My car has a faulty wheel bearing,in the past i have tried to determine which one it is but with no success.
Does anyone know of a tester i can fit to the wheels to find out which one is vibrating.I have already tried the method of jacking the car then wobbling the wheels to inspect for movement but this hasnt worked

The wheels in question are rear wheels with no steering/trackrod/ball joints there is no heat build up and the bearings are factory sealed parrellel type that cannot be opened without destroying them

There are electronic ears that you can attach to the area where you think the noise is coming from. Then you can drive while listening for the noise. They are expensive. An alternative is to buy a mechanics stethoscope, extend the hose with similar diameter long rubber hose, tape the metal rod to the area near the wheel bearing, then listen as you drive. Switch to the other side and drive again.

There isn't a tester specifically for this. If there is no heat buildup after say an hour of driving I would probably look further maybe brakes or suspension. Usually I do a wobble test first, if that fails a heat check, if still no I usually pull out the bearing and look for heat marks, pits grooves but I know you don't have this option. The only other thing I can think of in your case is to pull off one of the bearings and give it a spin with your fingers holding the inner race and feel how smoothly it spins. Hope this helps!!

If there is no looseness, it could be a seal has given way and the bearing is dry. Pull the wheels and look for evidence of grease on the inside of the hub.

You can get a heat sensor that tells the temperature of things you aim it at. This would tell you which one is heating up. If it is bad, it has to heat up quite a bit more than the others, so this tester will do the trick. You can get one from sumittracing.com, or jegs.com as they sell these to test for many different things such as you are talking about.
Glad I could help. Good Luck!!!

I'm assuming there is noise comming from the bearing. The easiest way to determine what side it is comming from is to drive down the road and swerve back and forth to shift the weight of the car. The car should get quieter and noisyer as it rolls back and forth. whichever side is noisyest (the opposite of when the noise goes away) is your problem bearing.

What makes you think it's a bearing? After a long drive a wheel with a bad bearing should be noticeably hotter. If you test it this way then drive somwhere where you won't be using the brakes.

How do you know its a bearing? If it does not wiggle its something else. Could be a tire out of balance or something more critical such as a tie rod end, ball joint or a host of other critical suspension parts. See a mechanic.

You have to take the hub and the bearing out to tell witch one in bad To tell a bad one they turn blue the little rollers have pit marks in them you all so have to check the race that is what the bearing rids on it should be smooth.

you can find a wheel bearing tester next to the brake light tensioners at the part stores

aren't the wheel bearings usually on the front of the car - just replace them both before it causes you a steering problem
