45,000 KM 2007 XT (about 30,000 miles). 3 years old. Always in a tropical hot environment that has killed many wheel bearings on my previous cars.

I have a dull whine in the back at 80km/50 mph or more... it doesn't change pitch with acceleration. I think it's a wheel bearing (I can't decide which side) but it might be a diff issue. Is there any way to tell?

hello!

Hi there,

Sounds to me like a wheel bearing,mine did the same,usually jack up the car and check for any play by holding the wheel and wobbling from side to side,though there was no play in mine i noticed the noise got louder on right hand bends as the weight of the car shifted,pointing me to the left hand bearing.Very unusual for a diff bearing to go,they are pretty much bullet proof!

Check for play in the wheel and also check to see if the sound changes when you shift weight side to side on turns etc. If so its probably the wheel bearings

Good ideas - the only problem now is finding a corner I can safely go around at 80kmh (in Singapore!).... :)

If there's play in any of your wheels, you're on the verge of catastrophic failure.

Here's a good way to check:

With all four corners off the ground, spin the suspect wheel while placing your other hand on the coil spring. Any roughness in the bearing will be transmitted and felt through the coil spring.

I eventually replaced the bearings (inner / outer and seals). It made a huge difference in the sound.
