wheel bearing, turn the wheel stud and see if it's smooth or making noise.

You're betting your life on a bad part. The wheel is bolted to the spindle which is held by the bearing. When the bearing self destructs, it will let the wheel try to go its own way from the car. That means, the bearing is actually what holds the wheel on the car. If you've ever seen cars that look like they collapsed onto a wheel, that's what happened and why it happened.































Those bearings are pricey- about $200 and you'll pay about $100 to have it replaced. If you were about to be killed unless you gave up $300 why wouldn't you pay?

It is very dangerous and being a Toyota makes it even more dangerous.
